It's time for Easter eggs, and here are some facts about the main ingredient Chocolate is made from beans harvested from the cocoa tree Theobroma cacao. The cocoa beans are removed from their pod, fermented, dried, roasted and then ground to make cocoa mass. This is then pressed to produce cocoa butter and cocoa cake, which is eventually ground to make cocoa powder. Chocolate contains carbohydrates, fat and protein. The fat in chocolate is mainly made up of stearic and oleic acid. Stearic acid is a saturated fat but, unlike other types of saturated fat, stearic acid doesn't raise the 'bad' cholesterol in our blood. Oleic acid is a monounsaturated fat and has been found to lower the 'bad' cholesterol in the blood. Chocolate contains compounds called flavonoids which have antioxidant properties. They are also present in foods such as berries, red wine and green tea. The more processed the chocolate, the fewer flavonoids it contains. Dark chocolate contains nearly four times as much as milk chocolate, and white chocolate doesn't contain any flavonoids at all. There's growing scientific evidence to show that flavonoids are heart healthy. Several studies have shown that they slow down the processing of 'bad' cholesterol into material that clogs the arteries, and make blood platelets less likely to clump together to cause the clots which lead to strokes and heart attacks. Eating dark chocolate can help lower blood pressure - if you've reached a certain age and have mild high blood pressure. A 2007 study published in the Journal of the American Medical Association looked at the effect of eating 6g of either white or dark chocolate a day for 18 weeks. The subjects were 44 adults aged between 56 and 73. The study found that the group eating dark chocolate saw a drop in their blood pressure while there was no change for the group eating white chocolate. Scientists believe that flavonoids coax the body into making more nitric oxide which help to relax the blood vessels, thus easing blood pressure and helping circulation. Chocolate has other health benefits too. A 2007 study published in the European Journal of Clinical Nutrition found that men who preferred chocolate to other types of sweets and candy had a lower body mass index and waist circumference than men who didn't eat chocolate. And more good news: those who liked chocolate were happier, too.
