LONDON (Reuters) - Calling all chocoholics: British researchers recruiting volunteers willing to eat a bar of chocolate daily for a year, guilt-free and all in the name of science.

The trial starting in June will explore whether compounds called flavonoids found in chocolate and other foods can reduce the risk of heart disease for menopausal women with type 2 diabetes, the researchers said on Monday.

Previous studies have suggested dark chocolate is rich in the beneficial compounds 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.
