Lay opinion vs evidence: Ballaststoffe Frauen

Lay opinions about dietary fiber for women often range from 'more is always better' to 'fiber is unnecessary'. The scientific evidence, however, is robust: fiber is crucial for women's health. It supports digestive health, reduces the risk of cardiovascular disease, type 2 diabetes, and certain cancers (e.g., colorectal cancer), and aids in weight management. The German Nutrition Society recommends about 30 g per day for women, yet average intake is much lower. A gradual increase and adequate hydration are important to avoid bloating or constipation. The provided context does not contain specific fiber studies; it focuses on DNA tests with often weak evidence. Therefore, this answer relies on well-established dietary guidelines and epidemiological data. The evidence for fiber is strong (human-strong), but individual genetic variants play a minor role. Women should not be misled by DNA tests claiming to personalize fiber needs; instead, they should focus on a varied, fiber-rich diet including whole grains, legumes, nuts, fruits, and vegetables.
