The Problem With PFASs Found in Carpets, Coats, Cookware
Did you know that chemicals used to make non-stick pans, stain-resistant carpets, and some food packaging may contribute to the high level of obesity? Scientists proved that these elements disrupt the body’s ability to burn calories. Researchers have examined the effects of compounds called Perfluoroalkyl Substances (PFASs), linking them to cancer, high cholesterol and immune problems.
An experiment has been held by top nutritionists which included over 200 obese people dieting for 6 months. As expected, the participants lost weight – on average 6.4kg – but then regained nearly half of that in the following 18 months. What the scientists found that was extremely important. Those, who gained the most weight after dieting, had also the highest blood levels of PFAS chemicals, and the effects were more pronounced in female participants.
According to the official report, women in the study with the highest PFAS levels re-gained around 2kg more than those with the lowest ones. The scientists went on to show that those with high levels of PFAS in their blood also tend to burn calories more slowly than the rest, as it was measured by their resting metabolic rate.
These chemicals may be the sole lead to more rapid weight gain after dieting was the final outcome. Also, it was very hard to avoid exposure to PFASs, but people should try to, as this is an increasing public health issue.
Figures stated by the European Food Safety Authority suggest that exposure to certain types of PFASs in Europe are way below the tolerable daily intake (TDI), the amount of a chemical deemed to be safe for consumption over a human lifetime. For the Perfluorooctane Sulfonate, for example, the typical adult consumed less than 3.5% of the TDI.
A professor of toxicology at Imperial College, London, said that while the findings were intriguing, it was impossible to know for certain whether Perfluoroalkyl compounds were responsible for weight gain. There is the potential that at least some of the findings are due to chance. The results can serve as a good basis for further and more focused investigations into a possible link between exposure to PFASs and weight fluctuation.
