Tsuda et al [4] recently provided evidence that anthocyanins
extracted from purple corn, when provided to
mice in tandem with a high-fat diet, effectively inhibited
both body weight and adipose tissue increases. Typical
symptoms of hyperglycemia, hyperinsulinemia, and hyperleptinemia
provoked by a high-fat diet did not occur
when mice also ingested isolated anthocyanins. The experiments
suggest that anthocyanins, as a functional food
component, can aid in the prevention of obesity and diabetes.
