(You Can’t Gain 5 lbs of Fat by eating 2 lbs of Chocolate or 2 lbs of Sugar!)

In a recent article in the May 14, 2012, issue of Newsweek on the subject of the Anti-Obesity Campaigns, the author indicated that the CDC, the NIH, and the Institute of Medicine got it all wrong. The article said that not all calories are equal, fats (beef) are not a problem, sugars and starches are the only culprit, and exercise doesn’t help at all.

You think you know, but maybe you don’t. Did you know that some of us have higher or lower blood pressure in one arm than in the other? Why is this important? Well, a report in the British Medical Journal in March 2012 says it is.

Studies have shown that a difference of 15 points (15mm Hg) between your right and left arm is associated with a higher incidence of peripheral vascular disease, cardiovascular disease, and all-cause mortality. There may even be a significantly increased risk when the difference is 10 points (10mm Hg) between your arms.

How frequent is this? In one study, 24% of patients had a difference of 10 points and almost 10% had a difference of 15 points or more (mm Hg). So, make sure your health care provider takes your BP in both arms. This is particularly important to any of us who are under treatment for hypertension (high blood pressure).  We have to be certain that our response to medication is being monitored in the same arm each time.

It’s vitamins…some might be killing us.

So now you might get the idea that taking some vitamin supplements may be doing you no good at all or even doing you some harm. If that’s what you think, there’s a lot of evidence to suggest you’re right. Let’s review what the Medical Letter said in the December 2011 issue about some pretty popular supplements in regard to benefits and risks.

Vitamin E in food can be somewhat different than vitamin E in most supplements. For example, the vitamin E in food is gamma tocopherol. The vitamin E in supplements is mostly alpha tocopherol which can actually block the antioxidant activity of gamma tocopherol (in food). It can also interfere with vitamin K metabolism and your blood clotting mechanism.

But…what is DNA and what does it mean? Well, the actual chemical name is deoxyribonucleic acid, but we don’t have to remember that. For better or worse your DNA is the stuff that makes you what you are. It’s inside the nucleus of every cell in your body except the red blood cells {they don’t have a nucleus}. Within our DNA lie our chromosomes that contain all of our genes (our entire genetic code)…the molecular code that is unique to each individual. It’s the code that determines the color of your eyes, your hair, and your propensity to have heart disease or stroke or any one of a number of different kinds of cancer.  Your DNA is not only who you are but also who you could become.
