Scientists have discovered in the intestines of humans eating greasy Western food, special microbes that contribute to the absorption of fat in the digestion of food and accelerate the development of obesity, according to a paper published in the journal Cell Host & Microbe.
“These bacteria proved to be one of the key links in the chain of events leading to that intestines more efficiently absorb fats. Few who have studied the microflora of the small intestine, and we were the first to show that these bacteria control the digestion and absorption of fats, and plays a huge role in the development of obesity and heart disease,” said Eugene Chang (Eugene Chang) from the University of Chicago (USA).
In recent years, scientists have uncovered a variety of negative features of the Western diet, which is characterized by a large number of calories and fatty foods. For example, a year ago, scientists discovered that fatty foods promotes the development of Alzheimer’s disease and changes the brain so that the person starts to eat more and two years ago they found that fast food makes a person forget that he already ate.
On the other hand, the reason why the Western diet causes people to gain weight quickly and not lose it even after the rejection of fast food and other “gifts of civilization” remained a mystery to scientists.
Chang and his colleagues found, why it happened, trying to understand why mice with purified intestinal microflora is almost not gained weight, as did their relatives, sat in the normal or typical “Western” diet with lots of fat and calories.
