A researcher has led a study that confirms a direct link between certain chemicals in drinking water and human obesity—specifically that increased PFAS content in blood promotes weight gain and makes it harder to keep a lower body weight after weight loss.
"We've previously shown that children with increased PFAS concentrations tend to gain weight and develop higher levels of cholesterol in the blood," said Grandjean, a professor of environmental medicine at the University of Southern Denmark, who has researched the human health impacts of PFAS in multiple countries and populations, including children, for decades. "We now focused on adults who participated in an experimental study of five different diets in regard to weight gain. Our results add to the concern that environmental pollution may be affecting our metabolism, so that we tend to gain weight."
For the recent study, the researchers analyzed PFAS chemicals in 381 blood samples that were already part of a randomized European Commission clinical trial in Europe focused on weight loss planning for obese adults. No matter the diet to which these participants were assigned, they gained weight if they had elevated PFAS exposures.
One particular chemical, PFOA, which is commonly found in contaminated drinking water, demonstrated—more so than other PFAS pollutants—ties to obesity. Furthermore, those participants in the European study with the most PFOA in their blood were found, after a one-year follow-up, to have gained about 10 pounds more than those with low levels.
"Our study adds new evidence that being overweight isn't just about a lack of physical activity and unhealthy eating habits—PFAS are increasingly suspected to be a contributing factor," said Grandjean.

I never asserted as much. HF was for reference and the comment on bottled water a segue re discussion of water filtration in general because, imho, anyone concerned about PFAS should share concern about HF.
However, if HF is present in bottled water, so are PFAS, as demonstrated by testing:
Some Bottled Water Brands Have Concerning PFAS Levels, Massachusetts Regulator Warns
If PFAS are present in bottled water following 'purification' (filtered tap water), then they are also present in any post filtration result of household water filters. Ironically, the linked test results and brands list no longer exist (even in archives). Go figure. /s
Note: There have been over 4000 PFAS/PFOS produced/used since the 1940s and, as the so-called 'study' demonstrates (somewhat uselessly), they do affect human health.
A general search will reveal that there are many papers/articles discussing filtration strategies for public water systems (as I linked), including strategies to break the carbon bonds to break down the substances; none of it is cheap and neither fully effective (yet). Due to the molecular weight of PFAS, they follow water columns and may descend into aquifers. To meet the marketing strategies of the manufacturers, we have poisoned ourselves. These substances should be evaluated for serious consideration of removal from use. Globally.
yes
;-)
That might explain why there were so few overweight people in the 50’s... or maybe that’s just my personal experience from the time.
Have you looked into the effects of ozone or reverse osmosis on water with teflon residues? I think ozone disintegrates plastic.
I’m on a well, so it’s not a concern for me.
But there are MANY reasons why I wrote an entire book on drinking water...and I cover nearly all of them.
