阅读理解 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.”1.What is the best title for the passage?A.Volunteers wanted for chocolate study.
