Vitamin C is an important antioxidant that plays a critical role in immune function. It helps to stimulate the production of white blood cells, which are essential for fighting off infections. Here are some excellent sources of vitamin C:

  • Citrus fruits (oranges, lemons, limes, grapefruits)
  • Bell peppers (red, green, yellow)
  • Strawberries
  • Kiwi
  • Papaya
  • Pineapple
  • Mango

Foods high in Zinc for the immune system:

Zinc is a mineral that is essential for the proper functioning of the immune system. It helps to support the integrity of the immune system’s barriers (e.g., skin and mucous membranes) and is involved in the production of immune cells. Here are some excellent sources of zinc:

  • Chicken (dark meat)
  • Beans (chickpeas, kidney beans, lentils)
  • Nuts (cashews, almonds, peanuts)

Foods high in Probiotics for the immune system:

Probiotics are live bacteria and yeasts that are beneficial for gut health and overall immunity. They help to maintain a healthy balance of gut bacteria, which is essential for immune function. Here are some excellent sources of probiotics:
