This is a new study that could push even more health experts to recommend e-cigarettes to smokers. Indeed, this new pilot study presented by the Dr. Christopher Stewart tells us that vapers have the same mix of intestinal bacteria as non-smokers.
SMOKING AFFECTS STRONGLY THE MICROBIOME!
Linternational team of researchers led by Newcastle University analyzed the bacteria of tobacco smokers, vapers and nonsmokers from samples taken in the digestive tract including the mouth and intestines.
Significant changes have been found in the intestinal bacteria of smokers, with an increase in the bacterium Prevotella which is linked to an increased risk of colon cancer and colitis. There was also a decrease in the presence of Bacteroides in smokers, a beneficial bacterium or a probiotic. A lower rate of Bacteroides has been associated with Crohn's disease and obesity.
And that's where the vaping gets its game! Indeed, the Dr. Christopher Stewart, Lead author of the study and specialist in cell medicine at Newcastle University also discovered that the intestinal flora of those who use electronic cigarettes was the same as that of nonsmokers.
In the in the review peerj where he reveals his results, Dr. Stewart explains: " Bacterial cells in our body are more numerous than our own human cells and our microbiome is more than our brain, but we are just beginning to understand how important it is for our health. »
If more investigation is needed, discovering that vaping is less damaging than smoking on our gut bacteria is a breakthrough that will push health experts a bit closer to recommending e-cigarettes to smokers.
This pilot study is the first to compare the microbiota among smokers and users of electronic cigarettes. Samples were taken from 10 electronic cigarette users, 10 tobacco smokers and 10 non-smoking controls. Faeces, mouth samples (oral) and saliva were subjected to targeted sequencing to identify the bacteria present. This revealed significant changes in the intestinal bacteria of faecal samples.
In samples from the mouth and saliva, which are sites directly exposed to smoke or steam, the researchers also found that the bacteria in smokers were different from those of non-smokers. However, as in the intestine, bacteria in the mouth and saliva samples were similar among e-cigarette users and non-smokers..
In his study, Dr. Stewart states, " This research is interesting because we see a huge increase in the number of people using electronic cigarettes and it is becoming increasingly important that we understand the effect on the human body. "
Dr. Stewart's team hopes that further research will be conducted as a follow-up to this pilot study to study a much larger group over a longer period. They also suggest that more in-depth studies on sex-specific microbiota profiles be conducted.
