It is a wide belief that walnuts, when consumed in whole form, provide several nutritional benefits. Consumption of walnuts has previously been associated with improved brain health, skin and body.
Now, a new study conducted by researchers at the Life Sciences Research Organization suggests that tree nuts, including walnuts, can help reduce the risk of cardiovascular diseases.
According to the study published in the American Journal of Clinical Nutrition, tree nuts help reduce LDL cholesterol, triglycerides and total cholesterol. In addition, it helps control the main protein in LDL cholesterol, called ApoB.
During the study, the researchers conducted a meta-analysis and systemic review of 61 controlled trials. Apart from other tree nuts, the effect of walnuts on cardiovascular health was studied in 21 out of 61 trials. The investigators noted the key health factors that indicate cardiovascular disease risks in an individual.
"Tree nuts contain important nutrients such as unsaturated fats, protein, vitamins and minerals. Walnuts are the only nut that provides a significant amount (2.5 grams per one ounce serving) of alpha-linolenic acid (ALA), the plant-based form of omega-3s," said Dr. Michael Falk, in a press statement.
According to the researchers, the study results show that in addition to lowering the cholesterol, consumption of tree nuts also helps cut down the risk of a heart disease in people who suffer from type 2 diabetes.
A number of factors contribute to an increased risk of heart disease and cardiovascular disorders. Some of these factors include bad arterial function, inflammation and increased diastolic blood pressure, bad (LDL) cholesterol and total cholesterol. The recent study claims that consumption of two servings (two ounces) of tree nuts in a day can help manage all the factors and lower the heart disease risk.
