New findings suggest the consumption of tree nuts may help reduce the risk of cardiovascular disease. The findings were uncovered with the use of a systematic review and meta-analysis of 61 controlled trials. The findings revealed that consuming tree nuts, such as walnuts, lowered total cholesterol, triglycerides, LDL cholesterol and ApoB – the primary protein found in cholesterol. These are all key factors in determining a person’s risk of cardiovascular disease. Walnuts, specifically, were observed in 21 of the 61 controlled trials, more than any other nut.
Author Dr. Michael Falk said, “Our study results further support the growing body of research that tree nuts, such as walnuts, can reduce the risk of cardiovascular diseases. Tree nuts contain important nutrients such as unsaturated fats, protein, vitamins and minerals. Walnuts are the only nut that provide a significant amount (2.5 grams per one ounce serving) of alpha-linolenic acid (ALA), the plant-based form of omega-3s.”
Aside from reducing the risk factors that contribute to heart disease, researchers also found the consumption of walnuts lowered the risk of heart disease in type 2 diabetics.
There is over two decades worth of research that supports walnuts as useful in lowering the risk of cardiovascular disease by reducing the risk factors associated with it – cholesterol, blood pressure and boosting HDL cholesterol. Aside from providing omega-3, walnuts are also a good source of fiber and protein, making them an overall nutritious snack that can improve overall health.
The findings were published in the American Journal of Clinical Nutrition.
