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.

Bill Gates' contrails are capable of adding these chemicals to the drinking water.
Yes, your tap water needs to be filtered.
Great. Something else in the kitchen to be worried about.
Next time I get water to swallow my med pills,
I’ll think about actor Dustin Hoffman, as he sat in the dentist’s chair, with the Dentist (Lawence Olivier) repeatedly asking him (the patient) “Is It Safe?”
We don’t drink any water that has not passed through our Berkey water filter.
My household drinks water exclusively from our well. When we travel, we take our own water. I weighed 98 pounds when we married 45+ years ago. I weight 115 now and that’s after gaining up to 130 with my second child (40 years ago).
Don’t drink the city water and vet your bottled water carefully.
Ok, what are PFAS? I didn’t see the definition of the acronym.
[sounds like a crisis!!!]
Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS)
What Are PFAS?
Per- and polyfluoroalkyl substances (PFAS) are a large, complex group of synthetic chemicals that have been used in consumer products around the world since about the 1950s. They are ingredients in various everyday products. For example, PFAS are used to keep food from sticking to packaging or cookware, make clothes and carpets resistant to stains, and create firefighting foam that is more effective.

I’m a bit torn, but this is a strictly correlative study.
The reason that I’m torn is because I’ve used Philippe Grandjean as a reference in one of my books. He’s done some very good research exposing the toxicity of fluoride.
I’m not impressed with this study. It’s a shame it didn’t include any insight into the mechanism to adverse health effect (thought to be an endocrine disruptor).
I don’t dispute a negative health impact from exposure to PFAS (in fact, I agree wholeheartedly) but this study might as well have concluded that lack of sunlight correlates to obesity.
“The purpose of this study was to test the hypothesis that perfluorinated alkylate substance (PFAS) exposures are associated with body weight increases in a dietary intervention study.”
It establishes nothing of the sort. The time to establish the mechanism was during the study via testing; it’s shameful, as are the conditions for the study,
“The adults first underwent a diet of 800 kcal per day for 8 weeks”
Read that again. Yeah.
Additionally, search the paper for the term “PFAS mixture”; it appears that the study participants ingested PFAS.
Again, yeah. /s “Human guinea pigs.”
The effects of this ‘study’ may well be quite interesting...
bkmk
“Water filters are capable of removing these chemicals.”
Water molecule size: 2.75 angstroms.
Covalently bonded fluorine - e.g., PFAS - molecule size: 0.72 angstroms.
I don’t think so, at least certainly not in the consumer sense. Some claim high filtration rates, but it’s physically impossible to reach some of the advertised rates of reduction (e.g., ‘93%’). Fluoride easily passes the blood-brain barrier; so do most of the >4000 other chemicals of similar structure.
Anyone interested in the latest research should note this:

One point: If we’re to eradicate a future threat - banning PFAS etc. - then it must include fluoride in water.
By the way, the feds regulate the amount of fluoride added to bottled water. Yeah, you read that correctly, and the bottlers are not required to list it on the label.
The results demonstrate that ‘purified’ bottled waters can’t eliminate the fluoride...or that it’s added post-filtration.

(let the games begin)
Teflon and fire-retardant-type chemicals.
One has to test each method to filter water to see if it removes teflon residues. The statement in the first post is useless. People would have been better off not reading it.
“I don’t think so, at least certainly not in the consumer sense. “
I agree with that.
In my case, I really don’t drink any water to speak of, not even the local Columbia River fed city water, whether filtered at consumer endpoint or not. I drink only Diet Coke, so if a chemical is in Diet Coke, I get it, otherwise not. So it would depend on where the water in the Diet Coke comes from.
It’s probably one of the best filtered waters.
I think one can have a good home system combining many filters, like carbon, distillation, ozone.
Many filters can attract molecules, meaning pore size can be irrelevant.
PFAS molecules are much larger than just fluorine would be.
One experience I had drinking coke was drinking low mineral water after drinking coke reduces the body’s potassium. I think phosphoric acid reduces calcium in the intestine, so one should eat some things to make it normal before drinking low mineral water.

Then the probability that you get PFAS by just adding HF in water is extremely small and can be approximated by zero.
Many types of PFAS are probably not good for our health, while some are more or less harmless in concentrations that are common.
In 2018, the OECD/UNEP Global PFC Group prepared a new list of PFASs that may have been on the global market. In total, a set of substances with over 4730 CAS numbers have been identified, including substances that contain such fully fluorinated carbon moieties, but do not meet the PFAS definition in Buck et al. (2011) due to a lack of a –CF3 group in the molecular structures. In addition, recent advancement of non-target screening analytical techniques using high-resolution mass spectrometry has enabled identification of many unknown substances in different environmental and product samples.
