To support a healthy immune system, foods rich in vitamins and minerals, especially vitamins C, D, and zinc, are essential. Fruits like oranges and strawberries, vegetables such as spinach and bell peppers, along with nuts, seeds, and legumes, contribute vital nutrients. Probiotic-rich foods like yogurt and fermented items enhance gut health, positively influencing immune function. Additionally, consuming lean proteins and whole grains provides the necessary energy and nutrients essential for maintaining optimal health and supporting the body's defense mechanisms.
