Fight weight gain
A 2011 study from Western University in London, Ont., shows that nobiletin, a flavonoid that is extracted from tangerines, helps to prevent obesity and offers protection against type 2 diabetes. The study looked at mice that were fed a diet high in fat and simple sugars. One group became obese and developed the metabolic signs that increase type 2 diabetes risk.
A second group, fed the same diet but with added nobiletin, gained weight normally and showed no changes in their glucose or insulin levels.
