 this is scientific american 60 seconds science. i'm (name). got a minute? this thanksgiving as you savor 1 your turkey in stuffing, you have something else to give thanks for: the army of microbes that help you digest the feast.cause when you eat you are feeding them too, and triggering an enormous bloom of gut 2 bacteria. in fact as many as a billion new ecoli bacteria may come into being during one of those feeding frenzies 3, but 20 minutes after the population explosion begins, the bacteria reach critical mess and put on the brakes. and when they enter that resting state, they start pumping out a particular sweet of proteins. researchers harvest those post pamdio protein from ecoli and add them to the ecoli of rats. and the proteins appear to interact with the andiqun cells in the gut, flapping on the production of hormones 4 and tell the brain:" hey, stop eating. we're full." meanwhile, mice injected with ecoli proteins over the course of a week ate less of each meal. though they compensate 5 by eating more often. all of which suggests that the proteins product by bacteria can influence and even interference with our sense of feeling stuffed. the study is in the journal "cell metabolism 6". as far as overeating girls, the researchers say we probably won't inject people with bacteria appetites presence any time soon, but it might be worth paying closer attention to the health and composition of our gut bacteria. since they do appear to play in a role of regulating our eager to eat. so as you are stuffing yourself with stuffing on Thursday, you might ask yourself :"what would my gut bacteria want?"
