Health Benefits of Eating Lacto-fermented Foods
The benefits of fermented foods start with the growth of the bacteria strain lactobacilli during the fermentation process. This type of healthy bacteria enhances digestibility and increases vitamin levels. Lactobacilli convert the starches and sugars of the vegetables into lactic acid which is a natural preservative. It prevents the growth of harmful bacteria while keeping the pH level favorable to good bacterial strains.
One of the great benefits of eating fermented foods is how their enzymes aid in the digestion of the food as you eat them.
