There is no difference. Lactic acid bacteria are probiotics. Lactic acid bacteria is a kind of probiotics existing in human body. Lactic acid bacteria can ferment carbohydrates into lactic acid, hence the name. Probiotics can help digestion and contribute to the health of human intestines, so they are often regarded as healthy foods and added to yogurt.

Extended data

Lactic acid bacteria are also widely found in the intestines of livestock and poultry, many foods, materials and a few clinical samples. Lactic acid bacteria can not only improve the nutritional value of food, improve the flavor of food, improve the preservation and added value of food, but also attract more and more attention for its special physiological activity and nutritional function.

A large number of studies show that lactic acid bacteria can regulate the normal flora of gastrointestinal tract, maintain microecological balance, improve food digestibility and biological value, reduce serum cholesterol, control endotoxin, inhibit the growth and reproduction of spoilage bacteria in intestinal tract and the production of spoilage products, make nutrients, stimulate tissue development, and thus have an effect on the nutritional status, physiological function, cell infection, drug effect, toxic reaction, immune reaction, tumorigenesis, aging process and sudden emergency response of the body.

Internationally recognized lactic acid bacteria are considered as the safest strains and the most representative intestinal probiotics. The more probiotics represented by lactic acid bacteria in human intestines, the better. It is also completely in line with the conclusion drawn in the "longevity theory" of Nobel Prize-winning biologist Mechnikov, that lactic acid bacteria = probiotics = longevity bacteria.
