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.

Tis the season for overeating. But it's not just your lack of willpower, or the omnipresent holiday treats.

No, you can lay some of the blame on Gorellan, because a new study shows that grelin, the hormone that makes you hungry, also makes food, and food smells,

irresistibly appealing. The finding appears in the journal Cell Reports. Grelin is produced in the

stomach, and its levels rise before your habitual meal times and after you haven't eaten for an

extended period. So the hormone reminds you to put something in your belly.

Injecting rats with girellin encourages them to eat, and people who receive a dose of girellin grab extra helpings from the buffet. But how does the hormone induce overindulgence?

To find out, researchers at McGill University trained volunteers to associate random images

with the smell of food.

For example, every time they saw a tree, they might get a whiff of freshly baked bread.

At the same time, some of the subjects received Grelin.

Others got only saline.

The volunteers were then ushered into an fMRI machine, where the researchers watched their brains

to see which parts got turned on

by different images. Seems that in subjects under the influence of Gorellan, the brain region

involved in pleasure and reward lit up only when the volunteers viewed the images they

associated with food aromas. Their brain pleasure centers were disinterested in images
