Fruits are also a great source of vitamins and minerals. The daily intake of fruits will increase the immunity against diseases in the long run. Citrus fruits such as oranges and lemon have vitamin C in very high amounts. Vitamin C helps in building up immunity system naturally and acts as an antioxidant.

Almonds, apricots, Brazil nuts, cashew nuts, pistachios, pecans, dried cranberries, raisins, and pumpkin seeds are also high in vitamins such as vitamin A, vitamin E, vitamin K, calcium, iron, and copper. As mentioned earlier, these micronutrients are needed for maintaining and improving immunity.
