Is a vegan diet suitable for children?

In this blog we take a look a planning meals and snacks for vegan children.

A number of food trends have become popular over the last few years, including a shift towards a vegan diet. According to Google searches, interest in the vegan diet has increased seven fold in the five years between 2014 and 2019. It now gets almost four times more interest than vegetarian and gluten free searches. The Vegan Society reports there are currently 600,000 vegans (1.16% of the population) in Great Britain. While it’s thought the number of vegan children is on the rise in the UK, current figures only accounts for people over the age of 15 years.

The Veganuary campaign, which encourages people to go vegan for the month of January, had 582,000 people sign up in 2021, in comparison to 400,000 people in 2020, and up from 59,500 in 2017! We are also seeing an increase in vegan food products as demand for meat-free food in the UK increases. In 2018, one in six products launched in the UK carried a vegan claim. Across 2019 this figure rose to nearly one in four. During 2020 every one of the top UK supermarkets (by revenue) had their own vegan range and every one of the top UK restaurants / food-to-go outlets has a vegan (or plant-based) offering.

 In the UK, vegan rights are protected under the human rights and quality law (Equality Act 2010).

So what does a vegan diet look like?

Vegans follow a plant-based diet which does not include meat, fish or other substances that come directly from killing an animal or from agricultural practices which lead to unnecessary death or suffering of any animal. You can follow a vegan diet by including a range of fruits, vegetables, nuts, grains, seeds, beans and pulses. Vegan diets will not include:

  • dairy products such as cows’ (or other animal) milk
  • milk products such as cheese and yoghurt
  • eggs or foods containing eggs
  • honey
  • any foods which contain gelatin or animal fats
  • products fortified with vitamins that have come from an animal source (for example, vitamin D which is added to some foods and drinks, and which usually comes from sheep wool lanolin).

What are the recommendations for vegan children?

The recommended age to introduce vegan and vegetarian babies to solid foods is around 6 months (the same advice for non vegan and vegetarian babies). You can find further information and advice on in our blogs on the introducing solid foods and feeding your toddlers.

The British Dietetic Association has stated that a well-planned vegan diet can “support healthy living in people of all ages”. The First Steps Nutrition Trust also state that “vegan diets can be safely given to infants and children providing that care is taken that all nutritional needs are met”.

Infants and young children, in particular, need enough energy (calories) to grow and be active, and enough nutrients (protein, fat, carbohydrate, vitamins and minerals) to ensure they remain healthy, fight infections, and support learning and levels of activity. It is possible for infants and children to get all the nutrition they need from a vegetable-based diet, but it does take thought and planning.

It’s essential that early years staff speak to parents and understand what families do and don’t eat. It’s also important for families to seek advice on diet and health from an appropriate health professional and receive guidance if using specialist vegan supplements, e.g. vitamin drops, to ensure the dosage is correct.

Eating well in the first 6 months

Breast milk meets all the nutritional needs of infants in the first 6 months of life. There are no infant formulas suitable for vegan infants currently for sale in the UK because, even if they contain no animal-derived ingredients (for example, if they are made from soya rather than cows’ milk), the vitamin D that is added to them is sourced from sheep’s wool.

The following should also be considered for other infant formulas:

  • Soya-based infant formula is suitable for vegetarian infants, but should not be given to infants under 6 months of age, and not used as the main milk drink for infants until they are over the age of 1, unless recommended by a health professional. Although these milks are available, there is no evidence that they prevent food allergies or intolerance. They are not recommended for infants who have cows’ milk intolerance, as these infants may be, or may become, allergic to soya protein. Soya-based formulas are more likely to cause dental decay, as they contain glucose rather than lactose. There are also some concerns about the high levels of phyto-oestrogens which can pose a risk to future reproductive health.
  • A rice-based infant formula is available in Europe but this is not currently approved for sale in the UK. Families who buy this formula should be advised that the instructions for making the powdered milk up safely are not in line with UK recommendations and they should seek advice from a health professional. Any milk alternative made from rice that is not a highly modified formula (e.g. rice drinks), must not be offered to children under 5 due to the arsenic content.
  • Unsweetened calcium-fortified soya milk alternative can be used in cooking for vegan children from 6 months, but should not be used as the main milk drink until after 1 year of age. Breast milk, or an appropriate first infant formula, should remain the main milk drink from 6-12 months. Unsweetened calcium fortified soya milks are widely available and are usually inexpensive.

Eating well for vegan infants from 6 months

First foods for babies around 6 months of age include a wide range of unprocessed foods including vegetables, potatoes, cereal foods (such as rice, oats, polenta, semolina, pearl barley), pulses (peas, beans and lentils), tofu, ground nuts (whole nuts should not be offered to under 5’s due to the risk of choking) and seeds, and fruits.

Child eating brocoli

Salt, sugar and artificial sweeteners should not be added to foods for infants. Naturally sweet fruits (such as apples or bananas) and vegetables (such as carrots, sweet potatoes or butternut squash) can be used to sweeten foods rather than adding sugar. If using commercial baby foods (such as jars and pouches), follow the manufacturer’s instructions carefully. Just be mindful that these foods are usually expensive, less nutritious, sweet, bland in taste and often very smooth compared to foods you can make yourself at home.

Important nutrients in vegan diets for 1-4 year olds

Offering children a variety of foods will help to ensure they get all the nutrients they need to grow and develop. Vegan children must be offered adequate amounts of foods that supply these nutrients, or be offered fortified foods and/or supplements. Vegetarian and vegan foods can be higher in fibre and lower in calories than a diet that includes meat. When it comes to starchy foods, in addition to wholegrain and wholemeal versions, children need some lower-fibre foods, such as white bread and rice, until they are 5 years old. This is because wholegrains are high in fibre and can fill children up before they have taken in enough calories and nutrients. The following are the key nutrients that need to be considered when following a vegan diet:


Iron is essential for the function of several body systems, particularly the pigmentation of red blood cells, called haemoglobin, which carry oxygen. A deficiency in iron can cause anaemia. This results in less oxygenated blood,  meaning the body receives less oxygen than it needs, which limits our ability to be physically active. Children with iron deficiency will often appear pale, tired and their general health, resistance to infection, appetite and vitality will be impaired. It is important to speak to a healthcare professional if you are concerned about your child’s iron levels. Suitable sources of iron for vegan children include:

  • fortified cereals (some may contain Vitamin D which may not be suitable for vegans based on how it is sourced)
  • dark-green leafy vegetables e.g. kale
  • wholegrains, such as wholemeal bread and brown rice (please note that children need a variety of while and wholemeal)
  • beans and lentils
  • smooth nut butters
  • tofu
  • quinoa
  • dried fruit, such as apricots and figs. Remember: offer these with meals, rather than as a snack between meals, to help prevent tooth decay.

Tip: The absorption of iron may be enhanced if foods or drinks rich in vitamin C are consumed at the same meal e.g. pepper, broccoli, cabbage, kiwifruit, pineapple.


Protein is needed for growth, maintaining and repairing body tissues, and to make the enzymes that control many body functions. Good sources of protein for children who eat some animal foods include:

  • dairy 
  • eggs 
  • fish

Vegan children can get enough protein as long as they eat a good variety of foods each day. Plant foods that contain protein include:

  • beans and lentils, and foods made from them – such as tofu, hummus and soya mince
  • soya milk alternative and yoghurt (unsweetened varieties)
  • seeds
  • finely ground nuts or smooth nut butters.

Please note: peanuts and allergies

If your child already has a diagnosed food allergy, or there is a history of allergies in your child’s immediate family – including asthma, eczema or hayfever – families should talk to their health visitor or GP before offering foods containing peanuts for the first time.


Requirements for calcium are high in children aged 1-4 years. Calcium is needed for building and maintaining good bone health, for the transmission of nerve impulses, muscle actions and for many other bodily functions. Whole milk and full-fat dairy products are a good source of calcium. Suitable alternatives to milk and dairy foods include:

  • unsweetened calcium-fortified milk alternatives, such as soya drinks, from the age of 1 as part of a balanced diet (rice milk is not suitable for children under 5 years)
  • green leafy vegetables – such as broccoli, cabbage and okra, but not spinach
  • soya beans
  • tofu
  • ground nuts and smooth nut butters
  • bread and anything made with fortified flour.

Rice Milk

Vitamin B12

Vitamin B12 interacts with folate and vitamin B6. Together, these vitamins help the body to build up its own protein. B12 is essential for the formation of red blood cells and a healthy nervous system. Vitamin B12 is found in animal foods including eggs, cheese and milk.

Children may show signs of a B12 deficiency more rapidly than adults. Deficiency may lead to loss of energy and appetite and failure to thrive and, if not corrected quickly, it can lead to permanent damage. Recommendations for the amount of vitamin B12 needed in fortified foods or as a supplement vary. As a sensible measure, The Vegan Society recommends that young children aged 1-4 years have about 1.5 micrograms a day from fortified foods and a supplement of 3 micrograms a day. There are no children’s vitamin supplements available which provide this amount. However, a children’s dose of the Vegan Society supplement VEG1 (half a tablet) would provide 12.5 micrograms a day, which is still a safe dose.

Foods that may be fortified with vitamin B12 include:

  • baby and breakfast cereals, soya yoghurts, and non-dairy milks such as soya, oat and almond (300-400ml of fortified unsweetened milk alternatives will provide adequate vitamin B12 (about 1.5 micrograms a day))
  • Vitamin B12 is also found in yeast extract, which is suitable for vegans – parents should choose a brand with no added salt if offering to their child.

Parents or guardians should consult a GP if they are worried that their child may have vitamin B12 deficiency.


Iodine is essential for the production of the hormone thyroxine, which affects the function of the thyroid gland. It is used to regulate the body’s metabolism, and affects the heart rate, body temperature and how the body uses energy from food. It is also important for brain development. Children aged 1-4 years need about 80 micrograms of iodine a day. Too much iodine can be harmful and parents or guardians should take advice before giving 1-4 year olds supplements or fortified foods that will provide more than 200 micrograms of iodine a day.

For many years iodine intake in the UK was thought to be more than adequate but recent research has shown mild iodine deficiency in schoolgirls and pregnant women. There is now concern that many adult women may not be getting enough iodine, particularly in pregnancy.

Iodine is found in a range of foods, the richest sources being fish and dairy products. Seaweed is a concentrated source of iodine, but it can provide excessive amounts (particularly so in the case of brown seaweed such as kelp) and therefore eating seaweed more than once a week is not recommended, especially during pregnancy. White fish contains more iodine than oily fish. Milk and dairy products are the main sources of iodine for most people.

Research in the UK has shown that organic milk has a 35-40% lower iodine content than conventional milk. Soya milk is rarely fortified with iodine (check the label) and therefore will not replace the iodine in cows’ milk. Vegetarians and particularly vegans are at risk of iodine deficiency as they do not eat rich iodine sources (fish and/or dairy products).

Plant-based sources of iodine suitable for vegans include:

  • cereals and grains, such as whole wheat and rye. However, the levels of iodine in these foods vary widely and relying on these alone will not provide sufficient iodine.

It is recommended that all 1-4 year olds take an iodine supplement rather than use sea vegetables as a source of iodine.


Omega-3 fats have been recommended in the diet to prevent heart disease in adults. Omega-3 fatty acids are mainly found in oily fish, such as salmon and mackerel. Other sources of omega-3 include:

  • flaxseed (linseed) oil
  • rapeseed oil
  • soya oil and soya-based foods, such as tofu
  • walnuts – offer these ground or as a nut butter for children under 5 to reduce the risk of choking
  • eggs enriched with omega-3 (for non vegan children).

Omega-3 fats are found in both animal and vegetable foods, but vegetable sources of omega-3 fats do not provide the same fatty acids as those from animal (fish) sources.

Although alpha-linolenic acid (ALA) is present in vegetable oils and seeds such as rapeseed, soy, flaxseed, hemp, chia and walnuts for example, ALA is poorly converted into DHA and EPA – the fatty acids that are associated with better heart health and that are found in fish oils. Any health consequence of lower amounts of DHA and EPA in vegans is poorly understood, but eating a good mixed diet, including good sources of ALA, is recommended. Micro-algal sources of omega-3 fats have been suggested for vegans, but the impact of these on health is not yet known.

Vitamin Supplements for children

The Department of Health recommends that all children aged 6 months* to 5 years are given vitamin supplements containing vitamins A, C and D every day. It’s also recommended that babies who are being breastfed are given a daily vitamin D supplement from birth, whether or not mums are taking a supplement containing vitamin D.  Vitamin D2 is suitable for babies and children who have a vegan diet, and you can also get supplements containing vitamin D3 derived from lichen. It is important to speak to your health visitor for advice on vitamin drops for babies and young children. 

*Babies who are having more than 500ml (about a pint) of infant formula a day don’t need vitamin supplements because formula is fortified with vitamins.

Vitamin supplements for breastfed infants

It is recommended that all breastfed babies have a supplement of 8.5-10 micrograms of vitamin D a day from birth (or in some areas, from 1 month).

Healthy Start vitamin drops will be suitable for use from birth from 2018/2019, but vegan families may not want to use these for their infants as they include vitamin D sourced from sheep’s wool lanolin.

Baby DDrops contain 10 micrograms of vitamin D and the manufacturer suggests that the drops can be put directly on the breast when breastfeeding. However, parents are advised to put the drops on a sterilised spoon to give to their infant as this can be a safer way of getting the right dose. The manufacturers say the vitamin D is sourced from sheep’s wool lanolin, but that animals are not harmed in the process.

A number of other supplements are marketed as suitable for vegan infants – for example, Abidec and BioCare Baby A, C, D Plus drops. These supplements contain a range of other nutrients as well as vitamin D, but BioCare Baby dose not provide the new recommended dose of 8.5-10 micrograms of vitamin D. If there is any concern about vitamin D intakes specifically, then vegan vitamin D supplements are available and families should talk to their pharmacist or GP.

Vitamin supplements for 1-4 year olds

Abidec vitamin drops are suitable for vegan children, and for vegan 1-4 year olds 0.6ml a day is recommended. This provides about 700 micrograms of vitamin A, 10 micrograms of vitamin D,
0.4mg thiamin, 0.8mg riboflavin, 0.8mg vitamin B6, 8mg niacin and 40mg vitamin C. Families may prefer to give vitamin D separately in the form of Vitashine spray (available from
pharmacies) which provides 25 micrograms of vitamin D a day and is within safe limits for children aged 1-4 years, providing the dose is not exceeded. Families who wish to provide additional vitamin B12 and iodine should ask their pharmacist or another health professional for advice about a suitable supplement for a 1-4 year old vegan child

Information about suitable supplements can also be found on The Vegan Society website. Families are strongly advised to seek advice from a health professional to ensure they do not provide harmful doses of any nutrients to infants.

Challenges for vegan children

If families choose to follow a vegan diet it’s important they understand that growing children need plenty of energy (calories) and nutrients (protein, fat, carbohydrate, vitamins and minerals) to ensure they grow and develop well. Vegan diets are based on vegetable foods only, so extra care must be taken to make sure that vegan children get a good variety of foods that can provide all the nutrients they need. Planning is key and parents therefore need to be very well informed to ensure they reduce the risk of vitamin D, calcium, iron and possibly vitamin B12 deficiency. In the toddlers years, fussy eating can be common and children typically have small appetites, so achieving their daily calorie needs can be a challenge. It is important for families to liaise with a health professional if choosing a vegan diet for their child and refer to the resources listed below for practical support.

Choosing vegan products

If following a vegans diet many families are very confident on planning meals to meet their nutrient requirements and so will be very familiar with the fruit and vegetable aisle! Other staples like grains, nuts, beans and pulses will likely take up much of the shopping trolley and unprocessed foods like these are often the easiest to determine as vegan. There is however an increasing rise in the number of processed vegan products on the market. Between 2012 and 2016 there was a 185% increase in the number of vegan products launched in the UK! Just Eat reported that demand for vegetarian options among its customers grew by 987% in 2017. Veganuary often see the launch of new vegan menus such as Greggs Vegan Sausage roll and Domino’s Vegan Pepperphoni pizza!! It is always important to read the labels when making food choices. While vegan ‘meats’ are often perceived to be healthier they can contain on average even more salt than meat burgers. Any food that has been highly processed should be eaten occasionally, so not necessarily avoided completely, but some vegan products may have a high salt content with added additives and preservatives. Also consider the overall nutritional value of the product you are buying.
