NEW YORK (Reuters Life!) - Eating chocolate could bring down cholesterol levels -- but only in small amounts and only in some people, according to an analysis of eight studies.

Dr. Rutai Hui of the Chinese Academy of Medical Sciences and Peking Union Medical College in Beijing and colleagues found chocolate only helped people who already had risk factors for heart disease and only when consumed in modest amounts.

Eating moderate amounts of cocoa could be "a worthwhile dietary approach" for preventing high cholesterol in certain groups of people, the researchers concluded in a report in the American Journal of Clinical Nutrition (here).

The analysis came after several studies suggested that chocolate may be good for your health.

One study released in March showed that among 19,300 people, those who ate the most chocolate had lower blood pressure and were less likely to suffer a stroke or heart attack over the next 10 years.

But, like the new analysis, that research came with caveats; the difference in chocolate consumption between the top and bottom chocolate-consuming groups was around 6 grams, or about one-seventh of a Hershey's milk chocolate bar.

Hui and his colleagues searched the medical literature to find studies that looked at how cocoa affected blood fats, or lipids, and found eight trials including 215 people.

When all studies were analyzed together, the researchers found eating cocoa cut levels of LDL, or "bad" cholesterol, by about 6 mg/dL and reduced total cholesterol by the same amount.

But cocoa had no effect on cholesterol in the three highest-quality studies.   Continued...
