Scientists have finally solved the weight gain after quitting smoking
Smoking - pyrolytic inhalation (inhalation of smoke) of drugs, mainly of plant origin, smoldering in a stream of inhaled air, in order to saturate the body with the active substances contained in them by sublimation and subsequent absorption in the lungs and respiratory tract. As a rule, it is used for the use of smoking mixtures that have narcotic properties ( tobacco, hashish, marijuana, opium, crack, etc. ) due to the rapid entry of blood saturated with psychoactive substances into the brain. aromatic substances used in religious rituals, in aromatherapy and for the aromatization of air.
For countries and territories of the world that provide relevant information in WHO, the prevalence of tobacco smoking among adults varies from 4% in Libya to 54% in Nauru. The top ten countries in which tobacco smoking is most widespread include, in addition to Nauru, Guinea, Namibia, Kenya, Bosnia and Herzegovina, Mongolia, Yemen, Sao Tome and Principe, Turkey, Romania. Russia in this series of 153 countries ranks 33rd (37% of smokers among adults). However, despite the fact that, for example, the United States ranks 98th in this row (24%), the average per capita consumption of cigarettes here is higher than in many countries of the world with a higher smoking prevalence among adults. If the United States consumes an average of about 6 cigarettes per capita (that is, including children and all non-smokers), then in Russia it is less than 5. And the highest level of per capita cigarette consumption in Greece is almost 12 pieces per person per day. According to the latest WHO, the country with the lowest percentage of smokers in the world is Turkmenistan.
Scientists from the University of Michigan Institute of Life Sciences conducted a study in which they found that the link between smoking cessation and weight gain may explain the discovery of a new type of fat cell, beige fat .
During a scientific experiment, experts investigated beige fat and found out that it contains CHRNA2, a protein that is encoded by the gene of the same name, writes the Independent. In white fat, a similar encoded protein genome was not detected, the scientists noted.
CHRNA2 is also associated with the level of nicotine addiction in the brain. Thus, this relationship can explain the appearance of excess weight after a complete cessation of smoking, which is quite difficult to get rid of for a long time.
"We will continue to explore beige fat and hope that this will help us find answers to those questions that were previously unexplainable," concluded the author, Professor Joon Wu.
