Key facts

- Supports gut health and steady blood sugar.
- Aim for roughly 25–38 g per day.
Fiber passes through your digestive system largely intact, which is exactly why it's useful. Soluble fiber slows digestion and helps steady blood sugar and cholesterol; insoluble fiber adds bulk and keeps things moving. Together they support a healthy gut and regular digestion.
For anyone managing their weight, fiber's biggest practical benefit is satiety: high-fiber foods like vegetables, fruit, oats, and legumes are filling for few calories, making a calorie deficit easier to maintain. Most people fall short of the recommended 25–38 grams a day.
