During the last 18 years, considerable research has been conducted on the role of dietary fiber in health and disease. Interest was stimulated by epidemiologic studies that associated a low intake of dietary fiber with the incidence of colon cancer, heart disease, diabetes, and other diseases and disorders. Dietary fiber is not a single substance. There are significant differences in the physiological effects of the various components of dietary fiber. A Recommended Dietary Allowance for dietary fiber has not been established. However, an adequate amount of dietary fiber can be obtained by choosing several servings daily from a variety of fiber-rich foods such as whole-grain breads and cereals, fruits, vegetables, legumes, and nuts.
在过去的18年里，人们对膳食纤维在健康与疾病中的作用进行了大量研究。将膳食纤维低摄入量与结肠癌、心脏病、糖尿病及其他疾病和紊乱的发病率联系起来的流行病学研究激发了人们的兴趣。膳食纤维并非单一物质。膳食纤维的各种成分在生理效应上存在显著差异。目前尚未确定膳食纤维的推荐膳食摄入量。然而，通过每天从各种富含纤维的食物中选择几份来摄入足够量的膳食纤维是可行的，这些食物包括全麦面包和谷物、水果、蔬菜、豆类和坚果。
