Research found the following difference in stomach microbes of different individuals:<ul><li>Intestinal microbes of people living in villages, having a natural diet, are much more complex, and can degrade fiber.</li><li>People in cities, eating a western diet, have microbes in their stomach adapted towards processing protein, fats, and sugars.</li></ul>

Microbes

Due to the new kinds of microbes discovered in villagers, all the previous research on diet and microbes, which used the baseline data of the Western civilization microbe, thought to be the healthy and normal microbe, is now incorrect.

Wrong Baseline Data

Americans consume less fiber than what is recommended, eating fewer nuts, whole grains and fruits and vegetables.A fiber-rich balanced diet is known to prevent colon cancer, diabetes, and heart disease.

Fiber-Rich Diet

Regular poor diet leads to a rise in endotoxins in our bloodstream, making the immune system respond to this by inflammation.Chronic inflammation, every time we eat junk food, leads to cellular dysfunction and diseases of the stomach and organs.

Chronic inflammation 

The Western world has stomach microbial communities that could digest junk food and might re-diversify and recover (to a limited extent) if we just ate more whole grains and veggies.

Digesting Fibre

Westerners who grew up in villages, in farms, living among livestock at a ranch, or are exposed to certain infections at an early age, tend to have a lower risk of autoimmune diseases.

A Stronger Immunity 

The microbial die-outs, a form of mutation inside our stomach due to our specific diets, gets compounded across generations.This is leading to a sort of internal 'extinction' of microbes, which were abundant inside our ancestors, but are not present in us.

Internal Extinction

As Western civilization fails to nourish key microbes, the type of food taken is starving them out of existence. Many factors cause this:<ul><li>Antibiotics 'nuke' our internal ecosystems, killing all good microbes.</li><li>Sanitary facilities of the modern age prevent the sharing of disease, along with health-promoting microbes.</li><li>City life limits our exposure to soil, plant and animal microbes.</li></ul>

Microbial Extinction

As the Medical and Pharma industries get equipped with better research and technology, there should ideally be a decline in diseases. Instead, we have an increase in non-communicable diseases.This rise can be blamed partly to the microbial extinction inside us, altered by Sanitation, Antibiotics and Junk food.

New Kinds of Diseases

For the microbiologist Justin Sonnenburg, that career-defining moment-the discovery that changed the trajectory of his research, inspiring him to study how diet and native microbes shape our risk for disease-came from a village in the African hinterlands. A group of Italian microbiologists had compared the intestinal microbes of young villagers in Burkina Faso with those of children in Florence, Italy.
