You can eat it at any time of the day.

Insist on eating walnuts every day.

Chinese medicine has called walnuts "longevity fruit" since ancient times, and holds that walnuts can tonify the kidney and brain, tonify the middle energizer, and nourish the skin and blacken the hair. Zhang said that walnuts are most suitable for mental workers, especially white-collar women, because these people often overuse their brains and consume sad blood. Eating walnuts regularly can replenish the brain, improve brain circulation and enhance brain power. At the same time, it also has the effect of blackening hair and moistening skin. Because "hair is bleeding" and blood is black, walnuts are rich in vitamins, which can improve the physiological activity of human skin, so they are beautiful products for women.
