According to the Academy of Nutrition and Dietetics (USA), the recommended daily amount of fiber for women is 25 grams and, for men, it is 38 grams. After the age of 50, the recommended intake for women is 21 grams and men is 30 grams.
As most high fiber containing foods usually have insoluble and soluble fiber, it is not necessary to be too careful about dividing them up.
In other words, the focus should be on fiber intake in general, rather than on the specific type of fiber.
Consuming 25 grams of fiber each day should be enough to meet daily requirements. Ideally, individuals should consume at least five servings of fruit and vegetables, as well as some servings of whole grain products, each day.
