A strong immune system is important to maintain one’s health. While there is no magical cure against infections, building immunity can help prevent several illnesses, or recover faster. Adding a variety of foods rich in antioxidants, vitamins, and minerals to one’s meals can help strengthen the immune system to fight off infection-causing pathogens. Here are 16 foods that can enhance immunity and help prevent illnesses. Red bell peppers Red bell peppers are one of the richest sources of vitamin C. A 100-gram serving of red bell pepper contains about 127.7 mg of vitamin C, which is 159 percent of one’s recommended daily intake. They are also a rich source of beta-carotene, which is converted into vitamin A. Due to their high vitamin content, red bell peppers are excellent for boosting immunity. Moreover, vitamin C helps keep skin healthy, while vitamin A contributes to healthy skin and eyes. Blueberries Blueberries contain a particular flavonoid called anthocyanin. This has potent antioxidant properties, which help strengthen the immune system, especially in the respiratory tract. According to studies, those who consume a healthy dose of flavonoids regularly are less likely to develop an upper respiratory tract infection in comparison to others. Broccoli A popular superfood, broccoli is packed with vitamins A, C, and E, fiber, and antioxidants, which help fortify immunity.
