Dietary fiber has long been recognized for its role in digestive function. However, currently there is scientific debate about definitions (descriptive and analytical), optimal intake, and essentiality in the human diet. Dietary fiber is a key substrate for bacterial metabolism in the colon, which makes research on dietary fiber an important issue that complements current interest in the gut microbiota. Dietary fiber is also important for prevention and management of cardiovascular disease, diabetes, obesity, and other chronic diseases. This Special Issue will highlight recent research on dietary fiber content in foods and function in human health, ranging from digestive function to chronic disease prevention and management.
Una perspectiva ética al problema de la gestión y el uso de recursos sanitarios, ya que no es sólo un problema técnico , jurídico o político.
Diet and lifestyle choices can substantially predispose an individual to, or protect against, many age- and obesity-related chronic diseases. According to the NIH Office of Dietary Supplements, dietary bioactives arecompounds in foodsnot needed for basic human nutrition but responsible for changes in health status.1 These compounds are safe at normal food consumption levels (e.g., anthocyanins in berries) and their biological activities may come from a single compound (e.g., lutein in spinach) or a class of compounds (e.g., avenanthramides in oats) even if the exact identity and composition are unknown. Bioactive compounds of plants; can vary significantly in their ratios and relative concentrations depending onfactors such as cultivation, soil, altitude, and weather conditions. Substantial scientific evidence is available for some health promoting phytochemicals, such as dose-response relations, for performance and/or reduction in the risk of chronic disease. However, several limitations relating to absorption, distribution, metabolism and excretion of many dietary bioactives still exist and must be better
