Nature: Eat more vegetables for healthy intestinal flora.  Researchers also found that gut microbes are associated with the risk of obesity, cardiovascular disease and type 2 diabetes.

Microorganisms are everywhere. They are parasitic on our skin, genitals, oral cavity, especially the intestines. Joshua Lederberg, winner of the Nobel Prize in Physiology or Medicine, once said that microbes that live in symbiosis with the human body constitute super organisms.

As the human body’s largest and most complex intestinal microecosystem, its own and its metabolites not only regulate human health, but also play an important role as a bridge between diet and the host. Therefore, research on intestinal microbes has attracted much attention.


Recently, researchers from the University of Trento in Italy, King’s College London and the Harvard School of Public Health jointly published a long-term follow-up article titled “Microbiome connections with host metabolism and habitual diet from 1,098 deeply phenotyped individuals” in Nature Medicine. , Found that eating plant foods and healthy eating habits will encourage the existence of beneficial microbes in the intestines and reduce the risk of obesity, diabetes and other diseases.

This study selected 1,203 gut microbiomes from a total of 1,098 subjects from the United Kingdom and the United States, collected basic personal information, habitual diet data, and physical health of the subjects, and passed the metagenomic sequencing of stool samples Analyzing the relationship between their gut microbes, eating habits and health, the test results show that the gut microbiome is closely related to various foods, and the strongest connection is coffee.

The relationship between different foods and the gut microbiome

Researchers define “healthy” food as a food mixture that is associated with a low risk of chronic diseases. They found that subjects who ate this food and edible plant-based food had higher levels of beneficial gut microbes, on the contrary, highly processed plant-based foods. Food diet is more likely to be related to harmful gut microbes.

In addition, researchers have also found that gut microbes are associated with the risk of obesity, cardiovascular disease and type 2 diabetes. Surprisingly, the gut microbiota is associated with this type of metabolism compared with other factors such as genetics. The disease is even more connected.

In the process of exploring the link between gut microbes and type 2 diabetes, the researchers also found that the microbiota rich in Prevotella and Blastocystis is related to maintaining good blood sugar levels after meals.

Dr. Sarah Berry from King’s College London said: “As a nutrition scientist, it is exciting to discover new types of microorganisms related to specific foods and metabolic health. Given the highly personalized composition of each person’s microbiome, research shows that we It may be possible to change the gut microbiome by choosing the most suitable food for humans to optimize our health.”
