Winter diet should be based on the principle of preserving yin and latent yang
Kidney water is strong in winter, salty food belongs to water, and the heart belongs to fire. Eating more salty food can help water overcome fire and make the heart suffer from diseases.
The heart is of a bitter nature, so eat more bitter foods to keep the heart and kidneys connected.
After getting up in winter, you can drink hot drinks first, such as cheese, lotus seeds, longan and jujube soup, to benefit the heart and spleen;
Due to reduced activities in winter and human body metabolism slowing down, the elderly should not eat too much. After eating, they can rub their abdomen and walk slowly to help digestion.
