Observational studies have shown that dietary fiber intake is associated with decreased risk of cardiovascular disease. Dietary fiber is a non-digestible form of carbohydrates, due to the lack of the digestive enzyme in humans required to digest fiber. Dietary fibers and lignin are intrinsic to plants and are classified according to their water solubility properties as either soluble or insoluble fibers. Water-soluble fibers include pectin, gums, mucilage, fructans, and some resistant starches. They are present in some fruits, vegetables, oats, and barley. Soluble fibers have been shown to lower blood cholesterol by several mechanisms. On the other hand, water-insoluble fibers mainly include lignin, cellulose, and hemicellulose; whole-grain foods, bran, nuts, and seeds are rich in these fibers. Water-insoluble fibers have rapid gastric emptying, and as such may decrease the intestinal transit time and increase fecal bulk, thus promoting digestive regularity. In addition to dietary fiber, isolated and extracted fibers are known as functional fiber and have been shown to induce beneficial health effects when added to food during processing. The recommended daily allowances (RDAs) for total fiber intake for men and women aged 19–50 are 38 gram/day and 25 gram/day, respectively. It is worth noting that the RDA recommendations are for healthy people and do not apply to individuals with some chronic diseases. Studies have shown that most Americans do not consume the recommended intake of fiber. This review will summarize the current knowledge regarding dietary fiber, sources of food containing fiber, atherosclerosis, and heart disease risk reduction.

Abstract High fiber intake is associated with reduced mortality risk in both general and chronic kidney disease populations. However, in dialysis patients such data is limited. Therefore, the association between dietary fiber intake (DFI) and the risk of all-cause and cardiovascular disease (CVD) mortality was examined in this study. A total of 1044 maintenance hemodialysis (MHD) patients from eight outpatient dialysis centers in China were included in this study. Data on DFI was collected using 24-h dietary recalls for three days in a week and was normalized to actual dry weight. The study outcomes included all-cause and CVD mortality. Over a median of 46 months of follow-up, 354 deaths were recorded, of which 210 (59%) were due to CVD. On assessing DFI as tertiles, the CVD mortality risk was significantly lower in patients in tertile 2-3 (≥0.13g/kg/d; hazard ratio [HR]: 0.71; 95% confidence interval [CI]: 0.51-0.97) compared to those in tertile 1 (<0.13g/kg/d). A similar, but non-significant trend was found for the association between DFI (tertile 2-3 vs. tertile 1; HR: 0.83; 95%CI: 0.64-1.07) and all-cause mortality. In summary, higher DFI was associated with lower CVD mortality risk among Chinese patients of MHD. This study emphasized the significance of dietary fiber intake in MHD patients, and provided information that is critical for the improvement of dietary guidelines for dialysis patients.

Abstract The aim of this article is to review the definitions and regulations for dietary fiber and whole grains worldwide and to discuss barriers to meeting recommended intake levels. Plant foods, such as whole grains, that are rich in dietary fiber are universally recommended in dietary guidance. Foods rich in dietary fiber are recommended for all, but dietary recommendations for whole grains and dietary fiber depend on definitions and regulations. Official recommendations for dietary fiber in the United States and Canada are denoted by dietary reference intakes (DRIs), which are developed by the Institute of Medicine. An adequate intake (AI) for dietary fiber was based on prospective cohort studies of dietary fiber intake and cardiovascular disease risk that found 14 grams of dietary fiber per 1000 kilocalories protected against cardiovascular disease (CVD). This value was used to set AIs for dietary fiber across the life cycle based on recommended calorie intakes. Actual intakes of dietary fiber are generally about half of the recommended levels. Recommendations for whole grain intake are equally challenging, as definitions for whole grain foods are needed to set recommendations. The 2005 Dietary Guidelines for Americans recommended that half of all grain servings be whole grains, but usual intakes are generally less than 1 serving per day, rather than the recommended 3 servings per day. Scientific support for whole grain recommendations is based on the same prospective cohort studies and links to CVD protection used to inform dietary fiber guidance. Thus, dietary fiber is a recommended nutrient and whole grains are a recommended dietary pattern in dietary guidance in North America and around the world. Challenges for attaining recommended intakes of dietary fiber and whole grains include low-carbohydrate diets, low-gluten diets, and public health recommendations to avoid processed foods.
