Among the microorganisms in the body, the largest number of microorganisms inhabit the intestine. There are more than 4,000 to 10,000 types of intestinal microbes, and about 70% of immune cells that influence immunity are distributed. About 30% of beneficial bacteria exist in the gut microbes, which are called probiotics, and beneficial bacteria account for 5 to 10%. Among microorganisms that help us maintain health, Lactobacillus and Bifidobacterium are representative. Probiotics play a decisive role in increasing the proportion of beneficial bacteria in the microbiome, the total microflora in our body. Probiotics are beneficial bacteria that form the intestinal barriers, regulating intestinal acidity, regulating human immunity, and generating antibacterial substances. When the balance of the intestinal microflora is disturbed, the health of the gut deteriorates, and at this time, the virus accesses the inside of the intestine and is exposed to various diseases. When chronic disease or infection becomes severe, it can be considered unhealthy intestinal microflora.
According to a Japanese paper approved by the ethics committee of Yamanashi University, drinking alkaline water containing hydrogen for 2 weeks increased the number of Bifidobacterium and improved gastrointestinal symptoms. 20 male participants aged 30-59 years old were given alkaline water containing hydrogen for 2 weeks. Thus, hydrogen dissolved alkaline water may promote the growth of beneficial bacteria in the intestine and gastrointestinal tract.
A team of researchers from the University of Minnesota in the United States observed for nine months how changes in diet affect the gut microbiota. The research team confirmed that the diversity of intestinal microbial species decreased when subjects on a healthy vegetarian diet consumed westernized foods. Prevotella, which is found a lot in vegetarians, in particular, decreased. Instead, they found that Bacteroides were turning into microbes specific to a westernized diet.
The United States is a typical fast-food country, and refined wheat is the staple food, and there are many foods rich in processed fructose and protein. With fast-food eating habits, the diversity of the gut microbiome decreases, and the microbiome imbalance increases the number of harmful bacteria in the gut. Inflammation occurs with toxins produced by harmful bacteria, and when inflammation worsens, it metastasizes to other organs through blood vessels. It can treat various diseases such as sepsis, brain disease, immune disease, and cardiovascular disease.
As in social factors, the higher the economic status, the more prosperous Bacteroides and the less prosperous Prevotella. Even if you are not poor, you cannot have negative health consequences, but statistically, the results were not good in poor neighborhoods, and it was found that it also affects the state of health. It also affects the environment for exercise, the distribution of fresh food retail outlets, and exposure to air pollution and crime. The more prosperous the neighborhood, the more animal fat intake was relatively abundant, so the intestinal microbes contained more Bacteroides and low Prevotella. Often, there are factors that hinder intestinal bacterial diversity, such as processed foods, abdominal obesity, lack of physical activity, and excessive use of antibiotics.
