12 Foods to Boost Your Immune System

5. Broccoli


As mentioned before, broccoli is one of the healthiest vegetables of all. It contains many essential substances like sulforaphane, which activates antioxidants and enzymes in our immune cells. These immune cells prevent free radicals – aggressive substances that damage body cells – from doing their destructive work.

Damaged cells are considered to be the leading causes of many diseases: not only cancer but also ageing diseases such as rheumatism, diabetes and a weak immune system.
