01 Walnuts: "The Fruit of the Brain"

Walnuts are rich in phospholipids, which are an important part of brain tissue and can enhance the brain's memory and thinking ability.
DHA is an important substance that makes up the neuromembranes of the cerebral cortex. It can maintain the integrity of brain cell membranes, and has the effect of promoting brain development and improving memory.
3. Vitamin E – anti-aging
The antioxidant effect of walnuts is due to the vitamin E they contain.
Free radicals will damage healthy cells in our body, so that the body's immunity, cell activity will decrease, wrinkles and stains will also appear. Vitamin E is a free radical scavenger that can protect cells from oxidative damage caused by free radicals, prolong cell lifespan and slow down aging.

Studies have found that walnuts can increase the amount of melatonin secreted by the body by 3 times, which helps improve sleep.
5. Pyruvate - adjuvant treatment of cholelithiasis
The pyruvate contained in walnut kernels can prevent the binding of mucin to calcium ions and unbound bilirubin, and can dissolve, subside and excrete. Patients with cholelithiasis may wish to eat some walnuts to assist in treatment.

Potassium can prevent the increase in blood pressure caused by excessive salt intake, and has a more obvious antihypertensive effect on mild hypertension; Manganese can maintain normal glucose metabolism and fat metabolism in the human body; Chromium has the function of promoting glucose utilization, cholesterol metabolism and cardiovascular protection.
