Nutritional strategies to support immune function include an emphasis on consuming a variety of fruits and vegetables rich in vitamins and minerals, particularly vitamin C, vitamin D, zinc, and antioxidants. Incorporating fermented foods like yogurt and kimchi can enhance gut health and, consequently, the immune system. Staying hydrated and consuming adequate protein also play significant roles in maintaining immune health. Furthermore, limiting processed foods and added sugars supports overall well-being and a robust immune response.
