A Review of the Associations between Dietary Fiber Intake and Cancer Prevention or Prognosis

Abstract

The increase in tumor incidence is closely related to dietary factors. In recent years, many researchers have carried out in-depth research to investigate whether increasing the intake of dietary fiber can prevent tumors and improve the prognosis, but the results have been unclear. We herein searched the literature in common academic databases and incorporated and summarized the relevant articles. The literature clearly indicates that dietary fiber can protect against the following cancers: colorectal cancer, breast cancer, pancreatic cancer, ovarian cancer, and head and neck cancer. There is also evidence that dietary fiber intake can exert protective effects against cancers of the liver, lung, stomach, small bowel, kidney, and esophagus, as well as lymphoma, but the data have so far been relatively limited. The effects on endometrial cancer and prostate cancer still remain uncertain. In terms of the effects on the cancer prognosis, dietary fiber does not appear to have an impact on colorectal cancer or breast cancer. Although more research is needed for some kinds of cancer, it is clear that increasing the intake of dietary fiber is beneficial for preventing the occurrence and development of several major types of cancer, with no major adverse effects. We therefore recommend that most of individuals increase their intake of dietary fiber.

Impact of Insoluble Dietary Fiber and CaCl2 on Structural Properties of Soybean Protein Isolate–Wheat Gluten Composite Gel

“…SIDF also has excellent water-and oil-holding properties, in vitro antioxidant activity, and low price, which improves its edible value. Moreover, it has been implicated in reducing the risk of intestinal disease, cardiovascular disease, and diabetes [10][11][12]. Studies on protein-polysaccharide composite gels have revealed that these composite gels elicit better functional performance and stability than the single component gel [13,14].…”
