Lay opinion vs evidence: Ballaststoffe Kinder

Dietary fiber for children is often surrounded by exaggerated lay opinions. Evidence shows that adequate fiber intake (from whole grains, fruits, vegetables) supports digestion, prevents constipation, and may reduce long-term obesity risk. However, there is no strong proof that specific fiber sources or supplements provide 'detox' or 'immune-boosting' effects in children. Recommended intake is about 10 g plus 1 g per year of age (up to 25 g). Excessive fiber can cause bloating or abdominal discomfort. A balanced diet with natural fiber is preferable to isolated products. Overall evidence is moderate, not strong.
