Essential vitamins to support our immune system

Our nutritionist Emma ‘Edamame’ has put together some top tips for keeping well, including how to power your immunity through nutrients.

As with any cellular process or system within our body, our immune system also needs nutrients to power it. Theres are lots of micronutrients (vitamins and minerals) that aid our body’s immune system, to help hinder infection, as well as clear infections and repair damage.

The key vitamins and minerals that are essentials for our immune system are vitamins A, C, D, E, B2, B6, and B12, folate, iron, selenium, and zinc.

The great thing is that a number of while foods are rich in these vitamins and minerals. Have a look at our list below to check you’re eating a wide range of these nutrient-rich food.

  • Vitamin A: Orange veggies such as pumpkin, kumara and carrots, red capsicum, as well as egg yolks and dark leafy greens.
  • B vitamins (including folate): whole grains, legumes, nuts and seeds, meat, dairy, eggs, leafy greens, fruit and vegetables*.
  • Vitamin C: red capsicums, citrus fruits, broccoli, kale and Brussels sprouts.
  • Vitamin D: canned tuna, oily fish, eggs and whole grains.
  • Vitamin E: nuts and seeds, avocado.
  • Zinc: shellfish, nuts and seeds, chickpeas, peanuts, pumpkin seeds and beef.
  • Selenium: brazil nuts, fish, eggs, whole grains and legumes. You can get all the selenium you need in one day from one brazil nut. It is recommended to eat no more than 3 brazil nuts each day.
  • Iron: shellfish and fish, red meat, whole grains, legumes, broccoli, spinach and dried fruit.
  • Macronutrients such as proteins, carbs and fats also play a role in immune function or nutrient absorption, so eating a healthy, balanced diet is important.

*All different B vitamins have differing food sources. Be sure to check out the NZ Nutrition Foundation website for more details.
