A survey of 146 high school students ranging in age from 13 to 15 found that nearly three out of four of those girls said they are trying to lose weight and just one in four boys said they are also dieting. Researchers add that most of the girls who said they were trying to shed some pounds, didn't need to lose weight. Also, about 44% of the dieting students said they often skip meals to control their weight. The study in The Journal of the American Dietetic Association says these findings are important for parents, teachers and health professionals to understand that teenagers need help in dealing with weight issues in a healthy way.
Researchers looked at nearly 30,000 people in 52 countries and found that 90% of heart attacks can be attributed to nine risk factors. First, smoking takes a lot of blame, and so does an abnormal ratio of the so-called good and bad cholesterol particles in the blood. Those two factors trigger two-thirds of the global risk for heart attack. Also according to the study, other risk factors include high blood pressure, diabetes, abdominal obesity, stress, lack of fruits and vegetables in the diet and lack of daily exercise.
Finally, how much alcohol you drink also plays a role, but that's not necessarily on the bad side. Researchers found people who drink alcohol in moderation have a lower risk than those who don't drink at all.
Late news from Athens, Greece, not about the Olympics, but about your health and chocolate. Most people know by now that dark chocolate is good for you because it is rich in antioxidants. Researchers at Athens Medical School have been diving into dark chocolate to find out why. They say dark chocolate appears to temporarily make blood vessels more flexible, something that could help prevent hardening of the arteries. But before you fill your pantry with dark chocolate, researchers warn that if you eat too much of it, the weight gain from chocolate could cancel out the benefits.
