Arch Pediatr. 2019 Oct;26(7):442-450. doi: 10.1016/j.arcped.2019.09.001. Epub 2019 Oct 12.


The current craze for vegan diets has an effect on the pediatric population. This type of diet, which does not provide all the micronutrient requirements, exposes children to nutritional deficiencies. These can have serious consequences, especially when this diet is introduced at an early age, a period of significant growth and neurological development. Even if deficiencies have less impact on older children and adolescents, they are not uncommon and consequently should also be prevented. Regular dietary monitoring is essential, vitamin B12 and vitamin D supplementation is always necessary, while iron, calcium, docosahexaenoic acid, and zinc should be supplemented on a case-by-case basis.
