There is a reason why vitamin C is recommended when someone has caught a cold. That is because it helps to build the immune system. It does this by increasing the production of white blood cells needed to fight of infections. The body is not capable of making vitamin C on its own. Therefore, it is important to include vitamin C-rich foods in your daily diet. Eat citrus foods such as grapefruit, oranges, tangerines, lemons, watermelon, and limes among others.
