1. Benefits

1.1 Enhancing Brain Function

Walnuts are rich in nutritional value and contain various trace elements such as manganese and zinc, which are essential components of the human pituitary gland. Eating walnuts in moderation can supplement the brain's nutrition and enhance the vitality of brain cells, thereby promoting brain health and intelligence.

1.2 Improving Bowel Movements

The oil in walnuts has a laxative effect, promoting intestinal health. It is commonly used as an adjuvant therapy for dry stool and constipation in special populations such as elderly individuals and those with weak physical constitutions.

1.3 Protecting Cardiovascular Health

Walnuts are rich in unsaturated fatty acids, such as linoleic acid glycerides and oleic acid glycerides, which can promote the decomposition and metabolism of fatty acids and cholesterol in the human body, preventing their accumulation in the blood vessels. The abundant vitamin E in walnuts can also help reduce blood cholesterol levels. Therefore, eating walnuts has a protective effect on cardiovascular health.

2. Drawbacks

Walnuts are high in fat and have a high energy density. Eating a small amount of walnuts has minimal impact on the body, but excessive consumption may increase the risk of obesity. Therefore, it is not advisable to consume too many walnuts at once.
