Are Walnuts Good for the Brain?
Walnuts contain important phytochemicals as well as high amounts of polyunsaturated fats which do offer potential benefits for both brain health and brain function. Omega-3 plays a part by helping to reduce oxidative stress in the brain, but also by helping to improve brain signalling and neurogenesis, which is the creation of neurons.
1. May Promote Heart Health
Due to the high levels of omega-3 fatty acids, walnuts are very beneficial to the cardiovascular system. Eating a few walnuts a day may help reduce blood pressure too. Omega-3 fatty acids are known to reduce bad cholesterol in the body and encourage the production of good cholesterol. They also help reduce inflammation and boost blood vessel function. As a consequence, walnuts can promote heart health.
2. May Reduce Cancer Risk
Walnut powder is rich in plant compounds like omega 3-fatty acids, polyphenols, and urolithins. These bio-active components may have anticancer properties.
Walnut powder may reduce the risk of certain types of cancers such as that of breast, colon, and prostate. The American Association For Cancer Research stated that consuming a few walnuts each day may help reduce the risk of breast cancer.
3. Weight Management
In trials that compared weight loss using diets that include or exclude nuts, the diets that included nuts in moderation showed greater weight loss.
4. May Boost Immunity
Walnut powder contains antioxidants that keep your immune system healthy and prevent the onset of diseases. Add some walnuts to your diet every day.
Walnuts are rich in vitamins and minerals such as copper and vitamin B6 that may boost immunity.
5. Walnuts are High in Protein
Protein is one of three macronutrients your body needs to thrive (carbohydrates and fats are the other two). Incorporating protein into your diet not only helps your body rebuild its tissues, but it also triggers feelings of satiety. This means that you will not be reaching for an unhealthy snack just an hour after your meal.
Walnuts are an excellent source of protein, containing 4 grams of protein per ounce (Self Nutrition Data, n.d.). Although walnuts are not a complete protein, they contain many of the essential amino acids your body requires. The protein in walnuts is broken down into these component amino acids, which are then used to support physiological processes such as muscle repair.
Walnuts For Healthy And Beautiful Skin
6. May Delay Skin Aging
Walnuts can be good for the skin as they are packed with the B-vitamins. These vitamins may help ease stress and hence mood. Lower stress levels may promote skin health, though more information is warranted in this regard. Increased stress levels may lead to an earlier onset of wrinkles and other signs of ageing.
The vitamin E (a natural antioxidant) in walnuts may help fight the free radicals caused due to stress. This can further help delay the ageing process.
7. May Help Moisturize Skin
Applying warm walnut oil may help ease dry skin. Anecdotal evidence suggests that walnut oil may help keep skin moisturized. It may nourish skin from within.
8. May Reduce Dark Circles
Regular application of warm walnut oil may lighten dark circles. The oil could soothe the skin. It also may ease puffiness and relax your eyes. However, there is no direct research in this regard.
