More exercise, less high blood pressure

People who continue to exercise throughout their lifetimes are far less likely to develop high blood pressure and the more they exercise, the less likely they are to develop high blood pressure (Journal of Hypertension, June 2008). In various studies, up to 91 percent of the North American population suffers from high blood pressure which puts them at markedly increased risk for strokes, heart attacks, kidney damage and arteriosclerosis. Virtually all scientists agree that this frightening incidence of high blood pressure is caused by lifestyle, and the major lifestyle factors are lack of exercise, obesity, and eating too many calories, refined carbohydrates and saturated fats.For some people, but not all, increased intake of salt also contributes...

Measure Abdominal Fat, Not Just Weight

Researchers at the University of Michigan report that not all people who are fat are at high risk for heart attacks (Archives of Internal Medicine, August, 2008). They showed that 51 percent of overweight adults (36 million Americans) have normal blood pressure, cholesterol and blood sugar, while 25 percent of normal- weight Americans (16 million) have high levels of at least two of these tests. The media picked up this study with headlines such as "Better to Be Fat and Fit Than Skinny and Unfit" (New York Times, August 19, 2008).However, the entire study is flawed. The authors measured overweight, not abdominal obesity. If you just compare weight to height to define obesity, more than 50 percent of professional football players would be obese,...

Saturated fat risks cancelled by exercise

The Masai of Kenya and Tanzania eat the same type of high animal-fat diet as North Americans, but they have a very low incidence of heart attacks. In spite of the large amount of saturated fats in their diets, they have lower body weights, waist measurements, blood pressures and cholesterol levels (British Journal of Sports Medicine, July 2008). This is explained by the fact that the average Masai burns 4,000 kilocalories a day, which is roughly equal to walking 12 miles every day (this number includes the amount you burn for normal daily activities such as breathing and sleeping).Saturated fat is the dominant fat in meat, chicken and whole milk dairy products. It raises cholesterol only when a person takes in more calories than he burns. A...
