As the saying goes, there is no smoke without fire. The idea that walnuts supplement the brain is not groundless. Studies have shown that walnuts are rich in fatty acids, which is very beneficial to the healthy development of the brain. Experiments also prove that walnuts can improve the memory of mice.

In the folk, the idea of shape-filling is particularly popular. Walnuts look like brains, with left and right brains, and even folds and folds, which are very similar to human brains. So everyone began to fantasize that walnuts can replenish the brain, and later they became more and more fascinated. "Walnuts can nourish the brain" has almost become an ironclad fact. Many parents also bought a lot of walnuts for their children to replenish their brains, hoping to get a good grade in the exam.

Second, the misunderstanding of "walnut for brain"

First of all, we should explain that it is absolutely unscientific to say that walnuts are brain-nourishing foods. In fact, the brain-nourishing ingredients contained in walnuts are found in most nuts, such as almonds, peanuts, cashews and hazelnuts. Even their content is not as good as walnuts. So the altar of "walnut strengthening brain" was broken.

Secondly, you can't eat more walnuts. Some people eat walnuts crazily in order to be smarter. Walnut oil is high and difficult to digest. Excessive consumption can lead to indigestion and diarrhea.

Third, the function of walnut

Having said so many bad things about walnuts, let's "wash white" it. In fact, people don't have to "wash" it at all. Walnuts have many benefits.

1, improve the digestive system

Walnut contains no cholesterol and is extremely rich in antioxidants such as vitamin A and carotene, so the human body has a high absorption rate; In addition, it can also reduce gastric acid and stimulate bile secretion. And has a good preventive effect on diseases such as gallstones.

2. Improve heart and brain function

Eating walnuts can promote blood circulation and effectively prevent diseases such as hypertension, heart failure and heart disease.

3, skin care and beauty

Walnut is rich in squalene, which has a strong affinity with human skin and can be quickly absorbed by the skin, improving the moisture and elasticity of the skin. In addition, antioxidants such as vitamins A, D, K and E in walnuts can effectively remove skin wrinkles and have miraculous effects on symptoms such as chapped hands and feet.

Summary: In short, as a good ingredient, its efficacy is definitely there, but if it is infinitely magnified, it will lose its rationality.
