A healthy gut barrier depends on cooperation between different groups of microbes. Lactic acid bacteria and bifidobacteria help stimulate mucus production and maintain a stable surface environment along the intestinal lining. When this mucus layer is strong, it reduces direct contact between bacteria and gut cells.

Lactic acid bacteria are among the most important microbes in food fermentation and gut health. They are called “lactic” not because they come from milk, but because they produce lactic acid as a result of fermentation.

Milk looks simple, but it is one of the most complex foods we consume. When milk is fermented, it doesn’t just become thicker or more acidic — it is fundamentally transformed. Fermentation changes the structure of milk proteins, the sugar content, and how the body interacts with it during digestion.
