Since ancient times, walnuts have been a symbol of the thinking mind, since the shape of the kernel inside the walnut shell looks like a miniature version of the human brain. Aside from their curious appearance and excellent taste, walnuts are very rich in valuable and healthy nutrients. Let’s take a closer look at the health benefits of walnuts.
Walnuts are very rich in healthy omega-3 fatty acids and monounsaturated fatty acids and a particular good source for linoleic acid and alpha-linolenic acid (ALA). By adding these fatty acids to your diet, they help in lowering both the total and LDL cholesterol and help increase HDL, the good cholesterol in the blood. Studies have shown that monounsaturated fatty acids and omega-3 fatty acids can decrease the risk of coronary artery disease.
The healthy fatty acids contained in walnuts are also having anti-inflammatory properties and they help to keep the blood pressure down.
Walnuts are rich in antioxidant activity and polyphenols, along with melatonin, ellagic acid, vitamin E and carotenoids. These nutrients are thought to be beneficial against inflammation, to help prevent neurological diseases and to slow down the aging process.
Walnuts contain big amounts of vitamin E, which is a powerful antioxidant by itself. Vitamin E is essential for proper function of cell and mucus membranes and has a rejuvenating effect on the skin, since it protects it from free radicals.
Walnuts are very rich in beneficial B vitamins like riboflavin, niacin, thiamin, pantothenic acid, vitamin B6 and folates and they contain a plethora of valuable minerals such as manganese, copper, calcium, iron and zinc. These minerals and vitamins are promoting healthy growth, aid digestion and provide many more benefits for a healthy body.
