Lactic acid bacteria, also known as lactobacillus or lactobacilli, are the main components of yogurt and are also resident bacteria in the human intestine, mainly found in the middle and lower parts of the small intestine. The benefits of lactic acid bacteria for health are numerous, and they can be rightly called "beneficial bacteria that do no harm". They are highly regarded and loved, second only to bifidobacteria, just like the handsome and capable White Dragon Horse in the Chinese classic "Journey to the West". What are the functions of lactic acid bacteria?
Promoting infant growth
Many babies lack lactic acid bacteria in their bodies, and they may experience diarrhea after drinking milk. This is mainly caused by lactose intolerance, which makes it difficult to absorb the nutrients in milk. Taking an appropriate amount of lactic acid bacteria can naturally cure or alleviate the symptoms of diarrhea. In addition, lactic acid bacteria can also synthesize vitamin B, which is beneficial for the development and growth of infants.
Improving intestinal environment
Lactic acid bacteria are beneficial for the growth and reproduction of normal intestinal flora, and can improve the metabolism, digestion, and absorption functions in the intestine. The metabolites of lactic acid bacteria include many organic acids, among which lactic acid is particularly important. It can lower the pH value in the intestine, increase acidity, and create a favorable metabolic environment in the intestine.
Enhancing immune function
Lactic acid bacteria are resident bacteria in the intestine and have a significant stimulating effect on the formation of mucosal immunity. Mucosal immunity is an important defense system of the host and a stimulating factor for splenic lymphocytes and thymic immune centers. Research by Swedish scientists has shown that plant-derived lactic acid bacteria can not only regulate the intestinal flora, but also have immune-enhancing effects.
Anti-aging effects
In older people, the intestinal flora undergoes changes, with a decrease in lactic acid bacteria and bifidobacteria. The intestinal contents gradually become alkaline, allowing harmful bacteria such as gas-producing clostridia, proteus, and pseudomonas to take advantage and produce many toxic metabolites, putting humans in a state of mild chronic poisoning. Taking lactic acid bacteria products (such as yogurt) at this time can reverse the trend of decreasing acidity in the intestinal contents, increase acidity, reduce harmful bacteria, remove intestinal waste, improve digestion and absorption, and enhance overall health, thereby achieving the effects of longevity and anti-aging.
