According to a study, having two-three servings of tree nuts such as walnuts everyday can reduce risk of cardiovascular diseases. Lead researcher of the study Michael Falk from the Life Sciences Research Organisation in the U.S. said that consuming tree nuts reduces total cholesterol, LDL cholesterol and triglycerides. Tree nuts have unsaturated fats, vitamins, minerals and protein.
Falk further added that walnuts are the only nut that provide significant amount of alpha-linolenic acid, a plant-based form of omega-3 fatty acids. More than any other nut that were reviewed in the study, walnuts seemed to have been investigated in 21 of the 61 trials.
Researchers came to the conclusion that eating at least two servings daily of tree nuts tended to have stronger effects on the total cholesterol as well as LDL levels and that it may particularly be important for lowering risk of heart diseases in people suffering from type 2 diabetes.
Research done over two decades has shown that walnuts can help to lower cardiovascular risk factors by decreasing blood pressure and LDL cholesterol. Apart from providing sufficient amount of omega-3 fatty acids, walnuts also provide a consistent supply of protein as well as fibre.
The study was published in the American Journal of Clinical Nutrition.
