More on the Benefits of Cocoa1
Cocoa contains large amounts of polyphenols, in particular a sub-class call flavanols or flavan-e-ols. It is the flavonols in cocoa that give it the bitter taste found in dark chocolate. The main flavanols are catechin and epicatechin which give cocoa its antioxidant properties.
In addition to their antioxidant activity, cocoa increases the levels of nitric oxide. Nitric oxide acts to cause dilation of arteries and prevents leukocyte adhesion and migration, smooth muscle cell proliferation and platelet adhesion and aggregation. Low nitric oxide levels leads to hardening of the arteries and increased risk of cardiovascular disease.
In the last ten years, several studies have been done with patients who have cardiovascular disease, diabetes and no disease. Those eating the highest levels of cocoa had significant lower levels of all-cause mortality, cardiac death, cardiovascular disease, heart failure, heart attack, stroke and diabetes. One of the thoughts of how cocoa reduces the risk of cardiovascular problems is by reducing the inflammatory response within the body which that leads to the development of these diseases.
The adhesion of platelets can also contribute to the increase risk of cardiovascular disease. A review of twenty-five studies which looked at the effects of polyphenol-rich foods showed that cocoa was the only food with consistently positive finding of inhibiting platelet aggregation.
Although there have been few human studies there is evidence that cocoa may reduce insulin resistance. Insulin resistance is known to lead to type II diabetes. This benefit may be a result of either antioxidant or nitric oxide properties of cocoa.
There is promising preliminary evidence for decreased inflammation of nerves(as in Parkinson’s disease), improved cerebral blood flow(important in memory function and in preventing dementia and stroke), and protection of neurons ( a factor in stroke and Alzheimer’s disease).
Because of the antioxidant properties of cocoa, redness of the skin may be prevented when exposed to sunlight and improvement of microcirculation occurs when cocoa is ingested.
Obesity may also benefit from the ingestion of cocoa or chocolate in small amounts, they do not cause weight gain. The increase of nitric oxide improves the uptake of glucose and inhibits fat synthesis. It has also been shown that just the smell of chocolate can suppress the appetite.
