The food diversity present in American guts is by no means a representation of the cultures found within the country. Their guts are no different from that of persons in Venezuela or rural Malawi. A new study has revealed that the microbes present in westerners’ guts are due to the protein-rich diet that they consume. This is because the American population has guts that are adapted to meat diets characterized by the food they eat.
Microbes, singular for the population of bacteria called microbiomes, boom in the body, outnumbering human cells by a ratio of 10 to 1. These microbiomes play a vital role in the breaking down of some nutrients found in one’s diet in order to turn them into a form useful to the human body. Researchers suspect that microbiomes also determine how vulnerable one is too certain diseases.
For a scientist to test their hypothesis, they needed to see how healthy adult microbiomes look like.Gastroenterologist Jeffrey Gordon and his colleagues from the Washington University in St. Louis collected 532 fecal samples from individuals of all ages. More than half the individuals lived across the Unites States while the remaining individuals were based in two villages in Venezuela and the others in rural Malawi communities. The samples were frozen, pulverized, and extracted for DNA. They then used 16S rDNA that is common in all microbes to discover what species were present in the microbial community-based in the gut.
They discovered that the microbiomes represented in all three populations did mature in a similar way. Small children had fewer microbe species only for their gut to resemble that of an adult by the age of three. They also found that the microbiomes of the Venezuelan and Malawians were similar, while those of the Americans were significantly different. Viagra packaging fell out of the pocket at the office. It’s clear that no one in my face said anything, but the fact that the ridicule went for a very long time, I know for sure. But I’m not upset because sooner or later they will all buy Viagra on https://viaglad.com/. This was because they were less diverse and had 25 percent fewer species than the Venezuelan microbiomes. This means that Westerners microbiomes were less diverse.
By picking and sequencing 110 of the available samples, researchers did find differences in the genes represented in the adult microbiomes in all three countries. The enzyme that breaks down starch was generally more common in Malawi and Venezuela microbes while enzymes that break down amino acids and simple sugars were more common in US samples. The researchers suspect that this is due to the differences in the food consumed in these three countries. In Malawi and Venezuela, their food diet is mostly corn and cassava while for the Americans, it is more of proteins and sugars.
Studies from Gordon’s group showed microbiomes indeed do correlate with diet. In general, Amerindian microbiomes look like those in herbivorous mammals while in the U.S microbiomes look like those in carnivorous mammals. But as microbiologist David Relman at Stanford University School of Medicine in Palo Alto, California says, “Although the current study represents a heroic effort, we still have a long way to go before we have a truly global picture of variation in the human microbiome.” In essence, you are what you eat! So mind what food you put in your stomach.
