Lead by researchers at Brigham and Women’s Hospital in Boston and Fred Hutchinson Cancer Research Center in Seattle, the study will be the first large test to evaluate cocoa flavanols, which in previous, smaller studies improved blood pressure, cholesterol, the body’s use of insulin, artery health and other heart-related factors.
The study will also evaluate the use of multivitamins to help prevent cancer. Recent research suggested this benefit but involved just older, unusually healthy men . One commentary went so far as to call multivitamins a “waste” of money after finding little health benefits for most adults .
The study will be sponsored by the National Heart, Lung and Blood Institute and Mars Inc., maker of M&M’s and Snickers bars. The candy company has patented a way to extract flavanols from cocoa in high concentration and put them in capsules. Mars sells cocoa extract capsules under the brand name CocoaVia, but with less active ingredient than those that will be tested in the study. In most candy on the market today, cocoa flavanols are destroyed by processing.
