The immune system is your body’s “internal military” protecting you from microorganisms that can make you sick.1 It’s not just one part of the body, but rather a system of cells, tissues and organs that work together to keep you strong.2

When invading microorganisms try to attack, you can fight back if you have a strong immune system.1

Micronutrients

Research suggests that deficiencies in certain vitamins and minerals may impact the immune system.1-3  Being aware of nutrients that support immune health and where they are found can help you incorporate them into your meals.

  • Vitamin C – fruits and vegetables
  • Vitamin E – fruits, vegetables, nuts and seeds, fish6
  • Vitamin B6 – chicken, enriched cereals, nuts, legumes, bananas7
  • Vitamin B12 – chicken, dairy products, fish, fortified non-dairy beverages8
