What can I eat to quickly boost my immune system?

1. Pay attention to daily dietary balance; avoid greasy and overly sugary unhealthy foods, eat more fresh vegetables and fruits to supplement vitamins and dietary fiber. Vitamin C, in particular, can effectively enhance immunity—consume more alkaline fruits such as oranges, grapefruits, and lemons. 2. Eat more seafood, such as mussels, clams, cuttlefish, goldfish, and shrimp, which are rich in high-quality protein and unsaturated fatty acids, as well as various essential elements that help boost the immune system. 3. Increase intake of calcium- and phosphorus-rich foods such as milk, tofu, and soy milk, as both calcium and phosphorus are important elements for enhancing immunity. 4. Consume more cobalt-containing foods such as laver (seaweed), seafood, lean meat, and cuttlefish, all of which are rich in cobalt and help strengthen the body's immune function. 5. Eat more protein-rich foods such as eggs, beef, and lean meat, which can effectively improve the body's immunity and help maintain overall health. 6. Increase consumption of antioxidant-rich foods such as dark-colored vegetables, tomatoes, and egg yolks. These foods are rich in vitamins that combat free radicals in the body, slow aging, and promote good health.
