Top 4 in Top 5 Health Benefits of Walnut Oil
Regular consumption of walnuts may reduce high triglyceride, total, and LDL (bad) cholesterol levels in the blood, which otherwise raise the risk of heart disease. This could be because walnuts contain large amounts of antioxidants and omega-3 fatty acids, both of which are also present in walnut oil.
One study demonstrated that taking a daily capsule containing 3 grams of walnut oil for 45 days significantly reduced blood levels of triglycerides relative to baseline values in 60 persons with high triglyceride levels. Based on these findings, consuming walnut oil may help lower your chance of developing heart disease, but additional study is required.
