Nutrients in the Vegan Diet

For a good overview, see Nutrients in the Vegan Diet – from the Vegan Society UK, and Plant-Based Diet – from the Irish Nutrition & Dietetics Institute.

Vitamin B12:

  • Many meat and dairy products contain high amounts of vitamin B12 because animals accumulate this bacterial product during their lives, and livestock are often supplemented with vitamin B12 in their feed.
  • While there is some evidence that B12 can be produced by plants, fortified foods and supplements are currently the only proven reliable sources for vegans.
  • Vegan Vitamin B12 supplements are made from cultured bacteria, and can be purchased from health shops and online.
  • The Vegan Society sells a supplement called VEG 1 and Vegetology sells a range of supplements suitable for vegans.
  • Some fortified foods also contain B12 such as plant based milks, vegan spreads, nutritional yeast flakes, yeast extracts and breakfast cereals.
  • Read more about B12 here.

Protein:

  • Good sources of protein include beans, lentils, chickpeas, tofu, soya milk, soya yoghurt and peanuts.

Calcium:

  • 400ml of calcium-fortified plant milk – just under two cups – provides roughly two thirds of an adult’s recommended daily intake of calcium.
  • 100g of calcium-set tofu (uncooked) can provide half of an adult’s daily needs.
  • Other useful sources of calcium include kale, watercress, okra, tahini, dried figs, haricot beans and almonds.
  • Plant-based sources of calcium – from the Irish Nutrition & Dietetics Institute.

Vitamin D:

  • Taking in sufficient amounts of vitamin D can be difficult, even for people who aren’t vegan. One study found that 41% of Americans may be deficient in vitamin D.
  • Sunshine is a good source of Vitamin D. As Irish people do not get much sunshine apart from the summer months, supplementation is recommended for everyone, not just vegans.
  • Vitamin D3 in supplements is often sourced from Lanolin (sheep’s wool). However, vegan D3 supplements (made from lichen or Vitamin D2) are also available.
  • Mushrooms contain Vitamin D2.

Iron:

  • Good plant sources of iron include lentils, chickpeas, beans, tofu, cashew nuts, chia seeds, ground linseed, hemp seeds, pumpkin seeds, kale, dried apricots and figs, raisins, quinoa and fortified breakfast cereal.

Omega 3 and 6:

  • Plant-based sources include chia seeds, ground linseed, hemp seeds, walnuts and rapeseed oil.
