Red bell peppers
If you thought that citrus fruits are the richest sources of vitamin C, you were wrong. Red bell peppers are champions! One medium-seized red bell pepper packs almost three times more of this vitamin than a Florida orange.
Plus, red bell peppers are excellent sources of beta carotene, an antioxidant our bodies transform into vitamin A.
Many studies suggest that vitamin A is essential in combating the common cold or flu. Also, vitamin A deficiency can lead to respiratory infections, so it’s a good idea to add more sources of this vitamin to your diet.
