Description Health benefits of walnuts and how much you should eat 1. Heart health Walnuts are a great source of alpha-linolenic acid (ALA), an omega-3 fatty acid that is important for reducing inflammation. In fact, it is the only nut significantly high in these omega-3 fatty acids. Their anti-inflammatory compounds may reduce the risk of heart disease. 2. Brain health Studies have shown that the antioxidants and anti-inflammatory polyphenols (compounds) found in walnuts may improve brain function and slow mental decline that occurs with aging. Cognitive functions include your memory and ability to think. 3. Gut health Bacteria and microbes in your intestines and gut are also essential to your health. Research shows walnuts can improve gut health. In a clinical trial, adults who ate walnuts every day had healthier gut bacteria. 4. Cancer prevention Microbes in your gut take compounds found in walnuts and produce urolithin compounds. These urolithins may help lower risk for certain cancers. Research is still being done to fully understand walnuts’ potential role in cancer prevention. How many walnuts should I eat? The 2020-2025 Dietary Guidelines for Americans recommends about 5 ounces of nuts, seeds and soy products per week for a 2,000 calorie diet. One serving (1 ounce) contains 2 grams of fiber, 4 grams of protein, 18 grams of fat, and about 190 calories. What nutrients do walnuts contain? Although walnuts are high in calories, they are also high in nutrients. The healthy unsaturated fats in walnuts keep you feeling full for longer. Recent research suggests that the way fat is stored in walnuts prevents your body from holding onto all the calories. One study found that even though an ounce of walnut has 190 calories, only about 145 are usable. Walnuts also give you some of the iron and magnesium you need – about 10-14% of your daily needs. What are the best ways to eat walnuts? To maximize the health benefits, look for raw, unsalted walnuts. You can eat them alone as a snack or add them to your oatmeal in the morning. While walnuts have plenty of health benefits, it’s still important to not overeat.
