New York: Eating tangerines may help protect against heart attacks, diabetes, and obesity, according to new US research.

This is because it contains a substance called Nobiletin, a pigment found in tangerine peel, is ten times more potent than a similar one derived from grapefruit which protects from obesity and metabolic syndrome.

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.

One group had symptoms of illness such as 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. But a second group on the same diet but who were fed Nobiletin showed no similar rise. The substance also protected them from atherosclerosis, the build-up of plaque in arteries, which can lead to a heart attack or stroke.

Eating tangerines could protect against heart attacks, diabetes and stroke as well as staving off obesity
