Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

This Thanksgiving, as you savour your turkey and stuffing, here's something else to give thanks for.

The army of microbes that help you digest the feast. Because when you eat, you're feeding them too,

and triggering an enormous bloom of gut bacteria. In fact, as many as a billion new E. coli bacteria

may come into being during one of those feeding frenzies. But 20 minutes after that population

explosion begins, the bacteria reach critical mass and put on the brakes. And when they enter

that resting state, they start pumping out a particular suite of proteins.

Researchers harvested those post-pranial proteins from E. coli, and added them to the

colones of rats. And the proteins appeared to interact with endocrine cells in the gut,

flipping on the production of hormones that tell the brain, hey, stop eating. We're full.

Meanwhile, mice injected with the E. coli proteins over the course of a week

ate less at each meal, though they compensated by eating more often. All of which suggests that the

proteins put out by bacteria can influence and even interfere with our sense of feeling stuffed.

The study is in the journal Cell Metabolism. As far as overeating goes,

the researchers say we probably won't inject people with bacterial appetite suppressants

anytime soon. But it might be worth paying closer attention to the health and composition of

our gut bacteria, since they do appear to play a role in regulating our urge to eat.
