Fiber is the part of plant food that the body barely digests, and that’s exactly why it matters so much: it keeps digestion moving, helps steady blood sugar, and keeps you feeling full for longer. Fiber is also one of those nutrients that most people consistently fall short on.

How much fiber adults actually need

The commonly cited target in most nutrition guidelines is around 25-30 g of fiber a day for an adult. More detailed guidelines sometimes split the number by sex: roughly 25 g a day for women and 35-38 g for men, largely because men tend to eat more calories on average — fiber recommendations are often tied to total calorie intake, with a rough rule of about 14 g of fiber per 1,000 calories consumed.
