Chocolate: A cure for cancer?

It tastes much too good to be a health food. But can chocolate really prevent cancer, heart disease and depression?

Ever since the Atkins Diet revival made sugar public enemy No 1, confectionery manufacturers have had their work cut out to sweeten up their image. It hasn't been easy: sugar doesn't just make you fat, and thus can contribute to the development of adult-onset diabetes, it also rots your teeth. Willy Wonka would be weeping into his top hat.

But recently, chocolate has been undergoing something of a rehabilitation, and the current thinking is that it may actually be good for you. So, what's going on?

In fact, the idea of chocolate as a health tonic goes back centuries. Long before goji berries, broccoli and tomatoes were hailed as "superfoods", cocoa and chocolate were celebrated as natural remedies. Cocoa and its derivatives have, historically, been prescribed for a range of ailments, including liver disease and kidney disorders, and by the 1600s, chocolate was identified as a mood enhancer.

It is only relatively recently that chocolate fell out of favour with the health lobby. Although cocoa is rich in flavonoids (which promote healthy cellular tissue), the practice of mixing it with saturated fat, cholesterol and sugar made it less friend, more foe. But now chocolate has been thrown a lifeline: antioxidants. An antioxidant is something that slows down, or prevents, the oxidation of cells; oxidation produces free radicals, which damage cells and can lead to heart disease and cancer. The flavonoids in dark chocolate (containing 70 per cent or more cocoa solids) act as antioxidants, and it contains almost five times the flavonol content of apples (though they also have fibre and vitamins). The industrial processes that turn cocoa into chocolate reduce its antioxidant properties, which is why the less-processed dark chocolate has more antioxidants.
