Bifidobacterium is one of the predominant beneficial bacteria in the human intestine. In healthy breast-fed infants, the intestinal microbiota is more than 90% composed of Bifidobacterium. Bifidobacteria function in maintaining health and preventing infection for infants.
The generally used probiotic bacteria are categorized into two groups: the Bifidobacterium species and the Lactobacillus species.
Lactobacillus, one of lactic acid bacteria, is known for being able to convert carbohydrates into lactic acid. Lactic acid has the capability of destroying disease-causing bacteria or pathogens.
Besides converting carbohydrates into lactic acid, bifidobacteria also produce acetic acid, a substance that has a strong bactericidal property and is thought to suppress the growth of harmful bacteria.
Acetic acid produced by bifidobacteria can speed up the contractions of the stomach that push pathogens out of the body system in stool.
Between 7 to 10 days from birth, accompanying feeding by breast milk, a healthy infant's intestinal microbiota is more than 90% composed of Bifidobacterium. However, the amount of probiotic bacteria in the human body varies dramatically with age. Although infants have a very high number of bifidobacteria in their system, this number decreases substantially as putrefactive bacteria increase. Consider the chart below indicated the decrease in Bifidobacterium ratio to intestinal putrefactive products for an adult of only 24 years old:
(Study by Morinaga)
At Morinaga we believe that the dominance of bifidocteria in the human gut and their ability to produce both lactic and acetic acid makes them a superior probiotic with more functional health benefits. Thus, the focus of our research for the past half a century has been on Bifidobacterium specifically.
