The linkage between consumption of these chemicals, and their exact nature of harm, is not well established- it's not "fairly conclusive" at all.

"be careful in doing your review." Says the lazy poster who just made a bunch of claims himself and didn't cite anything!
The burden of proof is on the one making unsupported claims, not on the one questioning the unsupported claims. (It's tedious to post supporting studies on every post, so there's nothing nefarious about claims being initially unsupported.) I do agree that the "be careful..." comment is perhaps open to being interpreted as snarky, though it's always hard to infer the intent in a forum such as this.
I'm just working to save time by making people who make outrageous claims do the work to produce supporting evidence. I'm really tired of people (especially non-scientists) citing articles they haven't read or aren't qualified to evaluate.

#163My belief is that the primary cause is environmental chemicals, specifically Phthalates and BPA (and related chemicals). The science on this is fairly conclusive. We can show that these chemicals bind to estrogen receptors, that they're present in everyone's body, and that if you're acutely exposed to a higher dose, your testosterone goes down. In my opinion, these chemicals are having social and cultural effects bey…
Alright, so what should we do? Should we daily take DHEA/GABA/Zinc etc. to compensate effect of these chemicals? Eat only food we grow/kill ourselves? Move to mountains shielded from airborne pollution?

>The burden of proof is on the one making unsupported claims, not on the one questioning the unsupported claims. When public health issues are concerned, the burden of proof is on the ones saying exposure does not present any risks worth worrying about. The FDA doesn't usually come in with the approach that we should just try everything out and see how it goes.

That sounds like an excellent reason to throw a lot of money at doing epidemiological studies then, doesn't it? I must say I'm very tired of naysayers with no positive proposals of their own who invoke the scientific method as a way of waving away problematics rather than engaging with their evaluation or mitigation.

Countries with low obesity levels show the same trend [1]; just look at e.g. Denmark (18.2%) [2]. [1] https://www.ncbi.nlm.nih.gov/pubmed/10655308 [2] (PDF) http://www.euro.who.int/__data/assets/pdf_file/0006/243294/D...
This suggests an environmental factor or a different dietary one. Probably not BPA or such, there would be more of a difference between western countries. Plus Asia would show it too. (Heck, they make and use a lot of these plastics.) Not atmospheric pollution either apparently (see French result). Electromagnetic wave pollution perhaps?
Why do you say that? Most western countries use plastic and receipts (thermal paper), which are the main sources.
And BPA isn't the only xenoestrogen. PCBs, dioxins, and many agricultural biocides are too.

I feel like something happened in the early 70s that just made progress slow way down. I keep seeing bad trends start in the 1970s - like stagnant wage growth (1971), increased inequality (1971) etc...
ARPANET was created in 1969. Distract all your geniuses with cat pictures and flame wars, and doom is sure to follow.

#170Turns out modernity is an extremely unhealthy environment for humans, especially men. Despite the narratives being thrown at you, we live in an incredibly "feminized" society where social stigma/violence/shaming are more powerful for the average person than plain old physical violence.
