Probiotics may not be beneficial, according to the study

take antibiotics or have gastrointestinal problems, many people will be anxious to drink a few cups of probiotics to restore the "natural balance" of gut microorganisms. Probiotics have become one of the fastest growing products in the food industry and are now integrated into yogurt, beverages and children's food. However, not everyone needs probiotics to stay healthy. A new study of gut bacteria in African hunter-gatherers has revealed that they do not have a key bacterial component in most probiotic foods, but remain healthy. Moreover, the world's only remaining hunter-gatherer tribe, the Tanzanian
Hadza
, does not have colon cancer, colitis, Crohn's disease or other colon diseases caused by modern Western eating habits.project is the first study of gut bacteria in hunter-gatherers. Previous studies have focused on industrialized countries, where eating habits tend to be high in sugar, salt and fat. These eating habits change the type of bacteria in the gut - the microbiome. Gut bacteria quickly adapt to host dietary changes, and the microbiome of residents living in rural areas and eating less processed foods is more diverse. The researchers also found a link between microbial diversity and colon disease.study took stool samples from

ethnic groups and sent them to the University of Bologna in Italy in the form of frozen or dry samples specializing in extracting and sequencing

from bacteria. The team identified the bacteria through

and analyzed the types of nutrients in the faeces, including microbial metabolites, which are the source of energy for gut bacteria.when the team compared

between Hadza and Italians, they found that
Hadza
s gut microbial ecosystem was more diverse. Moreover, compared to bacteria in two groups of farmers in Africa, they found that only
Hadza
people did not have the most common bacteria in probiotic beverages, Bifidobacteria, possibly because the group did not consume dairy products.Hadza
people also have high levels of bacteria such as dense helix, which is a sign of disease in Westerners, as different types are associated with systemic lupus erythematosus, periodontitis and syphilis. However,
