Currently, it is not possible to recommend a specific intake of fiber more research is needed. However, dramatic increases in dietary fiber should be avoided since the absorption of minerals may be reduced by high dietary fiber intakes. Moderate increases in the consumption of fiber can be easily achieved by increasing the consumption of nuts, vegetables, fruits, and whole grain cereal products. The fiber content of various foods is given in Food Composition Table F-21.

Nuts are a good source of dietary fiber. After cereals, nuts are the plant food highest in fiber, followed by legumes, whole grain bread, fruits, and vegetables [27]. Yet, this positive attribute of nuts is not well-known or publicized despite the fact that most populations globally do not consume the WHO recommended level of 25 g of fiber/d [28]. A standard serving of tree nuts provides 5%-10% of daily fiber requirements [24].
