Elie Metchnikoff, a Russian zoologist who is considered by many to be the father of probiotics, discovered in the 20th century that Bulgarian peasants were remarkably healthy for being so impoverished. The reason? They drank sour milk, which happened to be full of probiotics.
Metchnikoff later discovered that probiotics were the heroes here, as they helped to strengthen both the intestines and the immune system.

It turns out your stomach and attitude are more connected than most of us realize. “Our immune system and our brain chemistry are among some of the most important reasons why we need to keep our digestive system healthy,” Dr. Donese Worden, a naturopathic medical doctor, told us.
“Many of our immune cells are made and instructed by our gut. That’s why we tend to get sick when we’ve had an emotional upset.
On the flip side, we can become depressed if our GI is not working well because the majority of serotonin is made in the gut.”
Dr. Krista Casazza, an associate professor at the University of Alabama at Birmingham, provided further insight. “The brain’s reward system, including mood and mental health, is wired for feedback with the gut, which is dependent on healthy flora… In health, the gut profile promotes feedback that aligns with energy balance, glucose, and lipid homeostasis, and positive mood.”
