Bifidobacterium: Protection from day one

Bifidobacterium is a genus of bacteria that plays a key role in maintaining a healthy gut microbiota. These bacteria are commonly found in the intestines of humans and animals, as well as in fermented foods such as yogurt and supplements. Bifidobacterium species are among the first to colonize the human gastrointestinal tract shortly after birth, particularly in breastfed infants who acquire them directly from their mothers.

In the human gut, Bifidobacterium bacteria contribute to digestive health by breaking down complex carbohydrates, fibers, and sugars that are otherwise indigestible. In the process, they produce short-chain fatty acids, such as acetic and butyric acids, which are crucial for maintaining gut health. Short-chain fatty acids provide energy to colon cells, promote gut barrier integrity, and reduce inflammation, all of which are important for preventing various gastrointestinal disorders.

One of the main roles of Bifidobacterium in the gut is to maintain a balanced and healthy microbiota by outcompeting harmful pathogens. By lowering the pH in the gut through the production of lactic acid and acetic acid, they create an environment less favorable for the growth of harmful bacteria, helping to prevent infections and promote overall gut health.

The beneficial effects of Bifidobacterium include improved digestion and nutrient absorption, as well as enhanced immune system function. These bacteria help reduce inflammation in the gut and have been linked to relief from conditions such as irritable bowel syndrome, inflammatory bowel diseases, and diarrhea, particularly in children. Bifidobacterium is also known to reduce symptoms of lactose intolerance and may play a role in preventing allergies and eczema.

Regular intake of Bifidobacterium-rich foods or probiotics supports a balanced gut microbiome, strengthens immune defenses, and promotes overall digestive health, making these bacteria essential for maintaining well-being across different life stages.

Japanese people have a taste for healthy food deeply rooted in their ancient culture and cuisine. Despite Japan not being among the world's top dairy consumers, it has a longstanding love for Bulgarian yogurt. Since 1972, when Bulgarian lactobacilli strains were first imported into the country, the Japanese conglomerate Meiji Holding has been manufacturing Bulgarian yogurt.

Today, these probiotic products are consumed by over 40 million Japanese citizens, making up an impressive 38% of the population.

This LB-backed dietary tradition has become synonymous with robust health and longevity.

From a research perspective, Meiji established Meiji Dairies Corp. to advance its expertise in probiotics. Over the years, it has conducted more than 350 clinical trials and patented numerous potent strains. Meiji now produces 700 tons of yogurt daily across its 29 factories and distributes 32 dairy products containing Bulgarian bacterial species.

Since 1972, when LB yogurt first appeared in Japan, the country's life expectancy at birth has increased by almost 20% (16.3 years). In light of this, it is plausible to hypothesize a correlation between the increased life expectancy of the Japanese population and the health benefits of probiotic yogurt.
