Why do walnuts make up the brain?

The reason why walnuts nourish the brain:

The content of arginine in walnut protein is particularly high, reaching protein 174 mg per gram of walnut, which is the highest among nut foods and six times that of protein in milk and fruit. Arginine is a substance with nutrition and many unique physiological and pharmacological effects.

One of its important physiological functions is as a raw material for synthesizing endogenous nitric oxide. As a biological messenger, nitric oxide plays a key role in the physiological and pathological regulation of human cardiovascular, nervous and immune systems, such as maintaining the normal function of nervous system, which can be regarded as a brain tonic (promoting sleep, improving memory and learning ability, etc.). ).

At the same time, walnut also contains α linolenic acid, which can be converted into DHA in the body, and this component is very important for the brain development of infants and young children, and it is also of great significance for the elderly to delay brain aging. Therefore, there is a material basis for the saying that "walnuts make up the brain".
