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.

We all know that stuffing our faces with sweet treats is not good for us, in part because

it's bad for the health-promoting bacteria that inhabit our intestines. Now, researchers have figured

out how simple sugars wipe out a particular strain of beneficial gut microbes.

The underlying assumption that existed in the literature was that simple sugars such

as fructose and sucrose, which are prevalent in the Western diet, are not good for humans.

Yale professor of microbial pathogenesis, Eduardo Greism, who led the study.

Simple sugars, like those in high

fructose corn syrup or the table sugar formerly known as sucrose, were thought to be absorbed in the

small intestine, so a lot of our gut bacteria would never actually be exposed to them. Because fiber

and complex carbs, made of long chains of sugar molecules, are harder to digest.

They make it all the way to the large intestine, where they promote the growth of good bugs,

like bacterioids, theta-iota-o-micron, a microbe found in individuals who are healthy and lean.

But now, what our work actually shows is that both fructose and sucrose do make it to the column,

where the microbiota exists, and second, that these sugars impact a good bacterium

even though nutrition is not involved. In other words, the bacteria are not using fructose

and sucrose as food. Instead,
