Researchers in Norwich have set themselves an easy challenge: finding 150 women prepared to eat a bar of chocolate a day.

The chocolate is free, and made specially for the trial by a Belgian chocolatier. The intention is to see whether it improves the womens health.

The volunteers must be past the menopause, must suffer from type 2 diabetes, and must already be taking statins to reduce their cholesterol levels. They will also need the approval of their GPs.

Postmenopausal women with type 2 diabetes are usually advised to avoid chocolate. Rich in sugar and fat, it is definitely not part of their recommended diet.

Chocolate is also rich in flavonoids, compounds that have been linked with a reduced risk of heart disease. Chocolate companies have seized on the research some of which they have funded themselves to encourage the belief that chocolate can be good for you.

Until now, few of the trials have met the highest standards of scientific rigour. A team from the University of East Anglia plans to put that right.

The volunteers, all postmenopausal women who are not taking HRT, will be divided into two groups. Half will eat the special chocolate, the other half a normal bar as a placebo. The women will be checked at the start of the one-year trial, and five times during it.

Ultrasound scans will measure the thickness of the wall of the carotid artery, and the total volume of plaque, the material that blocks the arteries in heart disease. Peter Curtis, who is co-ordinating the study, said: The chocolate has three times the amounts of flavonoids you would find in a normal high cocoa chocolate. This has been achieved by a special extraction process that retains the chemicals we think are the important ones.

It tastes, he says, quite nice with a flavour of caramel. Soy has been added to provide an even greater dose of flavonoids.

Aedin Cassidy, Professor of Diet and Health at the university, who is heading the project, said: We hope to show that adding flavonoids to their diets will provide additional protection from heart disease and give women the opportunity to take more control over reducing their risk of heart disease in the future.

Ketan Dhatariya, consultant in diabetes at the Norfolk and Norwich University Hospital, added: If the trial confirms that flavonoids improve the level of protection against heart disease, it could have a far-reaching impact on the advice we give.

Iain Frame, director of research at Diabetes UK, which is funding the trial, said: We certainly dont advise people to start eating a lot of chocolate as its very high in sugar and fat. We would always recommend that people with diabetes eat a diet low in fat, salt and sugar with plenty of fruit and vegetables.

He said that older women with diabetes were five times more likely to develop heart disease.

chocolate, mmmmmm
I don't fit the criteria for Type II diabetes, have high cholesterol or live anywhere near Norwich. :)

Isn't a little bit of dark chocolate every now and then supposed to be good for you?

Yup, something like an ounce a day, I think...I would have to google it to be sure...

I like both.....women & chocolate (milk or dark) :-)

How about chocolate women well have eggs bunnies and santa clauses. So maybe there is a niche.
