　　Australian researchers have found that high-fiber food can enhance the immunity of laboratory mice and increase the survival rate of laboratory mice infected with influenza virus.

　　Researchers from Monash University in Australia published a report in the American Journal of Immunity that they found through animal experiments that high-fiber foods can activate white blood cells, enhance the immunity of experimental mice, and help them resist influenza viruses. The researchers said that the reason for the dual effects of dietary fibers may be that they help change the composition of the intestinal flora and increase the production of short-chain fatty acids, which can provide energy for cell growth and help eliminate inflammation.

　　Benjamin Maslan, who participated in the study, said that some specific therapies will make our immune system either "fire-powered" or completely shut down. Surprisingly, dietary fiber will "selectively" shut down part of the immune system. , And open another part.

　　Researchers will focus on exploring the exact mechanism of dietary changes affecting the immune system, and studying what dosage and type of dietary fiber can maximize human immunity.

　　Foods rich in dietary fiber include oats, black beans, lentils, red kidney beans, whole wheat pasta, brown rice, Brussels sprouts, flaxseed, raspberries, dried figs and almonds. Researchers believe that modern Western diets are generally high in sugar and low in fiber, which is not conducive to improving the body's immunity.
