Having two-three part of tree nuts such as walnuts daily can reduce the risk of cardiovascular illness.
Consuming tree nuts reduce total cholesterol, triglycerides and LDL (bad) cholesterol, said lead researcher Michael Falk from the Life Sciences study Organisation in the US.
Tree nuts contain important nutrients such as unsaturated fats, protein, vitamins and minerals.
Walnuts are the only nut that supply a significant amount of alpha-linolenic acid (ALA) – the plant-based form of Omega-3s.
More than any other nut observe in this study, walnuts were investigated in 21 of the 61 trials.
The study found that destroy at least two parts (60 grams) per day of tree nuts has stronger impact on total cholesterol and LDL and may be particularly important for lowering the risk of heart illness in individuals with Type 2 diabetes.
More than two decades of study has shown that walnuts may help reduce cardiovascular risk factors by lower LDL cholesterol and blood pressure.
In addition to Omega-3s, walnuts also deliver a convenient source of fibre and protein, said the study revealed in the American Journal of Clinical Nutrition.
