Oats
Oats are healthy grains with a high amount of beta-glucan, which is a form of fiber with many antioxidant and antimicrobial properties. Many studies have shown that consuming them frequently would help increase the number of white blood cells, thus boosting your immune system. As a result, they will reduce the risks of suffering from some common bacterial and viral infections such as herpes, flu, or anthrax. In addition, oats can speed up the healing process and boost the effects of antibiotics. Make sure to have at least 1 portion of oats and whole grains on a daily basis. [15]
