Tangerines 'a tonic for your heart'

We all know how an apple a day is supposed to keep the doctor away – now it seems the same is true for tangerines.

According to research, eating the fruit could protect against heart attacks, diabetes and stroke as well as staving off obesity. Nobiletin, a pigment found in tangerine peel, is ten times more potent than a similar one derived from grapefruit.

Researchers from the University of Western Ontario, in Canada, fed two groups of mice a diet high in fats and simple sugars, reports the journal Diabetes.

The first group became obese and showed signs related to metabolic syndrome – elevated cholesterol and triglycerides, high blood levels of insulin and glucose and a fatty liver – all of which increase the risk of diabetes and heart disease. However the second group, which had Nobiletin added to its food, gained a normal amount of weight and showed no rise in cholesterol, insulin or glucose.
