Dietary fiber is crucial for seniors: it supports regular bowel movements, prevents constipation, stabilizes blood glucose, and soluble fiber (e.g., from oats, legumes) lowers LDL cholesterol, reducing cardiovascular risk. The German Nutrition Society recommends at least 30 g fiber daily for adults over 65, yet many consume only 15–20 g. A gradual increase over several weeks and adequate fluid intake (1.5–2 L/day) are essential to avoid bloating or discomfort. For chewing or swallowing difficulties, soaked psyllium husks, ground flaxseeds, or fiber powders (e.g., acacia fiber) can be used. Important: fiber may interfere with medication absorption (e.g., thyroid hormones, anticoagulants) – take them at least 2 hours apart. A MyBody-X microbiome test can offer insights into gut flora but does not replace medical advice. The evidence for fiber benefits is strong (human-strong), but effects vary individually. No blanket recommendations without considering conditions like diverticulitis or kidney disease.
