The fiber gap: why most women fall short, and why it matters

Health authorities recommend around 25 grams of fiber a day for women. Most get closer to half that. Nutrition researchers call it the fiber gap, and it's one of the most consistent shortfalls in the modern diet.

Why the gap exists

Fiber lives in the foods that modern eating patterns squeeze out: legumes, whole grains, vegetables, fruit with the skin on. Processed convenience foods are engineered for taste and shelf life, and fiber is usually the first casualty. You can eat a full day's calories and barely touch a third of your fiber target without noticing.

What the shortfall touches

• Your gut — fiber is the primary food source for your gut bacteria and the main driver of regularity.
• Your blood sugar — soluble fiber slows how fast glucose from a meal hits your bloodstream, smoothing the spike-and-crash cycle.
• Your fullness signals — fiber stretches and slows the stomach, which is a big part of why high-fiber meals keep you satisfied longer.
• Your hormones — the gut is a key exit route for metabolized estrogen, and fiber is part of what keeps that route moving.
