Dietary fibre complexity and its influence on functional groups of the human gut microbiota

The aim of this review is to provide an overview the complex interactions between dietary fibre and resident microbial community in human gut. microbiota influences both health maintenance disease development. In large intestine, plays a crucial role degradation carbohydrates that remain undigested upper gut (non-digestible or fibre). Dietary contains variety different types carbohydrates, its breakdown facilitated by many enzymes. Some microbes, termed generalists, are able degrade range whereas others more specialised. Furthermore, physicochemical characteristics fibre, such as whether it enters soluble insoluble form, also likely influence which microbes can it. A nutritional network therefore exists comprising primary degraders attack cross feeders benefit from intermediates fermentation products. This leads predominately generation short-chain fatty acids (SCFA) acetate, propionate butyrate, exert various effects on host physiology, including supply energy, influencing glucose lipid metabolism anti-carcinogenic anti-inflammatory actions. order effectively modulate through diet, there need better understand competitive cooperative breakdown, well how environmental factors state originating diets ecology
