Nutrition plays a crucial role in maintaining and supporting a healthy immune system. Here are some key points on how different nutrients contribute to immune function: Vitamin C: Known for its immune-boosting properties, vitamin C helps stimulate the production of white blood cells, which are vital for fighting infections. You can find it in citrus fruits, strawberries, kiwis, bell peppers, and broccoli1. Vitamin D: Adequate levels of vitamin D are essential for immune function. It helps modulate the immune response and can reduce the risk of infections. Sources include sunlight, fatty fish, and fortified foods1. Zinc: This mineral is important for the development and function of immune cells. It can be found in meat, shellfish, legumes, seeds, and nuts2. Antioxidants: Vitamins A and E, along with other antioxidants, protect healthy cells from damage and support the immune system. Carrots, sweet potatoes, spinach, and nuts are good sources2. Protein: Essential for the repair and building of tissues, protein also plays a role in the production of antibodies and immune cells. Lean meats, poultry, fish, beans, and legumes are excellent sources2. Probiotics: These beneficial bacteria support gut health, which is closely linked to immune function. Yogurt, kefir, sauerkraut, and other fermented foods are rich in probiotics2. A balanced diet that includes a variety of these nutrients can help maintain a functional immune system and reduce the risk of infections3. However, it’s important to note that no single food or nutrient can prevent illness on its own
