It is likely that we evolved on a high-fiber diet because of the unavailability of processing techniques. Some have estimated that our fiber consumption may have been as high as 50 grams daily when fiber-rich foods were more bountiful in our diet. Some current populations in Africa have been noted to retain high-fiber intakes. On the other hand, it is estimated the average American woman and man eats about 12 grams and 18 grams of dietary fiber daily, respectively.
The Adequate Intake (AI) recommendation for total fiber intake for adults who are 50 years of age and younger is 38 grams per day for men and 25 grams for women daily. For adults over 50 years of age, the recommendation is 30 grams per day for men and 21 grams for women. Or 14 grams per 1,000 calories consumed. Table 4.7 provides an overview of fibers commonly used in nutrition supplements and as a food additive.
