Effects of Polyunsaturated Fatty Acids on Human Health Through Intestinal Microbiota

Unsaturated fatty acids act a necessary part in the intestinal health of the host microbiota environment and immune ability by being transformed by intestinal microorganisms. Polyunsaturated fatty acids (PUFAs) are very important to the host body, also they influence many physiological activities of the body. The amount of polyunsaturated fatty acids synthesized by the human body cannot meet the daily needs of the human body, and it is necessary to obtain some essential fatty acids (EFA) from food. At the same time, some intestinal microorganisms can also synthesize and convert polyunsaturated fatty acids, which contribute to the regulation and control of host immunity. In addition, PUFAs are also beneficial to humans. They are critical in sustaining a healthy and stable gut microbiota environment and regulating and controlling host immunity. This paper summarized the conversion mechanism and effect of intestinal microbiota on polyunsaturated fatty acids, discussed whether polyunsaturated fatty acids can regulate human diseases and microbiota as health products, and determined the regulatory mechanism of polyunsaturated fatty acids.
