Heart Health: Anti-Inflammatory Chocolate Milk or Red Wine?

Red wine for cardiovascular health?  How about chocolate milk?   A new study suggests that regular consumption of skim milk with flavonoid-rich cocoa may reduce inflammation, potentially slowing or preventing development of atherosclerosis. The effect may not be as great as that seen with red wine….but may be a healthy nightcap of a different nature.

Epidemiologic studies have suggested that flavonoid intake plays a critical role in the prevention of coronary heart disease. Because atherosclerosis is considered a low-grade inflammatory disease, some feeding trials have analyzed the effects of cocoa (an important source of flavonoids) on inflammatory biomarkers, but the results have been controversial.

Scientists in Barcelona, Spain, recruited 47 volunteers ages 55 and older who were at risk for heart disease. Half were given 20-gram sachets of soluble cocoa powder to drink with skim milk twice a day, while the rest drank plain skim milk. After one month, the groups were switched.

Blood tests found that after participants drank chocolate milk twice a day for four weeks, they had significantly lower levels of several inflammatory biomarkers, though some markers of cellular inflammation remained unchanged.  They also had higher levels of HDL, otherwise known as the “good” cholesterol.

These results, published in the November issue of the American Society for Clinical Nutrition, suggest that the intake of cocoa polyphenols may modulate inflammatory mediators in patients at high risk of cardiovascular disease. These anti-inflammatory effects may contribute to the overall benefits of cocoa consumption against atherosclerosis.
