Theanine can also mobilize the body’s immune cells to defend against viruses, bacteria and fungi. 8, supplemental vitamins Vitamin C can inhibit the synthesis of carcinogenic dietary nitrosamines, as well as promote the formation of antibodies, enhance the phagocytosis of white blood cells, and enhance the body’s ability to resist. Strawberries, tomatoes, cucumbers, carrots and other fruits and vegetables that contain a lot of vitamin C can be eaten. Vitamin A has a protective effect on the mucous membrane of the respiratory tract and gastrointestinal tract.
