A handful of pistachio nuts twice a day protects the heart and arteries from harm caused by stress in diabetics, scientists found.
Just 150 of the nuts or three ounces a day resulted in people with Type 2 diabetes having more 'relaxed' and less narrower blood vessels, lower blood pressure especially when asleep and less strain on the heart after just four weeks.
The study by Pennsylvania State University said the nuts could reduce risk of heart disease but warned the nuts were not a cure for daily stress.
Professor of biobehavioural health and nutritional sciences Sheila West said: 'In adults with diabetes, two servings of pistachios per day lowered vascular constriction during stress and improved neural control of the heart. Although nuts are high in fat, they contain good fats, fibre, potassium and antioxidants. Given the high risk of heart disease in people with diabetes, nuts are an important component of a heart healthy diet in this population.'The study published in the Journal of the American Heart Association involved two diets with the same number of calories.
