Research supported by the U.S. Department of Agriculture has found that dark purple, blue, and reddish fruits may potentially help to prevent obesity. The reason for this is because the pigments responsible for giving the fruits their rich, dark colors may have healthful qualities, as well.
The pigments, known as anthocyanins, were found to prevent obesity in animals that were fed high fat diets. Over the course of eight weeks, animals that consumed high quantities of fat but were also given water infused with purified anthocyanins extracted from blueberries and strawberries experienced lower weight gains and less body fat than control groups, which were given water only.
