A group of scientists from Cornell University have discovered a genetic mutation that distinguishes hereditary vegetarians from people in the diet of the ancestors which were traditionally present meat. This mutation is most common in areas with a developed culture of vegetarianism based on religion or tradition, experts say.
Scientists found box, found in the genome of vegetarians, is an additional 22 “letters” in a gene called FADS2. They help the body to more effectively synthesize some fatty acids that are ready for people who eat meat, get out of it, reports australianetworknews.com.
In favor of the assumption that the difference at the genetic level due to the traditions associated with consumption of meat or a waiver of, the fact that residents of the Indian city of Pune, where people for many generations adhere to Hinduism, the corresponding mutation is found in 68 percent of cases, while among inhabitants of the USA — only 18 percent. Hinduism implies the renunciation of eating meat, while in the U.S. Dating back centuries, widespread tradition of vegetarianism does not exist.
Scientists have also found that “the mutation of vegetarianism” is found the majority of people in South Asia and Africa, but rarely in those living in Europe. Researchers claim that they managed to prove the importance of the distribution of mutations among hereditary vegetarians from an evolutionary point of view.
The experts presented their study in the journal Molecular Biology and Evolution.
If the relationship between the detected mutation and a vegetarian diet is proved, it will not be the first proven case of the influence of diet on genes. One of the most famous examples is the ability to digest milk in adulthood — a time when men, in the majority, it could not, but the domestication of livestock change this situation, provoking the emergence and spread of genetic mutations that allow you to include milk in the diet.Related posts:
