Fermentation adds microbes to food and drinks for preservation purposes. The good bacteria and yeast consume the sugars in the edibles. They continue to do this once they reach the host's gut, thus aiding the digestive process.

Eating fermented foods supports a healthy gut microbiome. They help replenish the population of good bacteria and other beneficial microorganisms in the body.

In turn, gut health contributes to the general health of a person. A healthy gut seems to lead to a happier person.

The good bacteria and yeasts found in fermented foods serve as probiotics. They bolster the health of the gut.

Some diseases come from an imbalance in the gut microbiome. Eating probiotic foods will help improve the following diseases:

Bacterial infection

Antibiotic-related diarrhea

Infectious diarrhea

Ulcerative colitis

Irritable bowel syndrome

Crohn's disease
