Fiber 101: Why Most of Us Don't Get Enough (and What to Do About It)

Fiber doesn't have the glamour of protein or the buzz of the latest superfood, but it's one of the most consistent gaps in the American diet. General guidelines suggest around 25 grams per day for women and 38 for men — and most adults land closer to 15.

That gap matters because fiber does quiet, essential work: it supports digestive regularity, contributes to feelings of fullness, and is a cornerstone of heart-conscious eating patterns. Diets higher in fiber are consistently associated with better long-term health outcomes in population research.

The best sources are unglamorous: beans, lentils, oats, whole grains, apples, berries, and vegetables. The problem is that modern convenience food strips fiber out. White bread instead of whole grain, juice instead of fruit, refined snacks instead of nuts — the fiber disappears without anyone noticing.

Two kinds of fiber matter. Soluble fiber (oats, beans, apples) dissolves in water and forms a gel that supports fullness and heart-healthy eating. Insoluble fiber (whole grains, vegetable skins) adds bulk and supports regularity. You need both.

Start with food: swap in whole grains, add a piece of fruit, throw beans into a soup. Then, if your day still falls short — and for many busy people it will — a fiber supplement like FibRestore can bridge the difference with a mix of soluble and insoluble fiber.

One practical tip: increase fiber gradually and drink more water alongside it. Your digestive system appreciates a gentle ramp-up.
