To ancient things. A new study is pop. The is a japanese study and his japanese study was looking at a group of japanese centenarians. Who seem to have these seemingly magical powers. They have an average age of one hundred seven amongst the healthiest longest living humans on earth protected from chronic diseases that that inevitably haunt a lot of the rest of us as we age like obesity and diabetes hypertension and cancer. But what they found these people that really stood out was the trillions of microbes that lived in their gut It wasn't the amount of the microbes but it was. It was the composition of those gut bugs. The composition of those gut bugs basically. They had a bacterial signature. Those similar to the strains of bacteria in in each and every single one of the centenarians but a lot of them had a very similar microbiome in one strain in particular stood out and it was type of bile acid. Okay or is it a bacteria that synthesizes bile acid now bile acids what you might know. Is this kind of boring bodily fluid that's commonly known for digesting fats. But it's now being called as a class of entering hormones hormones that go beyond their classic role in fat digestion and absorption. So what they found. Is that these bile. Acids helped to protect sensitive gets infection and other environmental stressors. So it's really interesting because we know that that the gut bile acid content to decrease a little bit as one ages in the secondary by lasts a really powerful so they've done studies in mice before they looked at the these these microbiomes humans and they found that the gut bile acids to regulate immune cells and prevent some dangerous microbes from taking over the gut. And what a what they looked at in the seniors a particular group of gut bugs called or owed oral back to rasaie adora backdoor and that turned out this little bile acid called eyeso- aloe lithocholic acid or eyeso- aloe
