A balanced diet can help regulate the immune system by supplementing with certain nutrients. In your daily diet, pay special attention to the following types of food:

1. Consume adequate amounts of high-quality protein, such as eggs, fish, lean meat, and soy products, which are the basic building blocks of immune cells.

2. Eat more fresh fruits and vegetables: especially citrus fruits, kiwis, green peppers, and dark green vegetables, which are rich in vitamin C and help fight oxidation.
3. Supplement with probiotics: Yogurt and fermented foods may have a positive effect on maintaining the balance of gut microbiota, and gut health is closely related to immunity.
4. Pay attention to zinc and vitamin D: Nuts and seafood contain zinc, and moderate sun exposure or consumption of egg yolks and liver can supplement vitamin D. Both support the normal functioning of the immune system.
It's important to note that food cannot replace medication. It is recommended that you first determine the cause of your illness and receive standardized treatment under the guidance of a doctor. In addition, maintaining a diverse diet, regular sleep patterns, a positive mood, and avoiding known allergens are all helpful in maintaining bodily stability.
