There were no real surprises for me in the article entitled “Television Viewing and Risk of Type 2 Diabetes, Cardiovascular Disease, and All-Cause Mortality” by Anders Grøntved and Frank B. Hu that appeared in the Journal of the American Medical Association (JAMA 2011;305(23):2448-2455). As stated in the abstract: “Prolonged television (TV) viewing is the most prevalent and pervasive sedentary behavior in industrialized countries and has been associated with morbidity and mortality. However, a systematic and quantitative assessment of published studies is not available.”
The authors performed an analysis of eight previously published studies to determine the association between TV viewing and risk of type 2 diabetes, fatal or nonfatal cardiovascular disease, and all-cause mortality.
The risk of all-cause mortality appeared to increase with TV viewing duration of greater than Read more »

People with metabolic syndrome are twice as likely to develop heart disease, and five times as likely to develop diabetes, as those who don’t have metabolic syndrome. But many people are not yet familiar with this relatively new term. Do you know what metabolic syndrome is?
OECD Country Populations with a BMI > 30 (1996-2003)
Metabolic syndrome is the combination of several medical problems associated with morbid obesity. In addition to obesity, these conditions include: Read more »

There are few medical conditions that people fear more than a stroke. We know that blood pressure control and lowering cholesterol levels reduces stroke risk. Now, thanks to a huge analysis from Italy published in the Journal of the American College of Cardiology, we know that higher dietary consumption of potassium is associated with lower rates of stroke and could also reduce the risk of coronary heart disease and total cardiovascular disease, too. What is even more remarkable is that the results apply to all parts of society and not just to specific “at-risk” subgroups.
Most doctors aren’t even aware of how important it is to eat potassium-rich foods. And what are these foods that have potassium? Surprise: It’s fruits and vegetables like bananas, tomatoes, oranges, apricots, most legumes, spinach, winter squash, avocado, kiwi, and cantaloupe. Actually, almost all fruits and veggies have moderate to high potassium content.
The researchers looked a number of well-done studies that included 247, 510 participants over age 30 and found that those patients with the higher potassium intake reduced their stroke risk by 21 percent. The Italian doctors say the protective effect of potassium against stroke is in part due to its blood pressure lowering effects and also due to other properties of the potassium mineral, such as the inhibition of free radical formation.
I’ve written before about the DASH diet, which also found that reduction of sodium and addition of fruits and vegetables to the diet is an effective way to control blood pressure. The DASH diet is high in potassium.
Think about it: Did you have five servings of fruits and vegetables today? Numerous studies have shown their life-prolonging benefits. This new study just adds to what we already know. I challenge all readers to keep a diet count and make sure you are eating five fruit and vegetable servings a day — every day — to help reduce your risk of stroke, cancer, and heart attack.

Add coronary stent thrombosis to the list of cardiac events influenced by circadian rhythms, with more events occurring during the early morning hours and in a summertime window of late July and early August.
Coronary stent thrombosis joins several other adverse cardiac events that also follow a circadian pattern, such as stroke, unstable angina pectoris, acute myocardial infarction and sudden cardiac death, according to researcher published in JACC: Cardiovascular Interventions.
Most studies that addressed circadian variations in cardiovascular disease were done before the advent of stents, so, researcher from Mayo Clinic-Rochester conducted a retrospective analysis of medical records and the clinic’s registry, finding 124 patients who presented with coronary stent thrombosis between February 1995 and August 2009.
Researchers determined the time of day, day of week, and season of year that the stent thrombosis occurred and recorded when potential triggers were present. In addition, the team categorized each stent thrombosis based on the number of days since the initial stenting procedure: early=0 to 30, late=31 to 360 days, very late=more than 360 days.
The association between the onset of stent thrombosis was lowest at 8 p.m. and highest at 7 a.m. (P=0.006). However, when the team divided the analysis into early, late, and very late stent thrombosis, only the association between early stent thrombosis and time of day remained significant (P=0.030, P=0.537, P=0.096, respectively). Day of week wasn’t associated, but stent thrombosis rates peaked between the end of July and the beginning of August (P=0.036). Read more »

Enriched chicken feed may have resulted in eggs having less cholesterol and more Vitamin D than previously measured, reports the U.S. Department of Agriculture (USDA).
A large egg today has about 185 milligrams of cholesterol, down 14 percent from 215 milligrams in 2002, according to new research from the USDA’s Agricultural Research Service, reports USA Today. Also, an egg today has 41 international units (IUs) of Vitamin D, up 64 percent from 25 IUs measured in 2002. (That’s still only about 7 percent of the 600 IUs recommended per day.)
The agency regularly does nutrient checks on popular foods, this time analyzing eggs taken from store shelves in 12 locations around the country. The American Egg Board said in a press release that hen feed is made up mostly of corn, soybean meal, vitamins and minerals. Nutrition researchers at Iowa State University are also looking into reasons why cholesterol in eggs is decreasing.
The government’s “Dietary Guidelines for Americans” recommend that most people eat less than 300 milligrams of total dietary cholesterol a day, and people at a high risk of cardiovascular disease should eat less than 200 milligrams a day. The average American man consumes about 337 milligrams of cholesterol a day and the average woman consumes 217 milligrams, reports the Los Angeles Times.
One egg a day fits within the average, healthy American’s diet, reports WebMD, citing research funded by the Centers for Disease Control and Prevention and by the American Egg Board — owners of the slogan “the incredible, edible egg.”
