Description:
Recent studies have suggested that cocoa or dark chocolate may possess certain beneficial effects on human health. This is mainly caused by a particular substance present in cocoa called epicatechin. Cocoa possesses a significant antioxidant action, protecting against LDL oxidation, perhaps more than other polyphenol antioxidant-rich foods and beverages. Some studies have also observed a modest reduction in blood pressure and flow-mediated dilation after consuming dark chocolate daily. Consuming milk chocolate or white chocolate, or drinking fat-containing milk with dark chocolate, appears largely to negate the health benefit. Processed cocoa powder , processed with alkali greatly reduces the antioxidant capacity as compared to "raw" cocoa powder. Processing cocoa with alkali destroys most of the flavonoids.
One-third of the fat in chocolate comes in the forms of a saturated fat called stearic acid and a monounsaturated fat called oleic acid. However, unlike other saturated fats, stearic acid does not raise levels of LDL cholesterol in the bloodstream. Consuming relatively large amounts of dark chocolate and cocoa does not seem to raise serum LDL cholesterol levels; some studies even find that it could lower them. Indeed, small but regular amounts of dark chocolate lower the possibility of a heart attack.
A study performed at the Karolinska Institute in Stockholm and appearing the Journal of Internal Medicine (Sep 2009), found that survivors of heart attacks who ate chocolate at least two or three times a week reduced their risk of death by a factor of up to three times compared to survivors who did not eat chocolate. The benefits were specific to chocolate and not to other sweets.
