Cholesterol Improvement, Daily consumption of walnuts has a positive effect on cholesterol levels, without increasing body weight. Studies found that after 1 year of adding a handful of walnuts to your daily diet significantly lowers levels of LDL cholesterol compared to those those consuming their usual diet.
Blood Sugar Management
Research has also demonstrated that walnut oil can help to regulate blood sugar levels making it suitable for people with diabetes or pre-diabetes. According to studies, walnut oil can help reduce blood sugar levels while also increasing the body’s production of insulin. In conclusion, we showed that addition of 15 ml walnut oil to previous diet of diabetics, for 90 days, significantly decreased the total cholesterol, LDL cholesterol, triglyceride and total cholesterol to HDL ratio, which are all important in management of diabetes. It can be hypothesized that these effects may have an impact on reduction of CAD risk of and other disease-related complications in diabetic patients. Additionally, walnut oil may serve as a helpful natural remedy in hyperlipidemic patients with type 2 diabetes.
According to research, walnut oil is also excellent for your heart. Walnut oil contains no cholesterol and is full of healthy polyunsaturated fats and monounsaturated fats. Studies have found that its nutritional make up can help reduce cholesterol levels and blood pressure while improving the circulation of blood around the body. Because of these effects, walnut oil could help reduce the risk of heart attack, stroke and atherosclerosis. Frequent consumption of walnuts and/or walnut oil (which typically is how walnut products are consumed) may improve cardiovascular risk via mechanisms that extend beyond their established cholesterol-lowering action. The cardio-protective benefits of walnut oil are primarily due to the high concentration of alpha-linolenic acid (ALA), which is an omega-3 fatty acid that ultimately is converted to eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), and omega-3 fatty acids that are easily utilized by the body. A study published in the American Journal of Clinical Nutrition reported that one tablespoon of walnut oil provides 1.4 grams of ALA. Men require 1.6 grams and women 1.1 grams of ALA per day. Walnuts differ from other nuts because they primarily consist of omega-3 fatty acids whereas monounsaturated fats are found in higher levels in most other types of nuts.
