Eating broccoli could reverse the damage caused by diabetes to heart blood vessels, research suggests.

A University of Warwick team believe the key is a compound found in the vegetable, called sulforaphane.

It encourages production of enzymes which protect the blood vessels, and a reduction in high levels of molecules which cause significant cell damage.

Brassica vegetables such as broccoli have previously been linked to a lower risk of heart attacks and strokes.

A recent study shows that mediterranean diet that is rich in fruits and vegetables, cooked in olive oil, may prevent Type 2 Diabetes by up to 83%. The finding is, however, from just a preliminary study as more studies need to be done with larger groups of people.

The finding is not surprising as olive oil is already known to help reduce blood sugar and lower blood pressure.
