GUT microbes is a buzz-word in medical fraternity of western world. It is welcome sign as they are unlearning useless DNA dogma and mindless antibiotic treatment practices.
In Bharat(India), child development is intervened in वर्णाश्रम धर्म. Everyone was following it 100 years back. And it was very reason why we were never worried about health by minor details like GUT microbes.
वर्ण & आश्रम were potent tools to take care and nurture पंचकोशीय बंधारण. As soon as you hit the age of Upanayan, you are sent to forest for learning. It is very essential.
In many countries, they are shifting schools to forest. Forest-school is growing concept in finland, japan and US. (Google it to know more).
Our गुरुकुल शिक्षण happened in forest. Forest and cows were prerequisites. Both act as प्राणवर्धक & प्राण-संवर्धन.
When GUT-microbes of growing kids are not taken care (unfortunately, me and many in my generations missed it. Present generation of urban kids are missing it. Present generation of rural kids also miss it due to urban influence but they are still in good position compare to urban kids), adult life is miserable, feeble and weak.
Why Worry about Children’s GUT health?
The role of gut microbiota in early life and its impact on gut health and subsequent diseases remain unclear. There is a lack of research and awareness in this area, especially in the Asia‐Pacific region, including Malaysia. This paper reports the position of a Malaysian Working Group on some key issues surrounding gut microbiota in early life and its role in gut health and diseases, as well as experts’ stand on probiotics and prebiotics. The group reached a consensus that certain factors, including elective caesarean; premature deliveries; complementary feeding; use of antibiotics, prebiotics and/or probiotics; and exposure to the external environmental, have an impact on gut microbiota in early life. However, as evidence is lacking, especially from the Asia‐Pacific region, further studies are needed to understand how gut microbiota in early life affects subsequent diseases, including allergy, inflammatory bowel disease, obesity and infantile colic. Lastly, although beneficial in acute diarrhoeal disease and probably allergic eczema, probiotics (and/or prebiotics) should be used cautiously in other gut dysbiotic conditions until more data are available.

Switching from an Urban to Hunter-Gatherer Lifestyle may Increase Diversity in Children’s Gut Microbes
An international team of researchers has shown that immersing city dwellers in the traditional lifestyle and diet of a rainforest village for two weeks increases the diversity of the visiting children’s—but not the adults’—gut microbiota. In a small pilot study published this week in mSphere®, an open-access journal of the American Society for Microbiology, the team shows that the immersion visit did little to shift the adults’ skin, oral, nasal and fecal microbiota.
“We wanted to look at the question of whether microbiota change during a drastic, radical change of diet and lifestyle,” says Maria Gloria Dominguez-Bello, a microbial ecologist at Rutgers University in New Brunswick, New Jersey who led the study with microbiologist Monica Contreras from the Venezuelan Institute of Scientific Research. “In this village, there was no market economy, no bodega, no Coca-Cola—so this represented a radical shift in diet from a high percentage of processed foods in urban places to zero processed foods and an all-natural diet.”
Dominguez-Bello, along with researchers from New York University and two Venezuelan institutes, took advantage of a visit planned by five, city-dwelling adult visitors—and two of their children—to live among an indigenous Yekwana village in the Bolivar State of Venezuela for 16 days. The village has a hunter-gatherer-gardener lifestyle and diet.
Typical fare includes cassava (a starchy, high-fiber tuber), corn, various wild fruits, including plantains, pineapples, and berries, fish, and small amounts of game meat and eggs gathered from wild birds. Visitors had two meals a day that consisted of soup with a bit of fish or meat. The rest of their diet consisted of “all-day snacking on cassava with fruit” says Dominguez-Bello. The visitors also bathed in the river without soap and followed the natural circadian rhythms of their hosts.
“The diet contains very little animal protein and it’s very, very high in fiber and very low in fat,” compared to Western diets, says Dominguez-Bello.
While it is known that people with traditional diets have higher gut microbiota diversity compared to those with urban diets, it was unknown if urban dwellers could shift the diversity of their microbiota higher simply by following a traditional lifestyle and diet. In the gut, a high diversity of microbes is considered a sign of good health.
Traditional people eat diets rich in unprocessed plant material, which are much more chemically complex compared to processed foods. The smorgasbord of chemicals acts as fuel for a higher variety of microbes. Traditional people use less antimicrobial medicines and compounds in daily life, which might also contribute to their increased gut microbe diversity.
During the 16-day visit, the researchers collected samples from the visitors’ skin, mouth, nose, and from a fecal swab. Age-matched samples were also collected from villagers. The samples were sequenced and compared.
Surprisingly, none of the adult visitors’ microbiota shifted significantly during the visit, while the two children’s gut microbiota trended toward a higher number of total microbial species present. Although these results were not statistically significant and in just two subjects, the researchers saw this as interesting nonetheless, given the children’s ages of 4 and 7.
Up to now, it was thought that children’s gut microbiota become stable and more ‘adult-like’ by the time they reach 3 years of age. “This indicates that the window for maturing your microbiome may not be 3 years of age, but longer,” says Dominguez-Bello. Her team plans to do a larger study with 12 children participating in an “immersion summer camp” to a traditional village.
Because the children’s gut microbiota exhibited more plasticity, these results raise an interesting possibility that urban children who eat a more traditional, high-fiber, low-fat and low-processed diet early in life might cultivate a more diverse set of gut microbes. Conversely, adults may have a limited response due to their low microbiome plasticity.
Dominguez-Bello was not terribly surprised that the adults’ gut and other microbiota changed so little: “If you take traditional people and bring them to New York, give them antibiotics and McDonald’s to eat everyday, it’s not surprising that they lose diversity,” she says. “But if, as an urban dweller, you’ve already lost that gut microbe diversity and you move to a high-diversity diet, maybe you cannot ‘bloom’ diversity because you simply don’t have those microbes present anymore.”
