Fibermaxxing: Why Increasing Fiber Intake Could Improve Long-Term Health

A growing trend known as “fibermaxxing” is drawing attention to the importance of dietary fiber for long-term health. Fiber supports digestion and has been associated with a reduced risk of several diseases, including certain cancers. The idea behind fibermaxxing is simple: consume at least the recommended amount of fiber daily based on body needs.

According to researcher Jennifer Lee at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, more people are focusing on “healthspan”—the number of years lived in good health—rather than just lifespan. Studies show that low fiber intake can contribute to metabolic and cardiovascular issues such as obesity and diabetes.

Health guidelines recommend about 22–34 grams of fiber daily, depending on age and sex. Fiber is found in two forms: soluble fiber, which helps regulate blood sugar and cholesterol, and insoluble fiber, which supports regular digestion and prevents constipation.
