Eating a handful of nuts daily, particularly tree nuts, may reduce the risk of cardiovascular disease among people with Type-2 diabetes, associated with an increased risk for high cholesterol, heart disease and stroke, say researchers.
Tree nuts such as walnuts, almonds, Brazil nuts, cashews, pistachios, pecans, macadamias, hazelnuts and pine nuts were strongly associated with reduced risk of coronary events, cardiac death and total mortality compared with peanuts.
The results showed that eating even a small amount of nuts had an effect.
While the exact biological mechanisms of nuts on heart health are unclear, researchers noted that nuts appear to improve blood sugar control, blood pressure, metabolism of fats, inflammation and blood vessel wall function.
"Cardiovascular disease is the leading cause of death and a major cause of heart attacks, strokes and disability for people living with Type-2 diabetes," said Prakash Deedwania, Professor at the University of California-San Francisco.
