Our mothers have taught us to drink lemonade when we catch a cold, and they were more than right! Lemons are other citrus fruits like grapefruit, limes, oranges, tangerines, or clementines are good sources of vitamin C, and probably the tastiest immune-booster out there.
It’s essential to remember that our bodies are unable to store or produce vitamin C, so, in order to maintain your immune system in tip-top shape, you should consume citrus fruits every single day.
Important info! There’s virtually no evidence that vitamin C is effective against COVID-19, but, when it comes to strengthening our immune system, it’s the best!
If you prefer supplements, do not take more than 2,000 milligrams per day.
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.
