Introduction

The position of the German Nutrition Society on vegan diets was published in 2016 [1]. The conclusion of this position was that without supplementation of potentially critical nutrients, it is difficult or impossible to ensure an adequate supply of certain nutrients with a vegan diet. Therefore, those who wish to follow a vegan diet should take care to ensure they are adequately supplied with these (potentially) critical nutrients, especially vitamin B12. This can be achieved through the careful selection of foods with high nutrient density and by selecting foods that are enriched with the required nutrients and/or by taking nutritional supplements, as well as by having regular medical check-ups and consulting a qualified nutrition specialist (see Richter et al. 2016 [1]).

In population groups with special nutritional requirements, the risk of malnutrition or nutrient deficiency when following a vegan diet is higher than for healthy adults who follow this diet. These population groups include children from infancy onwards throughout the entire growth phase, adolescents, pregnant and lactating women [2]. At the time the position was published, there was a lack of up-to-date, conclusive studies on the basis of which the supply situation for these at-risk groups could be assessed. Therefore, the German Nutrition Society did not recommend a vegan diet during pregnancy or while lactating, or during childhood or adolescence. For those who nevertheless decide to adhere to a vegan diet or feed their children a vegan diet, advice has been issued on how to prevent nutrient deficiencies (see [1]).

Because several new publications on this topic have become available since the German Nutrition Society position on vegan diets was published, a systematic literature search update was performed with regard to the aforementioned at-risk groups.
