Could eating raisins lower the risk of heart disease?
This is the thinking behind a new U.S. trial comparing the effects of the dried fruit against other popular snack foods, such as biscuits, crisps and chocolate.
Previous research has shown that people who ate raisins and started walking regularly had significant health benefits.
Raisins are rich in potassium, important in regulating blood pressure, and their high fibre content makes them more filling than many other snacks.
They are also a significant source of the antioxidants that interfere with cholesterol absorption and help fight disease.
The U.S. study of 50 patients, which began last month, is being run at the Louisville Metabolic and Atherosclerosis Research Centre.
Patients will be given a handful of raisins or another snack food three times daily.
