Cocoa Prevents Colon Cancer

Monday, 30 January 2012 07:19 AM

Not only is chocolate a sweet treat for the stomach, new research suggests that cocoa can help protect against intestinal diseases like colon cancer.

In what they claim is the first study of its kind in relation to intestinal pathologies, a research team out of Spain has concluded that cocoa can act as a defense system for the body by interrupting the cell-signaling pathways involved in cell proliferation, a process which results in the formation of tumors.

Their study also found that a cocoa-rich diet can help increase a natural process known as apoptosis or cell death, in which the body eliminates old, unhealthy cells, to make way for new ones — a "chemoprevention mechanism" that helps ward off cancer advancement.

For eight weeks, researchers fed rats a cocoa-rich diet — 12 percent — and then induced the effects of cancer.

Results showed that the rats that consumed a diet high in cocoa had significantly reduced aberrant crypts, a common manifestation of colon cancer. Crypts are tube-like glands found in the lining of the colon and rectum and, when functioning normally, renew the lining of the intestine and produce mucus.

Scientists also noted an improvement in the rats' antioxidant defenses and a decrease in oxidative damage induced by the carcinogens.

According to the World Health Organization, colorectal cancer is one of the leading causes of death worldwide, and is the fourth most common cancer after lung, stomach, and liver.

Cocoa, a major ingredient of chocolate, is rich in flavonoids and antioxidant properties.

A study published last year in the British Medical Journal also found that high levels of chocolate consumption could be associated with a reduced risk of developing heart disease by up to 37 percent.

The Spanish study was published in the journal Molecular Nutrition & Food Research and announced January 24.
