Foods that support a healthy immune system include those rich in vitamins and minerals. Fruits and vegetables, especially citrus fruits, bell peppers, and leafy greens, are excellent sources of vitamin C, which boosts immune function. Foods high in zinc, such as nuts, seeds, and legumes, promote healing and immune cell production. Incorporating probiotics from yogurt or fermented foods can improve gut health, further enhancing immunity. Additionally, consuming omega-3 fatty acids found in fatty fish may reduce inflammation, supporting overall immune response.
