Hello, is there a formula for the amount of fiber that a women and men needs daily?

The general recommendations for fiber for those age 50 or younger are:

• 25 grams/day for women
• 38 grams/day for men

For those age 51 or older:

• 21 grams/day for women
• 30 grams/day for men

The average intake of fiber in the U.S. is well below these recommendations at 14 g/day.
