The Benefits of Exercise Go Beyond Prevention….

July 23, 2009

We all know the benefits of exercise.  It has been shown to afford a better lifestyle due to prevention of chronic diseases associated with sedentary behavior. 

What we dont know is how following a rigorous physical activity and being FIT can have an impact on a patients recovery from certain illnesses that unfortunately can happen due to the NON modifiable risk factors like family history and age!

A study from the Mayo Clinic published in BMJ this month shows us that indeed the benefits of exercise can go beyond Prevention:

______________________________________________________________________________

Background: The importance of physical activity as a modifiable risk factor for stroke in particular and cardiovascular disease in general is well documented. The effect of exercise on stroke severity and stroke outcomes is less clear. This study aimed to assess that effect.

Methods: Data collected for patients enrolled in the Ischemic Stroke Genetics Study were reviewed for prestroke self-reported levels of activity and 4 measures of stroke outcome assessed at enrollment and approximately 3 months after enrollment. Logistic regression was used to assess the association between physical activity and stroke outcomes, unadjusted and adjusted for patient characteristics.

Results: A total of 673 patients were enrolled; 50.5% reported aerobic physical activity less than once a week, 28.5% reported aerobic physical activity 1 to 3 times weekly, and 21% reported aerobic physical activity 4 times a week or more. Patients with moderate and high levels of physical activity were more likely to have higher Barthel Index (BI) scores at enrollment. A similar association was detected for the Oxford Handicap Scale (OHS). After 3 months of follow-up, moderate activity was still associated with a high BI score. No significant association was detected for activity and the OHS or Glasgow Outcome Scale at follow-up after adjustment for patient characteristics.

Conclusions: Higher levels of self-reported prestroke physical activity may be associated with functional advantages after stroke. Our findings should be seen as exploratory, requiring confirmation, ideally in a longitudinal study of exercise in an older population.

______________________________________________________________________________

Theoritically, the study results are obvious in that according to the author….”A brain that generally has good blood and oxygen flow from aerobic exercise will be in a better position to compensate for neurological deficits caused by a stroke.”

The results also say it all: that Exercise indded can be beneficial in all phases of the disease from prevention to recovery.  

 Among patients who reported less exercise in the year before their stroke those individuals were significantly more likely to have one or more bad outcomes while those who were into moderate to high levels of activity, the odds of a better outcome were higher. 

Likewise, in terms of recovery and functional capacity post stroke after three months , individuals who had both moderate and high exercise levels were associated with significantly better functional outcomes.  Great News specially to our diabetic patients who love to exercise! 

There you go… the many wonders of exercise !!!

You Get Everything GOOD with EXERCISE!  


The 20-40 RULE in Fitness and Disease

July 13, 2009

My 20-40 rule:

A low fitness level in your teens translate to a high level of risk for developing diabetes by age 40! 

That’s the message I got from this study published in Diabetes Care called the CARDIA Fitness Study.

_____________________________________________________________________________________________

Objective: Test the association of fitness changes over 7- and 20-years on the development of diabetes in middle-age.

Research Design and Methods: Fitness was determined based on the duration of a maximal graded exercise treadmill test (Balke protocol) at up to three examinations over 20-years from 3989 black and white men and women from the Coronary Artery Risk Development in Young Adults study. Relative fitness change (%) was calculated as the difference between baseline and follow-up treadmill duration/baseline treadmill duration. Diabetes was identified as fasting glucose ≥126 mg/dL, post-load glucose ≥200 mg/dL, or use of diabetes medications.

Results:

  • Diabetes developed at a rate of 4 per 1000 person-years in women (n=149) and men (n=122) and lower baseline fitness was associated with a higher incidence of diabetes in all race-sex groups (hazard ratios from 1.8 to 2.3).
  •  On average, fitness declined 7.6% in women and 9.2% in men over 7 years.
  • The likelihood of developing diabetes increased per standard deviation decrease (19%) from the 7-year population mean change (−8.3%) was in women (hazard ratio [HR]=1.22, 95% CI: 1.09, 1.39) and men (HR=1.45, 95% CI: 1.20, 1.75) following adjustment for age, race, smoking, family history of diabetes, baseline fitness, body mass index (BMI), and fasting glucose.
  • Participants who developed diabetes over 20 years experienced significantly larger declines in relative fitness over 20 years vs those who did not..

Conclusions: Low fitness is significantly associated with diabetes incidence and explained in large part by the relationship between fitness and BMI.

___________________________________________________________________________________________

This study shows that inidviduals risk to develop lifestyle related diseases especially diabetes are at increasing overtime depending on the level of fitness:

  • Women were at 22% increased risk of developing diabetes
  • men were at a 45% increased risk…

 for every standard deviation decrease from the mean fitness change.  This relationship continued to exists even after adjusting for age, smoking, family history of diabetes, and baseline fasting glucose.  In fact the researchers noted that the baseline BMI was a better predictor for developing diabetes than the baseline fasting glucose as well as baseline fitness.

What Do These Data MEAN?

  • If two individuals have similar fitness level; the bigger person with a higher BMI is more likely to develop diabetes than the smaller frame guy overtime in the next 10-20 years.
  •  The possible mechanism by which fitness decreases risk for diabetes is most likely related to the regulation of body mass.  A lower BMI means better insulin sensitivity and less production of toxic substances by increased adiposity that can lead to further cardiovascular complications associated with obesity and diabetes. 

The authors conlcuded:

That regular physical activity to “improve and maintain cardiorespiratory fitness is an important component of a healthy lifestyle.” 

 AMEN!


Walk and Jog or The WOG… A Perfect Exercise!!!

July 7, 2009

Since the time Ive lost weight, Ive been apporached several times by my friends how I did it.  Ive posted in thia website my diet regimen…now I am posting my exercise routine.  To lose weight…the right food and the right discipline are both essential.  To maintain your weight, then the right kind of exercise that you feel good and you can do for years should be the best way to increase your metabolic rate!

Can we call it the WOG?  Short for Walk and Jog!!!

Ive been a brisk walker for sometime.  I find it a good exercise that’s not too tiring nor too destructive for my joints.  But overtime, after several articles touting the benefits of short bouts of exercise in between breaks that I thought of trying to alternate my walking exercise with jogging.

The intensity of exercise is more…the surge of adrenaline is more and boy…you feel better and better everytime you do the routine.  Lots and lots of sweat too!  Besides, you allow you body to rest in between the jogging by brisk walking.

Jogging being a high-intensity exercise kicks your metabolism up and by doing so,  your metabolic rate stays up longer (five times longer after a vigorous workout than after an easy one).   By doing the same routine, one therefore tends to add up the number of calories burned because the jogging can easily add up another 200 calories compared to walking alone.

Here’s what I do:

Before I walk, warming up by stretching the muscles is very important.  Then I start my brisk walking slowly increasing the pace  until I start jogging. 

 I then do the alternate walk and jog routine every 3 minutes until 40 to 40 minutes!!!!  

Initially it may seem “laborious” compared to walking alone but soon…you will be running a marathon as the running becomes easier.  But at this time, I have no plans to pursue a running career!  I just want to burn more calories and make myself healthier and hopefully avoid myself getting the risk of developing diabetes!

To stay Fit and Slim…Discipline is the KEY!

You are What You Eat and Do the WOG!


Sleep Well To Prevent High Blood Pressure!!!

July 4, 2009

A simple measure to reduce BP is to have a good night’s sleep!!!

Here’s a new study that shows us one tip to have a better controlled blood pressure  published in Archives of Internal Medicine:

________________________________________________________________________________

BACKGROUND: Epidemiological studies have reported an association between self-reported short sleep duration and high blood pressure (BP). Our objective was to examine both cross-sectional and longitudinal associations between objectively measured sleep and BP.

METHODS: This study is ancillary to the Coronary Artery Risk Development in Young Adults (CARDIA) cohort study. Blood pressure was measured in 2000 and 2001 and in 2005 and 2006. Sleep was measured twice using wrist actigraphy for 3 consecutive days between 2003 and 2005. Sleep duration and sleep maintenance (a component of sleep quality) were calculated. Analyses included 578 African Americans and whites aged 33 to 45 years at baseline. Outcome measures were systolic BP (SBP) and diastolic BP (DBP) levels, 5-year change in BP, and incident hypertension.

RESULTS: After we excluded the patients who were taking antihypertensive medications and adjusted for age, race, and sex,

  • shorter sleep duration and lower sleep maintenance predicted significantly higher SBP and DBP levels cross-sectionally as well as more adverse changes in SBP and DBP levels over 5 years (all P < .05).
  • Short sleep duration also predicted significantly increased odds of incident hypertension (odds ratio, 1.37; 95% confidence interval, 1.05-1.78).
  •  Adjustment for 16 additional covariates, including snoring and daytime sleepiness, slightly attenuated the associations between sleep and BP.

 CONCLUSION: Reduced sleep duration and consolidation predicted higher BP levels and adverse changes in BP, suggesting the need for studies to investigate whether interventions to optimize sleep may reduce BP.
______________________________________________________________________________

There you go guys… nake sure you sleep better..and rest well. 

Dont let worries or pressure bother you too much. 

Associate the bed with a good night’s sleep…  not only will you feel refreshed the next day BUT healthier too!

For a Healthier Heart… Sleep Well!!!


What’s Really the IDEAL Weight To Live Longer?

July 2, 2009

My brother in law’s blog article had this title: A Little Extra Weight can Make you Live Longer! 

That obviously caught my attention.  So searching the source of the article was actually published in the  OBESITY journal  June 2009.  Below is the abstract:

_____________________________________________________________________________________________

Although a clear risk of mortality is associated with obesity, the risk of mortality associated with overweight is equivocal. The objective of this study is to estimate the relationship between BMI and all-cause mortality in a nationally representative sample of Canadian adults.

A sample of 11,326 respondents aged 25 in the 1994/1995 National Population Health Survey (Canada) was studied using Cox proportional hazards models.

  • A significant increased risk of mortality over the 12 years of follow-up was observed for underweight (BMI <18.5; relative risk (RR) = 1.73, P < 0.001) and obesity class II+ (BMI >35; RR = 1.36, P <0.05).
  • Overweight (BMI 25 to <30) was associated with a significantly decreased risk of death (RR = 0.83, P < 0.05).
  • The RR was close to one for obesity class I (BMI 30–35; RR = 0.95, P >0.05).

Our results are similar to those from other recent studies, confirming that underweight and obesity class II+ are clear risk factors for mortality, and showing that when compared to the acceptable BMI category, overweight appears to be protective against mortality. Obesity class I was not associated with an increased risk of mortality.

____________________________________________________________________________________________

But a Word of Caution …..

As clearly stated by Mark Kaplan, DrPH, the coauthor: “Our study only looked at mortality, not at quality of life, and there are many negative health consequences associated with obesity, including high blood pressure, high cholesterol, and diabetes.”

What made the study interesting were the following outcomes:

  • Overweight individuals were 17 percent less likely to die than normal weight inidividuals. 
  • Not surprising are the outcomes for the underweight people as they were noted to be 70 percent more likely than people of normal weight to die. 
  • The same outcome was noted with the extremely obese people who were 36 percent more likely to die.

The problem of the study is it only looked at mortality data and nothing else. One may have lived longer but the quality of life due to disabling complications arising from chronic conditions associated with obesity is poor. 

And this has always been our battle cry for a healthy lifestyle and achieve a healthy normal weight:

  •  To reduce the risk for chronic diseases that can cause disability and that
  •  Excess weight can shorten your lifespan…

The bottom line is: 

  • A Little overweight is better than having excess weight BUT
  •  

  • Normal weight should continue to be The Goal … and always
  •  

  • AIM to Achieve a healthy lifestyle to live longer because:

 Quality is More Important Than Quantity!


How To Exercise To Reduce Heart Disease…

June 30, 2009

We heard the news of Michael Jackson’s death.  It is known that Heart disease continues to be a leading killer worldwide.  Blame it to lifestyle and the world’s reliance to fast food and technology.  In parallel to the rise of heart disease is the rising prevalence of Diabetes and Obesity which I believe will no longer spare anyone because of the environment we are in and the kind of acitvities and lifestyle the next generation is in and will have!

It is therefore imperative that we deal with this rising prevalence of heart disease upfront and not relying heavily on medications to get us through!  Simple steps can be done but steps that need diligence, perseverance and discipline!  It is therefore best to start these steps NOW than later!

I myself am doing these steps NOW and not later when I will get the disease of Diabetes due to age and strong family history. 

The recent guideline of the American Heart Association is timing to the events around the world. 

There’s no better time than now to emphasize lifestyle change and exercise but now!  So what do we recommend?

_____________________________________________________________________________

To improve cardiovascular risk, it is recommended that patients with T2DM accumulate a minimum of 150 minutes per week of at least moderate-intensity and/or 90 minutes per week of at least vigorous-intensity cardiorespiratory exercise.

In addition, resistance training should be encouraged. These guidelines can be achieved with varying contributions of moderate- to vigorous-intensity cardiorespiratory exercise.

Patients should train on at least 3 nonconsecutive days each week to maximize benefits. Individual sessions should last for no less than 10 minutes.

 Sedentary behaviors should be minimized. Exercise training should be implemented long-term.

______________________________________________________________________________

Additional recommendations highlighted in the guidelines include:

  • Resistance training should use all muscle groups and progress to  2–4 sets of 8–10 repetitions at a weight that cannot be lifted >8–10 times, with 1–2 minute rest periods between sets.
  • The duration of each individual session can vary, although the aim should be a minimum of 10 minutes per session, at least 3 sessions per day.
  • Patients who elect to walk should perform the task at a brisk pace to be effective.
  • Go guys… jump on to the bandwagon.  Just look around you.  Lance Gokongwei has joined the fitness world!  So can we!

    It’s in the decision When to start that somehow manages to make us Weak and defenseless. Be determined and do it now. 

    Be Fit…Be Slim…

    Be Smart and Be Healthy!


    The Balance of Work and Rest

    June 29, 2009

    This month has been extra busy for me.  Usual excuse for having neglected this website for almost a month!!!! 

     After attending the Annual Endocrine Society Convention in Washington DC…  before I overcame my jet lag, I had a scheduled lecture on Diabetes Management in Tagaytay attended by around 250 doctors nationwide.  Then another scheduled lecture within that week in Manila attended by another 250 doctors from Asian Countries in Dusit Hotel.  Immediately after my lecture , I had a scheduled meeting  with the Board of the American Association of Clinical Endocrinologists Philippine Chapter for our joint international meeting in Mactan Shangrila with AACE US in August.  

    Then…. I have to go back to Cebu by that day because it was going to be Fathers Day the nxt day and I promised myself to spend that day with my wife and kids!  And boy did we have FUN!  

    Without asking permission from my kids ( which am sure they wont say YES)  the next day I have to fly back again to Manila to attend another meeting then flew back to Cebu the next day to give another lecture Tuesday night in Marriot Hotel. 

    And in between those scehdules were scheduled meetings with the Pharma Industries Product Managers and National Sales Managers.  WHEW!!!!

    Finally the weekend came!  Rewarding myself with a weekend in Shangrila Mactan with my Saturday off and spending that day for leisure was worth the break I needed.  Spending time with my kids and pampering myself with a massage were rejuventaing enough for another week of work!

    I guess in life… to enjoy one’s work, one has to balance it with fun and rest!  If one has time to spend work with and for others…so much more of a reason that one should and MUST  FIND time for yourself and your family!  I guess it’s an OBLIGATION rather than a LUXURY!

    For me…money should NOT be the sole purpose of living but we USE money to provide a better life for you and your loved ones!  Therefore to achieve that purpose is to prioritize yourself above money and to make sure one has the Best of HEALTH to be able to achieve what you want to pursue in life.  Never should WEALTH take over HEALTH!

    The balancing act in life  maybe difficult but if practiced in ones life… this can lead to a more productive , Healthy and FUN environment for yourself and your loved ones. 

    And if possible…balance your work with rest and fun everyday and every moment you can! 

    Enjoy Your Day Folks… and Glad that AM BACK!


    How To Lower Cholesterol Levels Naturally

    June 3, 2009

    Here’s one interesting article from the Harvard Health Publications HealthBeat on ways we can do to lower cholesterol naturally without meds:

    _____________________________________________________________________________________________

    15 tips for lowering your cholesterol naturally

    Many factors contribute to the development of heart disease or stroke. Genes and gender play a role, but for most of us, what we eat is an important factor as well. The good news is that a few small changes to your diet can help lower your cholesterol, which in turn will lower your risk for heart disease and stroke. Here are 15 heart-healthy eating tips to help you in the fight against high cholesterol.

    1. Eat meat sparingly. Relegate meat to a minor part of your diet instead of making it the centerpiece of most meals. Trim off fat and skin from meats and poultry. Avoid fatty cuts of beef, pork, and lamb; instead choose lean meats, or substitute fish or skinless white-meat poultry. When dining out, choose a smaller portion of meat, or meatless pasta or fish dishes.

    2. Opt for low-fat dairy products. Avoid dairy foods that contain whole milk or cream; instead, use low-fat or nonfat versions.

    3. Watch the snacks. Choose low-fat snacks (homemade popcorn, carrots, dried fruits, or fresh fruits) instead of high-fat ones (potato chips and candy bars). Avoid store-bought bakery products unless they are explicitly low in saturated fats and free of trans fats.

    4. Cut down on saturated fat in cooking. Use liquid cooking oils rather than butter or margarine. Use nonstick pans. Instead of frying your food, bake, broil, roast, steam, or stew. Discard drippings, and baste with wine or broth.

    5. Avoid palm and coconut oils. Most vegetable oils are unsaturated, but these two contain mostly saturated fat. Choose canola, sunflower, safflower, corn, soybean, olive, and peanut oils.

    6. Reduce dietary cholesterol. Strive to eat less than 200 mg of dietary cholesterol a day. Limit eggs to no more than four egg yolks per week; two egg whites can replace a whole egg in most recipes. Limit lean meat, fish, and poultry to no more than 6 ounces per day (a 3-ounce portion is about the size of a deck of playing cards). Stay away from cholesterol-rich organ meats, such as liver, brains, and kidneys.

    7.  Increase complex carbohydrates and fiber. Emphasize foods with complex carbohydrates—such as fruits and vegetables, whole-grain products, and legumes (dried beans and peas)—that are low in calories and high in fiber. Eat more water-soluble fiber, such as that found in oat bran and fruits. This type of fiber can significantly lower your blood cholesterol level when eaten in conjunction with a low-fat diet.

    8. Eat fruits and vegetables. To protect your heart, eat plenty of fruits and vegetables.

    9. Go for nuts. Nuts are associated with a lower risk of heart disease. They’re a healthful and filling source of protein, but go easy on them; they have lots of calories, so too much could cause weight gain.

    10. Add fish to your diet. Countries with high fish consumption have a lower risk of death from all causes as well as from cardiovascular disease. Like nuts, oily fish contain the essential fatty acids known as omega-3s and omega-6s. Since our bodies can’t make these, we have to eat foods that contain them to gain their benefits, which include improved cholesterol levels.

    11. Reduce salt intake. High blood pressure is a major risk factor for cardiovascular disease. Diets high in salt increase risk of hypertension.

    12. Avoid trans fats. According to the Institute of Medicine’s Food and Nutrition Board, there are no redeeming qualities to trans fats, and no safe levels. They raise LDL cholesterol and lower HDL cholesterol. The National Cholesterol Education Program urges people to eat as little as possible. Avoid or eat only very small quantities of foods that list hydrogenated oil or partially hydrogenated oil among their first ingredients. These products contain a lot of trans fat.

    13. Drink alcohol only in moderation. Regular, moderate drinking can reduce the risk of cardiovascular disease, but heavy drinking negates the benefits. Moreover, the advantages aren’t strong enough to recommend alcohol for anyone who doesn’t already drink. For those who do, the Dietary Guidelines for Americans recommend no more than one drink a day for women, and one or two drinks a day for men.

    14. Read labels carefully. Avoid prepared foods that list any of the following among the first few ingredients: meat fat, coconut or palm oil, cream, butter, egg or yolk solids, whole milk solids, lard, cocoa butter, chocolate or imitation chocolate, or hydrogenated or partially hydrogenated fat or oil. Watch out for fast foods and other unlabeled products; when you don’t know what you’re getting, eat sparingly.

    15. Change strategies. If three months of healthy eating doesn’t bring your total and LDL cholesterol levels into the desired range, consult your physician and a dietitian. If the numbers still don’t budge after six months, it may be time to consider medication.

    ___________________________________________________________________________________________

    Simple measures we can at home to avoid getting th compications associated with a high cholestrol level in the blood.  High cholesterol levels have been shown to increase ones risk to suffer from stroke and heart attack. 

    The good news is , we now have ways to control and lower the cholestrol levels by taking care of what we eat and through medications.

    Be Health Smart and Check the Labels!


    Intelligence Equates Fitness!

    May 29, 2009

    I found this very interesting article and I find it rather amusing… linking inteligence to physical fitness.   This is the first time I have read such a study published in the journal Intelligence and I want to share the information to all….

    _________________________________________________________________

    We suggest that an over-arching ‘fitness factor’ (an index of general genetic quality that predicts survival and reproductive success) partially explains the observed associations between health outcomes and intelligence. As a proof of concept, we tested this idea in a sample of 3654 US Vietnam veterans aged 31–49 who completed five cognitive tests (from which we extracted a g factor), a detailed medical examination, and self-reports concerning lifestyle health risks (such as smoking and drinking).

    As indices of physical health, we aggregated ‘abnormality counts’ of physician-assessed neurological, morphological, and physiological abnormalities in eight categories: cranial nerves, motor nerves, peripheral sensory nerves, reflexes, head, body, skin condition, and urine tests. Since each abnormality was rare, the abnormality counts showed highly skewed, Poisson-like distributions. The correlation matrix amongst these eight abnormality counts formed only a weak positive manifold and thus yielded only a weak common factor.

    However, Poisson regressions showed that intelligence was a significant positive predictor of six of the eight abnormality counts, even controlling for diverse lifestyle covariates (age, obesity, combat and toxin exposure owing to service in Vietnam, and use of tobacco, alcohol, marijuana, and hard drugs).

    These results give preliminary support for the notion of a superordinate fitness factor above intelligence and physical health, which could be further investigated with direct genetic assessments of mutation load across individuals.

    _________________________________________________________________

    This study showed that being healthy is linked to being more intelligent.  And this relationship is linked to a certain genetic “fitness factor” that regulates both the health fitness  to that of brain intelligence.  

    In other studies, the relationship was believed to be more of a “cause and effect” relationship where by being more intelligent means more likely to live a healthy lifestyle by eating the right kind of food and knowing the benefits of exercise.  Unfortunately, this cause and effect relationship may not be that simple after all because I know of intelligent people who may not be at their best of fitness level.

    On the other hand, the researchers further noted that the lower intelligence predicted health problems more than deviant lifestyle factors like smoking or alcohol intake.

    All these date suggest that there indeed is the existence of a genetic ‘fitness factor’ that influences both health fitness and the way our brains work!

    Look Smart By Being Fit!!!!


    The Alcohol Paradox

    May 16, 2009

     I came across a short review on the paradox of alcohol from the Harvard Newletter which I want to share.  Its concise and full of facts worth reading.

    We may not know it but alcohol can have good benefits too… to Health.

    ___________________________________________________________________________________________

    Drinking increases “good” HDL cholesterol, reduces factors in blood that make it more likely to clot, and may directly affect blood vessels, keeping the linings smooth and pliable and thus less vulnerable to atherosclerosis. European researchers reported interesting findings in 2008 that show a connection between alcohol intake and higher blood levels of omega-3 fats. Indeed, temperate tippling has been associated with everything from greater bone density to less risk for Alzheimer’s disease and vascular dementia, as well as protection against heart disease and stroke.

    Moderation is paramount when it comes to alcohol, because drinking too much is patently ruinous. Triglycerides and blood pressure go up. Binge drinking can lead to stroke. Moderation is flexibly defined, but the American Heart Association guidelines are often cited: for men, one to two drinks a day; for women, just one. A drink is defined as a 12-ounce beer, 4 ounces of wine, or 1.5 ounces of 80-proof liquor.

    Women do need to worry about alcohol increasing breast cancer risk. Alcohol may drive up estrogen levels, and estrogen seems to play an integral part in the development of many breast cancers. However, at moderate amounts (the drink-a-day level), the risk is small. Folic acid may help offset the breast cancer risk posed by alcohol, so women who drink are encouraged to get an extra 400 micrograms per day.

    ___________________________________________________________________________________________

    Just like anything we do and eat:  Do and Eat the amount that is not more than what can harm you! 

    The line between the good and the  bad effects can be so thin that you may not know it…you are already crossing the line!

    So They Say:  DRINK MODERATELY!   Now you know what it means!


    WHY Breastfeed?

    May 8, 2009

    Go to fullsize imagehat breastfeeding is best for babies…now we know its also good for mothers as well.  Good news for those who believe in the benefits of breastfeeding based on a new study publsihed in the recent journal of Obsetrics and Gynecology, May 2009: 

    ___________________________________________________________________________________________

    OBJECTIVE: To examine dose-response relationships between the cumulative number of months women lactated and postmenopausal risk factors for cardiovascular disease.

    METHODS: We examined data from 139,681 postmenopausal women (median age 63 years) who reported at least one live birth on enrolling in the Women’s Health Initiative observational study or controlled trials.

    RESULTS: Dose-response relationships were seen; in fully adjusted models,

    • women who reported a lifetime history of more than 12 months of lactation were less likely to have hypertension , diabetes, hyperlipidemia, or cardiovascular disease than women who never breast-fed, but
    • they were not less likely to be obese.

    In models adjusted for all above variables and BMI, similar relationships were seen. Using multivariate adjusted prevalence ratios from generalized linear models,

    • we estimate that among parous women who did not breast-feed compared with those who breast-fed for more than 12 months, 42.1% versus 38.6% would have hypertension, 5.3% versus 4.3% would have diabetes, 14.8% versus 12.3% would have hyperlipidemia, and 9.9% versus 9.1% would have developed cardiovascular disease when postmenopausal.
    • Over an average of 7.9 years of postmenopausal participation in the Women’s Health Initiative, women with a single live birth who breast-fed for 7-12 months were significantly less likely to develop cardiovascular disease  than women who never breast-fed.

    CONCLUSION: Among postmenopausal women, increased duration of lactation was associated with a lower prevalence of hypertension, diabetes, hyperlipidemia, and cardiovascular disease.

    ___________________________________________________________________________________________

    What this study showed is that women who breastfed for more than one year throughout their lifetime were 10% less likely to have a heart attack or stroke.  But what’s important is that these breastfeeding women were also less likely to develop the dreaded metabolic syndrome: 20% less likely to develop of diabetes, 12% less likely to have hypertension and 19% less leklely to develop high cholesterol. 

    How long should one breastfeed top get the effect?  Well, even women who had breastfed for only one month had lower rates of diabetes, high blood pressure and high cholesterol.

    Why do benefits result with breastfeeding? 

    Well most likely women who breastfeed their babies are more careful with their health in terms of food habits and lifestyle.  Likewise the hormone oxytocin produced during breastfeeding have the capacity to relax the vessels that may play a role in delaying plaque buildup in the vessel walls.

    There you go guys…

    Breastfeeding is Good for Our Health!


    L-Carnitine and Weight Loss…

    April 28, 2009

    Go to fullsize imageIve seen my friends drinking juice with L carnitine thinking that by doing so…they are enjoying the taste plus the calories from the juice while the Carnitine burns the fat that makes them lose weight.  This would be an ideal setting and definitely one that will earn the founder of this promise of weight loss while enjoying the food will win the Novel Prize Winner in Science….

    All in the game of marketing and the problem is…these products are winning high in sales because people are easily fooled by marketing.  Just like our kids are fooled into eating fried chicken because they’re healthy!

    Carnitine is an important nutrient.  It is one that helps the body turn fat into energy.  So marketing the product from this basis : enjoy the taste of juice while burning your fat and lose weight…is one marketing that is really stretching the facts too lame!  Unfortunately people buy the ads as if they are the truth!

    Lastly beware of websites from companies selling the product…claiming facts regarding carnitine and products that they sell… because bias in reporting data is always evident.   Be vigilant when searching for them in the internet.  Always check the source and its realiability of the findings including the institution that claims the facts!!

    The truth of L carnitine is that at present and quote from the University of Maryland website: NO PROOF!

     “Although L-carnitine has been marketed as a weight-loss supplement, there is no scientific evidence to date to show that it improves weight loss. A recent study of moderately overweight women found that L-carnitine did not significantly alter body weight, body fat, or lean body mass. Based on the results of this one small study, claims that L-carnitine helps reduce weight are not supported at this time.”

    Licking Speeds Up Wound Healing….

    April 15, 2009

    Call it reflex but the moment something feels painful or see blood in our fingers or hands, we immediately bring that finger into our mouth to lick it!  We feel better and we think it stops the bleeding.

    Now science tells us indeed we were right all along.  A recent study published online by FASEB showed that licking a wound can indeed speed up wound healing:

    ___________________________________________________________________________________________

    Wounds in the oral cavity heal much faster than skin lesions. Among other factors, saliva is generally assumed to be of relevance to this feature. Rodent saliva contains large amounts of growth factors such as epidermal growth factor (EGF) and nerve growth factor (NGF).

    In humans, however, the identity of the involved compounds has remained elusive, especially since EGF and NGF concentrations are 100,000 times lower than those in rodent saliva.

    Using an in vitro model for wound closure, we examined the properties of human saliva and the fractions that were obtained from saliva by high-performance liquid chromotography (HPLC) separation.

    • We identified histatin 1 (Hst1) and histatin 2 (Hst2) as major wound-closing factors in human saliva.
    • In contrast, the D-enantiomer of Hst2 did not induce wound closure, indicating stereospecific activation. Furthermore, histatins were actively internalized by epithelial cells and specifically used the extracellular signal-regulated kinases 1/2 (ERK1/2) pathway, thereby enhancing epithelial migration.

    This study demonstrates that members of the histatin family, which up to now were implicated in the antifungal weaponry of saliva, exert a novel function that likely is relevant for oral wound healing.

    ___________________________________________________________________________________________

    Now we know why nature tells us to lick our wounds…why dogs and cats do it too!!!!  This study also explains why mouth sores heal easily even if we dont do anything to them.

    Hopefully in the future, this will help scientists develop new and better ways to help heal the wounds especially among those with diabetes or poor circulation that require the most aggressive way of treating the wounds to avoid complications like amputation.

    For now…if you can lick it… go for it!!!!


    Meat Is Not NEAT!

    April 7, 2009

    Go to fullsize imageIt is easier to convince a child to eat meat than to eat veggies.  This scenario is given.  We are exposed to too many ads on meat whether chicken meat or beef meat on TV and newspapers.  It is therefore a challenge to parents to introduce other varieties of food that we deem healthier to the next generation.  It may take us some time to be successful but a little step can indeed go a long way overtime!

    Now comes another study to support the concept that meat is really not neat!  Published in the latest edition of  Archives of Internal Medicine:

    ____________________________________________________________________________________________

    Background  High intakes of red or processed meat may increase the risk of mortality. Our objective was to determine the relations of red, white, and processed meat intakes to risk for total and cause-specific mortality.

    Methods  The study population included the National Institutes of Health–AARP (formerly known as the American Association of Retired Persons) Diet and Health Study cohort of half a million people aged 50 to 71 years at baseline. Main outcome measures included total mortality and deaths due to cancer, cardiovascular disease, injuries and sudden deaths, and all other causes.

    Results  There were 47 976 male deaths and 23 276 female deaths during 10 years of follow-up.

    • Men and women in the highest vs lowest quintile of red (HR, 1.31 [95% CI, 1.27-1.35], and HR, 1.36 [95% CI, 1.30-1.43], respectively) and processed meat (HR, 1.16 [95% CI, 1.12-1.20], and HR, 1.25 [95% CI, 1.20-1.31], respectively) intakes had elevated risks for overall mortality.
    • Regarding cause-specific mortality, men and women had elevated risks for cancer mortality for red (HR, 1.22 [95% CI, 1.16-1.29], and HR, 1.20 [95% CI, 1.12-1.30], respectively) and processed meat (HR, 1.12 [95% CI, 1.06-1.19], and HR, 1.11 [95% CI 1.04-1.19], respectively) intakes.
    • Furthermore, cardiovascular disease risk was elevated for men and women in the highest quintile of red (HR, 1.27 [95% CI, 1.20-1.35], and HR, 1.50 [95% CI, 1.37-1.65], respectively) and processed meat (HR, 1.09 [95% CI, 1.03-1.15], and HR, 1.38 [95% CI, 1.26-1.51], respectively) intakes.
    • When comparing the highest with the lowest quintile of white meat intake, there was an inverse association for total mortality and cancer mortality, as well as all other deaths for both men and women.

    Conclusion  Red and processed meat intakes were associated with modest increases in total mortality, cancer mortality, and cardiovascular disease mortality.

    _________________________________________________________________________________________________________

    This study further confirms the relationship between red meat and cancer, heart and overall risk of death.  Likewise, the study also showed that fish or intake of white meat was associated with a reduction in the risk of death.

    Translating the data to common language…it means…

    Over 10 years, those that eat meat equivalent to a quarter-pound hamburger can increase ones risk to die from cancer by 22 percent and the risk to die from heart disease by 27 percent. 

    Bottom Line is:

    Cut The Red Meat… Enjoy Fish in time for the Lenten Season….


    Take a Nap…Its Good for your Memory!!!

    April 2, 2009

    It is now known that being sleep deprived means…risking yourself to suffer from chronic illnesses including diabetes and heart disease.  Now comes an interesting observation published in Sleep Journal that links sleep to memory….

    __________________________________________________________________________________________

    Study Objectives:

    In this study we examined the benefit of a daytime nap containing only NREM sleep on the performance of three declarative memory tasks: unrelated paired associates, maze learning, and the Rey-Osterrieth complex figure. Additionally, we explored the impact of factors related to task acquisition on sleep-related memory processing. To this end, we examined whether testing of paired associates during training leads to sleep-related enhancement of memory compared to simply learning the word pairs without test. We also examined whether strength of task acquisition modulates sleep-related processing for each of the three tasks.

    Subjects and Procedure:

    Subjects (11 male, 22 female) arrived at 11:30, were trained on each of the declarative memory tasks at 12:15, and at 13:00 either took a nap or remained awake in the sleep lab. After the nap period, all subjects remained in the lab until retest at 16:00.

    Results:

    Compared to subjects who stayed awake during the training retest interval, subjects who took a NREM nap demonstrated enhanced performance for word pairs that were tested during training, but not for untested word pairs. For each of the three declarative memory tasks, we observed a sleep-dependent performance benefit only for subjects that most strongly acquired the tasks during the training session.

    Conclusions:

    NREM sleep obtained during a daytime nap benefits declarative memory performance, with these benefits being intimately tied to how well subjects acquire the tasks and the way in which the information is acquired.

    __________________________________________________________________________________________

    In short…. 

    For a sharper memory… taking a nap can definitely help!

    “Not only do we need to remember to sleep, but most certainly we sleep to remember,” . The main message of the investigator and researcher Dr. William Fishbein, a cognitive neuroscientist at the recent meeting of the Society for Neuroscience.

    So my friends… take a rest in between work…enjoy life… take it easy…

    AND remember to take care of your brain because just like anything else in life…it needs to rest to function better!


    Can I Eat Eggs Everyday? Yes You Can!!!!

    March 28, 2009

    New studies have been made to refute the previous claims that eggs can increase ones cholesterol. 

    A recent article published in the International Journal of Obesity showed that the previous notion of limiting eggs because they can increase cholesterol is no longer an acceptable fear.  In fact eggs can help one lose weight!

    __________________________________________________________________________________________

    Objective:

     To test the hypotheses that an egg breakfast, in contrast to a bagel breakfast matched for energy density and total energy, would enhance weight loss in overweight and obese participants while on a reduced-calorie weight loss diet.

    Design:

    Otherwise healthy overweight or obese participants were assigned to Egg (E), Egg Diet (ED), Bagel (B) or Bagel Diet (BD) groups, based on the prescription of either an egg breakfast containing two eggs (340 kcal) or a breakfast containing bagels matched for energy density and total energy, for at least 5 days per week, respectively. The ED and BD groups were suggested a 1000 kcal energy-deficit low-fat diet, whereas the B and E groups were asked not to change their energy intake.

    Results:

    After 8 weeks, in comparison to the BD group,

    • the ED group showed a 61% greater reduction in BMI,
    • a 65% greater weight loss ,
    • a 34% greater reduction in waist circumference (P<0.06) and
    • a 16% greater reduction in percent body fat (P=not significant).
    • No significant differences between the E and B groups on the aforementioned variables were obtained.
    • Further, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglycerides, did not differ between the groups.

    Conclusions:

      The egg breakfast enhances weight loss, when combined with an energy-deficit diet, but does not induce weight loss in a free-living condition. The inclusion of eggs in a weight management program may offer a nutritious supplement to enhance weight loss.
    __________________________________________________________________________________________
    It is however to be emphasized that in this study, the egg diet was part of a calorie restircted diet suggesting that eating eggs as part of a low calorie diet can help one lose weight.  
    • But the added bonus of the study is the fact that eggs did not have any effect on the blood cholesterol level suggesting that it is really the intake of Saturated fat in the diet found in pastries, cakes and cookies that is harmful to the body!
    • The results of the study  were further confirmed in a similar finding from the University of Surrey research group which showed a similar no effect on cholesterol level with intake of 2 eggs per day for 6 to 8 weeks.
    Hopefully…these two studies can now end the debate as to whether eggs are safe to eat or not.  Enjoy!!!!!

    How Safe Are Artificial Sweeteners….

    March 25, 2009

    One topic that has never died down during these years is the safety of artifical sweteeners.  The problem stems from internet messages and information being propagated by unknown sources regarding the dangers of these products.  As an endocrinologist, I have been recommending these sweeteners to my patients as they actually help stave off the craving for sugar without necessarily increasing the sugar load.

    But how much is enough for these sweeteners?

    Recently the Mayo Clinic organization published views on this controversy and recommendations.

    ___________________________________________________________________________________________

    The Food and Drug Administration (FDA) has approved the following low-calorie sweeteners for use in a variety of foods. The FDA has established an “acceptable daily intake” (ADI) for each sweetener. This is the maximum amount considered safe to eat each day during your lifetime. ADIs are intended to be about 100 times less than the smallest amount that might cause health concerns.

    Artificial sweetener ADI* Estimated ADI equivalent** OK for cooking?
    Aspartame (NutraSweet, Equal) 50 milligrams (mg) per kilogram (kg) 18 to 19 cans of diet cola No
    Saccharin (Sweet’N Low, SugarTwin) 5 mg per kg 9 to 12 packets of sweetener Yes
    Acesulfame K (Sunett, Sweet One) 15 mg per kg 30 to 32 cans of diet lemon-lime soda*** Yes
    Sucralose (Splenda) 5 mg per kg 6 cans of diet cola*** Yes

    *FDA-established acceptable daily intake (ADI) limit per kilogram (2.2 pounds) of body weight.
    **Product-consumption equivalent for a person weighing 150 pounds (68 kilograms).
    ***These products usually contain more than one type of sweetener.

    ___________________________________________________________________________________________

    How about the safety of these products?

    Although this is one product has been bombarded with bad publicity probably because of its popularity being present in almost any low calorie foods to diet sodas… the National Cancer Institute and other major health oragnizations including the American Diabetes Association and the US FDA continue to refute these claims… as so far,  there’s no scientific evidence that any of the artificial sweeteners approved for use in the United States cause cancer and that there are now numerous studies to confirm that artificial sweeteners are safe for the general population.

    I for one contnue to use aspartame or splenda for my coffee eevry morning or in the afternoon. I am a user and a believer in these low calorie sweeteners that as long as used properly and not in excess of what is recommended…then it is safe!

    Enjoy The Sweetness of Health!


    The Nutritional Benefits of Pulses

    March 22, 2009

    Just gave a lecture to a group of food technologist, media personnel and nutritionist on the Nutritional Benefits of Pulses upon the invitation of the United States Department of Agriculture at the USDA Culinary Theater. Fortunately the Philippines now has access to the USDA products of pulses which have been neglected sources of healthy nutrients especially fiber.

    I have been a proponent of healthy foods in my website. I am an advocate of healthy lifestyle for a healthy mind. And I am not hesitant to help promote products that are healthy and nutritious.

    Pulses are actually edible seeds of legumes. Legumes include the peas, chickenpeas, beans and lentils. The good thing about them is that they are rich in fiber and have low glycemic index. As such, they therefore can be great partners to what we know as healthy diet.

    A cup of cooked peas for example can be packed with fiber and yet very low in glycemic index meaning, the capacity to increase the blood sugar upon ingestion is very low. The combination of these properties provide one an ideal food that can be both filling and nutritious. As a result therefore, one gets to enjoy a food that can less likely contribute to weight gain which we know can lead to more serious chronic illnesses like diabetes, high blood pressure and stroke.

    Several studies have now shown that obesity can lead to serious problems, and pulse based diet has been shown to help curb obesity in certain populations. Anything that can help us decrease the prevalence of obesity in this country and the world is really a welcome addition to our need to find more ways to combat this epidemic. Likewise, intake of pulses in certain regions of the world have been shown in epidemiological studies to result in long life span like the Japanese or the Swiss and reduce the risk of colon Cancer due to their pre-biotic properties. However long term studies need to be done to confirm this finding.

    We don’t go to groceries and easily grab peas or beans in the aisle. We still need to be educated more about these foods and the USDA has led the way in this regard and I am pleased to be part of it. I myself am a fan of peas and beans.

    I have started to educate my kids about the nutritious benefits of eating veggies and slowly and slowly, they’re learning to enjoy the greens more each day. So the next time you go grocery shopping… take a second look at Pulses. They are HEALTHY AND NUTRITIOUS!!!


    Can Vitamin C Help Prevent GOUT?

    March 19, 2009

    Go to fullsize imageGood news for patients at risk of developing gout because a very common remedy and very affordable at that has been shown to help prevent gout.

    A new study published in the latest edition of Archives of Internal Medicine showed a relationship linking higher intake of Vitamin C to lower risk of developing gout:

    ___________________________________________________________________________________________

    Background  Several metabolic studies and a recent double-blind, placebo-controlled, randomized trial have shown that higher vitamin C intake significantly reduces serum uric acid levels. Yet the relation with risk of gout is unknown.

    Methods  We prospectively examined, from1986 through 2006, the relation between vitamin C intake and risk of incident gout in 46 994 male participants with no history of gout at baseline. We used a supplementary questionnaire to ascertain the American College of Rheumatology criteria for gout. Vitamin C intake was assessed every 4 years through validated questionnaires.

    Results  During the 20 years of follow-up, we documented 1317 confirmed incident cases of gout. Compared with men with vitamin C intake less than 250 mg/d, the multivariate relative risk (RR) of gout was 0.83  for total vitamin C intake of 500 to 999 mg/d, 0.66  for 1000 to 1499 mg/d, and 0.55 (0.38-0.80) for 1500 mg/d or greater. The multivariate RR per 500-mg increase in total daily vitamin C intake was 0.83 . Compared with men who did not use supplemental vitamin C, the multivariate RR of gout was 0.66  for supplemental vitamin C intake of 1000 to 1499 mg/d and 0.55 (0.36-0.86) for 1500 mg/d or greater.

    Conclusions  Higher vitamin C intake is independently associated with a lower risk of gout. Supplemental vitamin C intake may be beneficial in the prevention of gout.

    ________________________________________________________________________________________________________

     What the study patients took were supplements of 1,500 mg daily.  What is interesting to note is that for every increase in Vitamin C intake of 500 mg per day, the risk of developing gout was decreased by 17%.

    Likewise, those who took the 1500 mg supplemental form of Vitamin C had a 45% lower risk of developing gout than those who took lower doses of Vitamin C.  On the other hand those that took 1000 mg ov Vitamin had a 34% lower risk of developing gout!

    It is known that Vitamin C can decrease the levels of uric acid oin the blood by increasing its excretion in the urine.

    Does this mean,. we now go ahead and grab more Vitamin Cs in the market? I guess we need to wait for more studies to confirm this finding. 

    But to those who continue to believe in Vitamin C and its role in preventing colds, this is one good news!

    For me… getting the Vitmain Cs from fruits would be a better option.  Remember one orange can give you 70 mg of Vitamin C already.  Plus the ther benefits of fruit intake!


    Reduce Your Risk for Diabetes Through Weight Loss: The Impact of Weight Loss Surgery

    March 9, 2009

    Go to fullsize imageWeight gain and Obesity play very important roles in the development of chronic diseases like Diabetes, High blood pressure and complications like Stroke and Heart Attack.  One therefore has to incorporate proper lifestyle and good behavior through daily physical acitvity to help avoid developing these conditions.  However there are certain inidividuas where weight loss through these behvioral methods no longer are enough to provide the weight loss one desires and therefore for ” medical” reasons, one resorts to drastic measures like Bariatric surgery.

    But do they work in decreasing the risk? or do they help patients improve disease outcomes?

    Now comes s study published in the American Journal of Medicine, March 2009  to show that weight loss indeed can work wonders to diabetes and that bariatric surgery can help:

    __________________________________________________________________________________________

    • 621 studies from 1990 to April of 2006 were analyzed:  78.1% of diabetic patients had complete resolution and diabetes was improved or resolved in 86.6% of patients as the result of bariatric surgery.
    •  Gastric banding yielded 56.7% resolution, gastroplasty 79.7%, gastric bypass 80.3% and BPD/DS 95.1%.
    •  After more than 2 year post-operative, the corresponding resolutions were 58.3%, 77.5%, 70.9%, and 95.9%.
    • The Percent excess weight loss was 46.2%, 55.5%, 59.7% and 63.6%, for the type of surgery performed suggesting that BPD yielded the best result.

    Concluding that:

    • 82% of patients had resolution of the clinical and laboratory manifestations of diabetes in the first 2 years after surgery, and
    • 62% remained free of diabetes more than 2 years after surgery (80% and 75% for the total group).

    __________________________________________________________________________________________

    The study for me tells us one thing: that weight loss indeed can work wonders.  However lets not all resort to surgery to achieve improvement in our risk for diseases as surgery also entails risks! 

    While proper diet and physical activity are completely free and easy to do…all they need are the Two D’s to succeed: DETERMINATION and DISCIPLINE!
