Fiber is incredibly important.

It leaves your stomach undigested and ends up in your colon, where it feeds friendly gut bacteria, leading to various health benefits (1, 2).

Certain types of fiber may also promote weight loss, lower blood sugar levels and fight constipation (3, 4, 5).

The recommended daily intake is 25 grams for women and 38 grams for men (6).

However, most people are only eating around half of that, or 15–17 grams of fiber per day (7).

Fortunately, increasing your fiber intake is relatively easy — simply integrate foods into your diet that have a high percentage (%) of fiber per weight.

Here are 22 high-fiber foods that are both healthy and satisfying.
