Smoking makes you fat, especially passive smoking.

Increases insulin resistance. This was revealed in a study published in the American journal of physiology, endocrinology and metabolism. "Those who live with a smoker, especially the child has a higher risk of cardiovascular and metabolic disorder"

SMOKING, especially the passive makes you fat: to disprove the belief that smoking cigarettes helps to stay thin is a study from Brigham Young University in Salt Lake City, published in the American journal of physiology, endocrinology and metabolism. "Those who live with a smoker, especially if the child has a higher risk of cardiovascular and metabolic problems," says Benjamin Bikman, author of the research. Only half of the US population is exposed at least once a day to secondhand smoke and about 20% of children live with someone who smokes in the house. Each day, moreover, almost 4 thousand adults smoke their first cigarette and 1,000 become regular smokers.

Increases resistance to insulin. In the study the researchers wanted to analyze, in mice, the link between smoking and metabolic functions, in particular the mechanism by which smokers become resistant to insulin. Exposing animals to tobacco smoke, as well as have gained weight: smoke it pushes some small lipid molecules, ceramides, to alter the mitochondria of cells, resulting in the destruction of normal cellular functions and inhibiting their ability to respond to 'insulin. "Our research - he added - show that between the responses to passive smoking in our body is the alteration of insulin sensitivity. Once this continues to increase, you get fat." The key is to reverse the effects of smoking, inhibiting ceramide. Researchers have seen that treating mice with a substance that blocks the mioriocine, took no weight or had metabolic problems. However, if, in addition to passive smoking, the rodents were fed a diet high in sugars, metabolic damage could not be fixed. Now researchers are looking for an inhibitor of ceramide that is safe for men, in order to protect those who are exposed to secondhand smoke.

Quitting smoking does not make you fat. The results of this study could help overcome the fears of those who think that leaving the blonde could get fat. But by previous research, the University of Otago, revealed that this fear is unfounded. The researchers, examining a sample of 1,000 people, they found that those who were inclined to put on weight, he did it anyway, over the years, even if he was smoking again.

The risks of passive smoking. 25% of the Italian population is exposed to the dangers of passive smoking and 8 out of 10 people do not know that causes cancer of the lung. According to a survey by the Italian Association of Medical Oncology (AIOM), 71% regularly smoking indoors, while 43% give up cigarettes does not reduce the risk of developing the disease. The level of knowledge about risk factors is poor, in fact, almost half of people (48%) think that this cancer can not be prevented. Widespread ignorance of concern, given that 49% say they smoke in the presence of children, and only 45% would change his lifestyle to prevent cancer.

Children at risk. A phenomenon that can produce risks of smoking, especially for the little ones. According to research Bambino Gesù Hospital in Rome, a 5 children among those who have access to clinics for respiratory problems, coughing or bronchospasm, problems associated with passive smoking. According to other research at least one other child from the second year of life is regularly exposed to secondhand smoke. While the ISTAT data show that 49% of children under 5 has at least one parent who smokes, while a newborn is the mother of 5-smoker. In Italy, people who smoke are 11.3 million, 22 percent of the population of 6.2 million people, 25.4 percent, and 5.1 million women, or 18.9 percent. Ex-smokers were 6.6 million, 4.6 million men and 2 million women.
