AIDS, also known as acquired immunodeficiency syndrome, causes damage to the patient’s own immune system due to HIV infection. Therefore, it is important to pay extra attention to the diet and consume more immune-enhancing foods, such as more vegetables and a high-energy, high-protein diet to strengthen the immune system. High protein foods mainly include colostrum, because colostrum, rich in a variety of immunologically active ingredients, has a good role in maintaining the body’s immune function in a self-stabilizing manner. Collagen, rich in amino acids needed by the body, is the most abundant protein in the human body. Including vitamins, especially vitamin C, which can enhance the body’s ability to resist stress and immunity to the external environment. Foods with relatively high zinc content, including seafood, lean meats, coarse grains and legumes, zinc is important for the regulation of immune function.
