What is the recommended daily fiber intake for adult women and men aged 19–50?

• A. About 25 g/day for women and 38 g/day for men (ages 19–50).
• B. About 20 g/day for women and 25 g/day for men.
• C. About 30 g/day for women and 45 g/day for men.
• D. About 15 g/day for both genders.

Answer: (A)

Fiber needs are given as daily grams and differ by sex because men generally have higher energy needs. For adults aged 19–50, the recommended daily fiber intake is about 25 grams for women and 38 grams for men. This level supports digestive health, can help lower cholesterol, and aids in blood sugar regulation when part of a balanced diet. To reach these targets, eat a variety of fiber-rich foods such as vegetables, fruits, whole grains, legumes, nuts, and seeds, and increase intake gradually with plenty of fluids to avoid gas or discomfort. The other options are simply below the established targets (or ignore the higher requirement for men) and don’t align with these guidelines.
