Wheat bran is a major by-product of white flour milling and had been produced in large quantities around the world; it is rich in dietary fiber and had already been used in many products such as whole grain baking or high dietary fiber addition. It has been confirmed that a sufficient intake of dietary fiber in wheat bran with appropriate physiological functions is beneficial to human health. Wheat bran had been considered as the addition with a large potential for improving the nutritional condition of the human body based on the dietary fiber supplement. The present review summarized the available information on wheat bran related to its dietary fiber functions, which may be helpful for further development of wheat bran as dietary fiber resource.

With the development of living standards, harmful substances in diet and food safety have seriously endangered people health and life. Advanced glycation end products (AGEs), which formed by Maillard reactions in processed food, have been shown a significantly associated with many chronic diseases, such as nephropathy, atherosclerosis, Alzheimer’s disease, and tumors. In recent years, the research about diet advanced glycation end products (dAGEs) have widespread controversy in academia. The main arguments include the production mechanism of dAGEs, metabolic pathways, and relationships with chronic diseases, especially related to the intestines, gut microbiota, and intestinal disorders. So this review attempts to briefly summarize the dAGE in following aspects, including the influencing factors, metabolism, absorption, and so forth. In addition, the effects of dAGEs on intestinal health and gut microbes were discussed, which can offer a goal for boff in to design low dAGEs products and provided some perspectives for further study with AGEs in the future.

Oat β-glucan supplementation ameliorated DSS-induced colitis concurrently through regulating gut-derived SCFAs and intestinal microbial metabolic profiles.
