Vegetarian and vegan diets - The vegan diet

NHS ChoicesFeature

NHS Choices Logo

A vegan diet contains only plants, such as vegetables, grains, nuts and fruits, and foods made from plants.

Vegans don't eat foods that come from animals, including dairy products and eggs.

Healthy eating

You should be able to get most of the nutrients you need from eating a varied and balanced vegan diet. 

A healthy vegan diet contains:

See the eatwell plate for more information about a healthy diet.

Getting the nutrients you need

With good planning and an understanding of what makes up a healthy, balanced vegan diet, you can get all the nutrients your body needs.

If you don't plan your diet properly, you could miss out on essential nutrients. For example, vegans need to be careful to get enough calcium, iron and vitamin B12.

Vegans who are pregnant or breastfeeding

During pregnancy and when breastfeeding, women who follow a vegan diet need to make sure they get enough vitamins and minerals for their child to develop healthily. 

See vegetarian and vegan mums-to-be for more information.

If you're bringing up your baby or child on a vegan diet, you need to ensure they get a wide variety of foods to provide the energy and vitamins they need for growth.

See vegetarian and vegan babies and children for more information.

Getting enough calcium and vitamin D

Calcium is needed for strong and healthy bones and teeth. Non-vegans get most of their calcium from dairy foods (milk, cheese and yogurt), but vegans can get it from other foods.

Good sources of calcium for vegans include:

  • fortified soya, rice and oat drinks 
  • calcium-set tofu
  • sesame seeds and tahini
  • pulses
  • brown and white bread (in the UK calcium is added to white and brown flour by law)
  • dried fruit such as raisins, prunes, figs and dried apricots

The body needs vitamin D to absorb calcium. Vegan sources of vitamin D are:

  • exposure to summer sunshine - remember to cover up or protect your skin before it starts to turn red or burn (see sunlight and vitamin D)
  • fortified fat spreads, breakfast cereals and soya drinks (with vitamin D added)
  • vitamin D supplements

Read the label to ensure the vitamin D used in a product is not of animal origin.

Getting enough iron

Iron is essential for the production of red blood cells. A vegan diet can be high in iron, although iron from plant-based food is absorbed by the body less well than iron from meat.

Good sources of iron for vegans are:

  • pulses
  • wholemeal bread and flour
  • breakfast cereals fortified with iron
  • dark-green leafy vegetables such as watercress, broccoli and spring greens
  • nuts
  • dried fruits such as apricots, prunes and figs

Getting enough Vitamin B12

The body needs vitamin B12 to maintain healthy blood and a healthy nervous system. Vitamin B12 is only found naturally in foods from animal sources. Sources for vegans are therefore limited and a vitamin B12 supplement may be needed.

Sources of vitamin B12 for vegans include:

  • breakfast cereals fortified with B12
  • soya drinks fortified with vitamin B12
  • yeast extract such as Marmite

Vegan sources of omega-3 fatty acids

Omega-3 fatty acids, primarily those found in oily fish, can help maintain a healthy heart and reduce the risk of heart disease when eaten as part of a healthy diet.

Sources of omega-3 fatty acids suitable for vegans include: 

  • flaxseed (linseed) oil
  • rapeseed oil
  • soya oil and soya-based foods, such as tofu
  • walnuts 

Evidence suggests that plant sources of omega-3 fatty acids may not have the same benefits in reducing the risk of heart disease as those in oily fish.

However, if you follow a vegan diet you can still look after your heart by eating at least five portions of a variety of fruit and vegetables a day, by cutting down on food that is high in saturated fat and watching how much salt you eat.
