Vegetarian diet for children
A vegetarian diet works well for children — with a bit of awareness around protein, iron, B12 and vitamin D. We help the family make it work day to day.
In short
Can children thrive on a vegetarian diet?
Yes — a vegetarian diet can be safe and nutritious for children when it's well planned.
A vegan diet for children requires significantly more planning and closer follow-up.
The most important thing is covering energy, protein and critical nutrients.
Does this sound familiar?
This might sound like your situation
Iron, B12, vitamin D, iodine, zinc and omega-3 need planning when children eat vegetarian or vegan.
- Your child or teenager wants to eat vegetarian
- You're unsure about iron, protein and B12
- Dinners need to work for the whole family
- You want to avoid the diet becoming too narrow
- You want recipes that actually get eaten
SmartEating recommends
What makes the biggest difference?
For vegetarian children, planning around protein and iron keeps the diet both safe and varied.
Enough concentrated energy
Bulky plant foods can fill children up before they've eaten enough calories.
Varied protein sources
Rotate legumes, eggs, dairy or tofu across the week to cover amino acid needs.
Iron paired with vitamin C
Plant iron absorbs better alongside vitamin-C-rich fruit or vegetables.
B12 supplementation if vegan
B12 is not reliably available from plant foods alone and needs a supplement.
Year-round vitamin D
Norwegian sunlight is insufficient for most of the year, so supplements are needed.
When should you get follow-up?
A specialist should always be involved with vegan children.
- When transitioning to vegetarian/vegan
- Stalling growth
- Repeated infections
- Fatigue
- A breastfeeding mother on a strict plant-based diet
Blood tests with your GP should be done before and after switching.

The knowledge behind the advice
Children
The childhood years lay the foundation for eating habits, growth, and a relationship with food that often lasts a lifetime. Nutritional needs change rapidly through childhood, and the focus should be on varied, energy-dense, and safe food in a calm mealtime environment.
Legumes
Legumes such as beans, lentils and chickpeas are among the most nutrient-dense and sustainable foods available. They combine plant-based protein with abundant fibre, and are a valuable food group whether you eat a lot of meat or very little.
Vegetables
Vegetables are one of the most recommended food groups in any diet, known for their low energy content and high content of vitamins, minerals, fibre and plant compounds. A varied and generous intake of vegetables is one of the clearest recommendations in nutrition.
