Is A Vegan Diet Safe For Kids? How To Raise Children On Plant-Based Food

Is a vegan diet safe for kids? Here's what you need to know about how to raise children on plant-based foods


7 Minutes Read

Good nutrition from a variety of foods is especially important during childhood as it’s a time of rapid growth and development.  But is a vegan diet safe for kids?

Experts agree that a well-planned, varied vegan (aka plant-based) diet is suitable for everyone, including children. 

A plant-based diet contains all the healthy fats, protein, carbohydrates, vitamins, and minerals growing bodies need. It also avoids saturated animal fat, animal protein, hormones, and other undesirable substances linked to health issues and disease.

Soy-based infant formula

To make sure your vegan child is getting the best nutrition to thrive, you need to start with the basics. 

Infants under six months only need breastmilk; for those who can’t breastfeed, soy-based infant formulas offer a safe alternative. 

In the US, millions of babies have been fed soy formula over the last 40 years with no adverse effects. However, official guidelines recommend you speak to your GP before using it. And never try to make your own formula at home. Baby formula contains a specific balance of nutrients key for your child’s health.

Vitamin D

The government recommends daily vitamin D drops for breastfeeding babies. Vitamin D2 is suitable for vegans while D3 usually comes from sheep’s wool; but you can get vegan D3 supplements made from lichen

Babies fed formula milk should not be given extra vitamin D if they’re having more than 500 millilitres (about a pint) a day because milk already contains it.

Solids foods at six months

You can start your baby on solid foods at six months, but don’t expect them to eat much! It’s really about getting them used to different flavours and textures – they’ll be getting most of their energy and nutrients from milk.

Good foods to start with include mashed avocado, sweet potato, banana, and porridge with soya milk. Home-made fruit purées add vitamins while mashed lentils, chickpeas, or tofu provide iron. 

When they start teething, introduce “finger foods” such as soft-cooked vegetables, strips of bread, or chunks of apple and pear. Avoid giving children under five whole nuts and make sure you always watch your baby eating as there’s a risk of choking, whatever the diet.

12 months

From 12 months they may be eating three meals a day plus snacks to supply them with lots of energy, protein, and iron. Include protein-rich beans, chickpeas, lentils, nut and seed butter, calcium-fortified yogurt, and drinks. 

Experiment with fruit and vegetables, aiming for at least five child-sized portions a day. Mix white and wholegrain pasta, couscous, bread and rice to avoid filling up their small stomachs with too much fiber. Increase the amount and variety of foods until they are eating the same as you, but in smaller portions. 

Vegans need a reliable source of vitamin B12, so when they begin eating solid foods so make sure to include B12-fortified drinks, yogurts, and nutritional yeast, or a children’s B12 supplement.

Foods to avoid

Avoid low-fat foods – children need lots of energy! It’s also recommended to avoid foods with added sugar and salt. Too much sugar causes tooth decay, and a taste for salty food can contribute to high blood pressure in later life. 

Avoid too many unhealthy junk foods and snacks; lead by example and eat the same foods as they do. For older children and teenagers, the main food groups remain the same – fruit and vegetables, whole grains, pulses, nuts, and seeds.


All plant foods contain protein and if children are getting enough calories in a varied vegan diet, they will be getting enough protein. Just make sure you include plenty of whole-grain foods (for older children), pulses, and nut and seed butters.

Iron deficiency is common among small children so be sure to include plenty of beans, chickpeas, lentils, tofu, nut butters, and dried figs in your child’s diet. 

Vitamin C helps iron absorption so combine these iron-rich foods with peppers, broccoli, mango, citrus fruit, and strawberries. Baked beans on wholemeal toast with orange juice ticks the right boxes.


Almost one in five girls in the UK falls short on calcium, important for healthy teeth and bones. Good sources include calcium-set tofu, fortified vegan breakfast cereals and plant milks, figs, kale, sesame seeds and tahini (sesame seed paste), wholemeal bread, baked beans, butternut squash, almonds and Brazil nuts, spring greens, and watercress. 

Tahini is a calcium powerhouse with one teaspoonful providing around a third of the daily calcium needs of one to five year-olds. Make hummus with tahini for your child to dip veggie sticks in.

We make vitamin D in our skin when it’s exposed to sunlight. It helps with calcium absorption. Your child could be getting all the calcium they need but without vitamin D, they may not absorb it sufficiently. From six months to five years, the government says that all children – regardless of diet – should be given a daily supplement containing vitamins A, C, and D.

Iodine, omega-3s, and zinc

Seaweed is a great source of iodine. And nori, used for sushi or sprinkled on meals a couple of times a week, is a good way to ensure a regular intake. Avoid giving your child kelp (kombu) as it contains excessively high amounts. Some plant milks also now contain iodine.

Children need essential omega-3 fats in their diet for healthy brain and eye development and function. The best sources are ground flaxseed and rapeseed and their oils, ground chia seeds, ground hemp seeds, and walnuts (ground if under five), stirred into smoothies and cereal. Ground seeds are better as whole seeds can just pass straight through you!

Zinc is important for a healthy immune system and the growth and repair of body tissues. Government surveys show that almost a quarter of teenage girls are falling short, with teenage boys not far behind. Good sources include tempeh (fermented soya beans), wholewheat spaghetti, tofu, quinoa, pumpkin seeds, lentils, couscous, brown rice, cashew nuts, sesame seeds, and tahini.

The best start

Concern about the adequacy of a vegan diet obscures the fact that children in the UK (and beyond) are generally not doing very well nutrition-wise. Almost a third of those aged 2-15 are overweight or obese and this can have a significant impact on both physical and mental health.

Overweight and obese children are likely to stay obese into adulthood and more likely to develop diabetes and cardiovascular diseases at a younger age. A plant-based diet can lower the risk of all these threats.

Following this guidance will help give your child the best start as healthy eating patterns are established early in life – so well done vegan parents, we salute you!
