24 Jun 2019 --- Phenols found in the shells of cocoa beans have strong effects on the fat and immune cells in mice, a recent study by the University of Illinois, US, has shown. This may be used to reverse chronic inflammation and insulin resistance, which are issues associated with obesity. The extracted phenolic compounds could be added to foods to boost their nutritional value. In addition to the health benefits, this discovery may help mitigate the waste generated from 700,000 tons of shells discarded annually in chocolate production.
