1. It’s your serotonin factory. For all of its importance to mental well-being, you might expect that the brain is where we find most of the body’s serotonin, but it’s not. In fact, the gut contains the vast majority of the serotonin in our body. Kefir is one of the only foods on the planet that delivers this twofold benefit of supporting our serotonin factory aka gut with probiotics and delivering a dose at the same time!
2. A healthy gut strengthens the immune system.
This is because the gut microbiome and the immune system work together, stimulating and modulating each other. In other words, a balanced immune response requires a balanced microbiome.
3. A healthy gut prevents “Leaky Gut”
A permeable intestine, also known as a “leaky gut”, allows undigested macro-molecules, pathogens, antigens, and toxins to pass freely into the bloodstream from the intestine, contributing to the body’s toxic load and, of course, inflammation.
4. A healthy gut promotes healthy weight.
In addition to increasing nutrient absorption and synthesizing certain vitamins, gut bacteria affect how individuals hold on to weight. Certain bacteria actually promote obesity.
The health of the gastrointestinal tract may also regulate insulin sensitivity and determine whether to store food as fat, or use it for energy.
