Common mistakes around Ballaststoffe Senioren

A common mistake among seniors is abruptly increasing fiber intake without adjusting fluid consumption. Fiber binds water; without adequate hydration, this can lead to constipation or even intestinal obstruction. Additionally, the aging gut microbiome is less adaptable – rapid increases cause bloating and discomfort. Many seniors avoid fiber due to fear of digestive issues, yet soluble fibers (oats, psyllium) reduce fall risk by improving blood sugar and cholesterol control. Another mistake: relying solely on wheat bran, which is high in insoluble fiber but low in prebiotics. A mix of soluble (fruits, vegetables, legumes) and insoluble fibers (whole grains) is recommended, gradually increased to 25–30 g/day. Fiber can also interfere with medication absorption – it should be taken at a different time from pills. Evidence is based on dietary guidelines and observational studies, not large RCTs in the elderly. Caveat: individual tolerance and kidney function must be considered.
