Eating grapes could reduce heart disease and diabetes, scientist claim.

The fruit lowered blood pressure, improved heart function and reduced other risk factors for heart disease and metabolic syndrome, it was claimed.
American researchers found this could be due to phytochemicals – naturally occurring antioxidants – that grapes contain.
Following animal tests, the research revealed a grape-enriched diet preventing risk factors for metabolic syndrome, a condition which is often a precursor to type 2 diabetes.

Mixing a blend of green, red and black grapes into the diets of laboratory rats as part of a high-fat, American style diet, they were compared with a test group fed with a similar diet full of fat and sugars.
After three months, the rats that received the grape-enriched diet had lower blood pressure, better heart function, and reduced indicators of inflammation in the heart and the blood than rats who received no grape powder.
Rats also had lower triglycerides and improved glucose tolerance.
Heart surgeon Dr Steven Bolling said: "The possible reasoning behind the lessening of metabolic syndrome is that the phytochemicals were active in protecting the heart cells from the damaging effects of metabolic syndrome.
"In the rats, inflammation of the heart and heart function was maintained far better.
"Although there's not a particular direct correlation between this study and what humans should do, it's very interesting to postulate that a diet higher in phytochemical-rich fruits, such as grapes, may benefit humans."
Although he added those wanting to lower blood pressure and reduce the risk of diabetes should follow some tried-and-true advice such as eating a healthy diet low in saturated fat, trans fat and cholesterol, maintain a desirable weight and exercise more.
The findings are published at the Experimental Biology convention in California.
