Admit this, we all hate diseases, be it the seasonal flu, diarrhea, or a chronic disease such as asthma. Having a strong immune system can help prevent those likely visits to the GPs and pharmacies.

The question is, how to boost the immune system naturally?

Immune boosting foods

Citrus fruits:

These fruits contain vitamin C that is important for the immune system of our bodies. Citrus fruits are therefore considered as one of the best immune system foods.

We need vitamin C to energize and support our immune system. It is embedded right within the immune cells, and the amount of this vitamin is closely related to the activity of these cells. Research has shown low levels of vitamin C in multiple disease cases. Fortunately, we can add more citrus fruit to our diet to get the required levels of vitamin C. Here’s a list of citrus fruits that serve as natural immune boosters:

  • Orange
  • Lemons
  • Lime
  • Grapefruit
  • Tomatoes
  • Clementines

Note that human body does not synthesize vitamin C and whatever amount of C vitamin we eat in the form of food, it is not stored for future use. Therefore, we need a regular supply of this vitamin. Add citrus fruits to your regular diet to prevent vitamin C deficiencies and to improve your immune system.
