Vegetarische und vegane Ernährung bei Kindern und Jugendlichen – ein Update
摘要
Vegetarian and vegan dietary patterns are becoming increasingly more popular, particularly among young adults and adolescents. Accordingly, pediatricians see more families who wish to feed their children on a vegetarian or vegan diet as well as those who reduce their intake of specific food groups, such as dairy or meat products or use plant-based alternatives without necessarily adhering to a specific dietary pattern.
In principle, the exclusion of certain foods in any dietary approach can result in a critically low nutrient intake. Recent systematic reviews have shown that avoiding animal products is associated on the one hand with better cardiovascular health and lower body fat. On the other hand, intake of nutrients such as iron, omega‑3 fatty acids (DHA) and especially vitamin B12 are often critically low. Furthermore, other nutrients such as iodine, calcium, vitamin D, and protein have come into focus as inadequate intake can negatively affect growth and bone health. When avoiding animal products, comprehensive knowledge and discipline are required to optimally select plant-based foods and to consistently adhere to necessary supplementation, as with vitamin B12. This is particularly important for maternal nutrition during pregnancy and lactation.
The final part of the statement provides practical recommendations for complex medical management. As part of empathic and individualized care, a detailed dietary assessment, personalized nutrition counselling with supplementation guidance and monitoring of the nutritional status are necessary; if required, complemented by laboratory diagnostics.
