Dietary fiber is especially important for seniors to maintain digestive health, prevent constipation, and reduce the risk of cardiovascular disease, type 2 diabetes, and certain cancers. However, seniors should ensure adequate fluid intake when increasing fiber, as fiber binds water and can otherwise cause discomfort. A gradual increase is recommended to avoid bloating and gas. Good sources include whole grains, legumes, nuts, seeds, fruits, and vegetables. For those with conditions like diverticulitis or irritable bowel syndrome, fiber intake should be individualized. The general recommendation is about 30 g per day, but many seniors consume far less. A stepwise increase combined with sufficient fluids is key. The evidence for these recommendations is strong (human-strong), based on epidemiological studies and clinical guidelines.
