Can vegetarian or vegan protein be enough for children and teens?
Yes, vegetarian and vegan diets can provide enough protein for children and teenagers when they are well planned. Protein supports growth, muscle development, hormones and healthy tissues, so it is important during childhood and the teenage years.
The main point is variety. Children do not need every meal to be protein-rich, but they do need regular sources across the day from foods such as beans, lentils, tofu, soya yoghurt, nuts, seeds and wholegrains.
How much protein do young people need?
Protein needs vary by age, size and how active a child is. In the UK, most children and teens who eat enough food overall will get sufficient protein, even on a plant-based diet.
Growing children may need a little more protein per kilogram of body weight than adults. That makes it sensible to include a protein food at each meal and snack, especially for teenagers who are growing quickly or playing sport.
Best plant-based protein foods
Good vegetarian protein sources include eggs, milk, yoghurt and cheese, as well as beans, chickpeas, lentils, peas and soya foods. For vegan diets, soya products are especially useful because they are high in protein and versatile.
Other helpful foods include nut butters, seeds, tofu, tempeh, edamame, quinoa and fortified plant yoghurts. Wholemeal bread, oats and pasta also add to daily protein intake when eaten as part of a balanced diet.
What to watch for on vegan diets
Protein is only one part of the picture. Children and teens on vegan diets also need enough energy, iron, calcium, vitamin B12, iodine and vitamin D to support healthy growth.
Vitamin B12 is particularly important because it is not found naturally in plant foods. Vegan children and teenagers need reliable B12-fortified foods or a supplement, ideally with advice from a GP or dietitian.
Practical tips for parents and carers
Try to build meals around familiar foods. For example, bean chilli with rice, lentil pasta bolognese, tofu stir-fry, peanut butter on wholemeal toast or hummus in sandwiches can all boost protein intake.
Snacks can help too, especially for teens with bigger appetites. Ideas include soya yoghurt, roasted chickpeas, nuts and seeds if age-appropriate, or a smoothie made with fortified plant milk and nut butter.
When to get advice
If you are worried about a child’s growth, appetite or weight, speak to a GP, health visitor or registered dietitian. This is especially important for babies, children with medical conditions, picky eaters or families new to vegan eating.
With the right planning, vegetarian and vegan diets can support healthy growth and development. The key is to offer enough food, enough variety and the right nutrients over time.
