Do not blame the dough or extra slice of pie. At least not entirely.
If you gained weight, the cause may be, in part, daily household dust.
Researchers at Duke University point out that chemicals from several common household products stick to dust particles. Some of these chemicals, the Endocrine Society writes about Duke's study, "promote the development of fat cells in a cellular model," expanding previous research that has shown that such substances trigger triglycerides, a type of fat in the blood.
"Many observational studies," the society writes, "found a link between exposure to endocrine disrupting chemicals and weight gain in humans."
Duke researchers collected about 200 dust samples from homes in North Carolina and extracted the chemicals from the dust. The study aimed to determine if domestic dust contributes to childhood obesity. The risk appears to be relatively low, although the research found that a number of fat cell development chemicals – found in cleaners and laundry detergents, among other household items – were "significantly high in the children". who were overweight or obese.
"We found that two-thirds of the dust extracts were able to promote the development of fat cells and half promote the proliferation of precursor fat cells at 100 micrograms, or about 1,000 times less than children consume daily," postdoctoral research Duke University. Christopher Kassotis said in a press release.
The Environmental Protection Agency estimates that children typically consume between 60 and 100 milligrams of dust every day.
