Coffee, Eggs and White Rice Linked To Higher Levels of PFAS in Human Body (theguardian.com) 68

Posted by msmash from the new-scare-unlocked dept.
New research aimed at identifying foods that contain higher levels of PFAS found people who eat more white rice, coffee, eggs and seafood typically showed more of the toxic chemicals in their plasma and breast milk. The Guardian adds: The study checked samples from 3,000 pregnant mothers, and is among the first research to suggest coffee and white rice may be contaminated at higher rates than other foods. It also identified an association between red meat consumption and levels of PFOS, one of the most common and dangerous PFAS compounds. The authors said the findings highlight the chemicals' ubiquity and the many ways they can end up in the food supply.

    At which point does it get contaminated? Nobody knows. Article doesn't say, besides just "beans, water for brewing, or soil", and that's still vague. I would suspect that grinding your own beans at home might be a bit safer than, say, instant coffee, but that's a wild guess eh?

      • Rice in an instant heat package?

        • An interesting question, also was thinking if further there was a difference between that and a rice cooker which is far more common in asian countries but some of those even have a nonstick coating on the bowl as well.

          • I've never understood the point of a rice cooker but this may have to do with the fact that I've only ever cooked a couple cups of rice at a time. It's incredibly easy to just bring liquid to a boil in a sauce pan, pour in rice, cover, and reduce heat to simmer and set a timer for 20 minutes. 2:1 liquid to rice ratio and it comes out more or less perfect every time.

            • I somehow burn it every time like that. A rice cooker often has just a single button. Put water and rice in the bowl, you'll learn your favorite ratio with your machine, press the button, wait. Couldn't be easier. Super consistent.

              • Youâ(TM)re cooking it too hot. Turn heat down to lowest setting when youâ(TM)re cooking it. Once itâ(TM)s at a boil it doesnâ(TM)t take much heat to maintain. I used to use a rice cooker for same reason. Then I learned to cook it on the stove top and now thatâ(TM)s what I do all the time. And it doesnâ(TM)t stick or burn.

                I've had two different microwave rice cookers, and they give fast, perfect results every time. They're much lighter than electric rice cookers and take up less space. Sadly, they're also made of 100% plastic... :-{

              For white rice, I don't see the point either. I don't even use simmer as on an electric stove you can just turn the burner off and it cooks on the residual heat.

    in the actual foods? Or just in the people who, on surveys, said they ate such foods?

    It strikes me that these are very broad, overlapping categories. For example, lots of people both drink coffee and eat eggs. Did they observe a difference in levels between people who drank coffee but didn't eat eggs, or vice versa? I'll bet many of these people also ate bread, and candy, and sausage, and frozen pizzas, and who knows what else.

    Nutrition science is hard, and lots of studies cut corners and draw conclusions that aren't necessarily supported by the controls, or lack of controls, in the study.

      • All your theories have potential merit. Proving it, or even concluding that any one of the sources of PFAs is "likely" is an entirely different matter. This study certainly didn't prove a link.

      • The other possibility is people who mostly get their coffee from places like Starbucks, Dunkin Donuts and such in paper cups; I'm sure those cups have a PTFE coating on them.

      Yes. And by that I mean all of the above and more. Yes there are studies on self reporting of eggs. Yes there are actual studies that show eggs are an easy way of getting PFAS into the body. Yes there are studies on eggs showing they are contaminated with PFAS during farming. In fact there's also guidance in some parts of the world not to actually farm chickens yourself because your area leads to eggs being laid with PFAS levels determined not fit for consumption.

      • Everything you said might indeed be true, but it doesn't help THIS study prove what it purports to prove. THIS study took surveys of pregnant women to see what they ate and drank, and also measured the levels of PFAs in their placentas and blood. There are too many overlapping potential sources in the various foods the women ate, to be able to control for any one of them. You might be very certain in your convictions, but that doesn't make THIS study a good source of information.

      white rice is just what's left when you remove all nutrients from any rice except the carbohidrates in the grain and say merry godbye to all vitamins, minerals, essential fatty acids, antioxidants and fiber that were in the bran. genetics vary, but the difference is mostly in the processing, and since brown rice processing only removes the husk, it retains most of the bran so is indeed much, much better as a nutrient.

    Maybe the eggs are related to the non-stick frying pans. I try not to use non-stick, but for eggs it's hard not to. I should try frying them in a stainless steel pan and see how it goes. For coffee it could be that people order them in paper cups that have a plastic coating to make them waterproof, or drink them out of cups with plastic lids, or brew them with single-serve pods that are make out of plastic. It's hard to escape this stuff.

        Exactly this. It doesn't take long for a cast iron pan to become nonstick as long as you never use soap, cleaners or other solvents on it. Just rinse it with water and wipe it, or let some water sit in it for some minutes if anything gets stuck on it, scrape it with a plastic scraper and rinse and wipe it dry. Keep using it, keep oiling it and it will be awesome for eggs in no time. And avoid cooking acidic foods in it (tomatoes etc) which can strip the oily coating.

    • Maybe the eggs are related to the non-stick frying pans.

      Rice is a similar case. I've tried to find a rice cooker that doesn't have non-stick coating (read: PFAS) and as far as I can tell, there are none.
