Experts Warn About the 'Fibermaxxing' Trend for Gut and Mental Health

A TikTok trend called 'fibermaxxing' involves eating high-fiber foods to improve gut health and overall wellness. Experts agree that increasing fiber intake is beneficial, especially given the low average consumption in the US, and can help prevent chronic diseases like colon cancer, diabetes, and heart disease. However, gradual changes are recommended to avoid digestive discomfort, and a balanced intake of soluble and insoluble fiber from whole foods is best. Supplements can help if needed, but should not replace whole foods.
