The findings come ___36___ a study of nearly 1,000 US people that looked at diet, calorie intake and body mass index (BMI) - a measure of obesity.___37___ is found that those who ate chocolate a few times a week were, on ___38___, slimmer than those ___39___ ate it occasionally. Even though chocolate is loaded with calories, it contains ingredients（材料）that may favour weight loss ___40___ than fat synthesis, scientists believe.___41___ boosting calorie intake, regular chocolate consumption was related to lower BMI in the study, ___42___ is published in Archives of Internal Medicine. The link remained even when other factors, like how ___43___ exercise individuals did, were taken into ___44___.And it appears it is how often you eat chocolate that is important, rather than how much of it you eat. The ___45___ found no link with quantity consumed.
___46___ to the researchers, there is only one chance in a hundred that their findings could be explained by chance alone. Lead author Dr Beatrice Golomb, from the University of California at San Diego, said: "Our findings appear to add to a body of information suggesting that the composition of calories, not just the number of them, matters for determining their ultimate impact on weight."This is not the first time scientists ___47___ that chocolate may be healthy for us. Other studies have claimed chocolate may be good for the heart. Consumption of certain types of chocolate has been linked to some favourable changes in blood pressure, insulin（胰岛素）sensitivity and cholesterol（胆固醇）level. And chocolate, ___48___ dark chocolate, does contain antioxidants（抗氧化剂）which can help to mop up harmful free radicals - unstable chemicals that can damage our cells.
Dr Golomb and her team believe that antioxidant compounds, called catechins（儿茶素）, can improve lean muscle mass and reduce weight  ___49___ studies in rodents would suggest this might be so. Mice ___50___ for 15 days with epicatechin (present in dark chocolate) had improved exercise performance and observable changes to their muscle composition.They say clinical trials are now needed in humans to see ___51___ this is the case.
But before you reach ___52___ a chocolate bar, there are still lots of unanswered questions. And in the absence of conclusive evidence, experts advise caution.While there's no harm in allowing yourself a treat like ___53___ now and again, eating too much might be harmful because it often ___54___ a lot of sugar and fat too.And if you are looking to change your diet, you are ___55___ to benefit most from eating more fresh fruits and vegetables.

British researchers are looking for volunteers willing to eat a piece of chocolate daily for a year in the name of science. The trial(实验) will explore whether flavonoids (类黄酮) found in chocolate and other foods can reduce the risk of heart disease.

“We are looking at a high risk group first,” said Aedin Cassidy, a biochemist who will lead the study.

Previous studies have suggested dark chocolate is rich in the beneficial flavonoids linked with heart health, but experts note the high sugar and fat content of most commercially available chocolate might cancel out some of the advantages. Other research has also shown dark chocolate appears to lower blood pressure, improve the function of blood vessels (血管)and reduce the risk of heart attack.

This has encouraged companies to market specific products containing dark chocolate. Mars Inc has introduced Cocoa Via, a line of dark and premium chocolates that plays up such health advantages.

Cassidy said her team will also publish findings in the American Journal of Clinical Nutrition showing that flavonoids found in soy and cocoa appear to have the strongest effects of reducing risk of heart disease.

The next step will organize 150 women volunteers with a specific illness. The researchers will look at whether flavonoids help reduce blood pressure, cut cholesterol levels and improve the condition of blood vessels.

Half the women in the year-long study will eat chocolate containing 30 grams of flavonoids found in soy, cocoa and other fruits and vegetables. The others will get chocolate without the active flavonoids.

“This could help doctors give advice to patients on the type and amount of foods to eat to reduce heart disease risk—and it does not necessarily need to be chocolate,” Cassidy said. “If this trial works we will be able to advise on a whole range of foods. People won't have to go around eating specially designed chocolate.”
