Tonifying in winter can store the energy transformed by nutrients in the body, thus strengthening the body resistance and strengthening the body resistance. Tonic food is the best. Neijing says "nourishing yin in autumn and winter", while the northern winter climate is dry and windy. Therefore, nourishing yin essence is an important part of health preservation in winter.

You can eat more nuts, such as walnuts, hazelnuts, pine nuts and chestnuts. You can add some Radix Adenophorae, Radix Astragali and Radix Ophiopogonis to porridge and soup, but you don't need too much, because after all, it is a food supplement rather than a medicine supplement.
