Teenagers who smoke and are around second-hand smoke are putting themselves at more risk for of metabolic syndrome, a condition marked by obesity, high blood pressure, unhealthy cholesterol levels and pre-diabetes according to a study printed in the medical journal "Circulation" Monday.

"This is the first study to link this syndrome, which most people associate with obesity, to secondhand smoke," Dr. Michael Weitzman of the University of Rochester in New York, who led the study told Reuters

Drinking a small amount of alcohol with an evening meal may increase the risk of low blood sugar the following day in patients with type 1 diabetes, the results of a study published in Diabetes Care suggest.

"There is no evidence to suggest that individuals with type 1 diabetes adopt a different approach to their use of alcohol than the rest of the population," Dr. Tristan Richardson and colleagues from Royal Bournemouth Hospital, UK, write

A study done by Tufts University in Boston reveals eating dark chocolate lowers high blood pressure and stabilizes insulin levels as well as improve blood vessel function in patients.

Dr. Jeffrey B. Blumber says, "The findings do not suggest that people with high blood pressure should eat lots of dark chocolate in lieu of other important blood pressure-reduction methods, such as medication and exercise. Rather, we are identifying specific flavonoids that can have a benefit on blood pressure and insulin sensitivity

Researchers report that dark chocolate may help lower blood pressure.

The study shows compounds found in chocolate, called flavonoids, can help blood vessels work more smoothly, with the possibility of reducing heart disease

An experimental treatment shows positive results for helping patients suffering from diabetes regain their ability to make insulin.

Such help would lessen the need for shots to regulate normal blood sugar levels
