"We can keep running on the macronutrient treadmill, like we've been doing for 50 years, or we can find molecular evidence that jives with genetics."

Yes, let's ignore 50+ years of established science that is parsimonious with everything we know about the molecular biology of insulin resistance, and dump it in favor of a fringe theory, based on a single paper about a mouse study, where there's not even a plausible explanatory mechanism.

Folks, stop downvoting simply because someone provides a link. The parent is spouting pseudo-scientific nonsense.

There are literally hundreds of papers on BPA and its links with diabetes. The only difference now is that we have the molecular culprit behind the trend.

"There are literally hundreds of papers on BPA and its links with diabetes."

There are literally not. The review you've linked to cites a handful of papers involving minor effects observed in mouse studies.

Moreover, the paper you originally cited proves nothing even approximating a mechanism. I'm not suggesting anything about the safety of BPA, but it's utter nonsense to claim that it is a more plausible explanation for the diabetes epidemic than sugar consumption.

A few mouse studies do not change 50+ years of established science on the relationship between sugar and diabetes.

But is it really?

Elevated blood glucose, as in Type 2 Diabetes, has LONG been known to be primarily driven by excessive production of glucose by the liver due to liver insulin resistance. In fact, the way that the drug metformin improves diabetes is by shutting that pathway down.

http://diabetes.diabetesjournals.org/content/50/8/1807.short

Thats not dietary, thats the hormone insulin being ignored by the liver. This is further complicated by the fact that peripheral tissues, like muscle, are themselves insulin resistant.

The TCF7L2 pathway has been shown to be down-regulated in all of these tissues in diabetics.

Re:Tiny Plastic Is Everywhere by timr on Monday August 20, 2018 @05:30PM (#17804164)
TCF7L2 is a transcription factor. It is involved in many pathways in human biology, of which diabetes is one.

Observing that it is downregulated in diabetics provides no evidence for or against any theories concerning BPA.

Re:Tiny Plastic Is Everywhere by subcosmos on Monday August 20, 2018 @05:47PM (#17804304)
It's also the most statistically significant gene, in the whole dang genome, associated with Type 2 Diabetes.

And out of a compound library of 20k chemicals, BPA had the top effect on it.

Seems significant to me

Also worth noting that BPA has been shown to specifically effect the occupancy of TCF7L2 at transcription factor binding sites in Chip-Seq experiments.

Lastly, before calling someone else's claims psuedoscientific, you may want to do some homework and check your previous biases. We could certainly use someone with your skills to help model BPAs interaction with the Androgen receptor. Might just save millions of lives....

No, there literally are hundreds. Look at the graph in pubmed.

Forgive me, but I don't have time for this.

It’s interesting to notice that what we have here is one industry being villified, and then possibly passing the buck, only to point at another industry as possibly to blame.

It’s pretty interesting to think about how easy it is to muddy the waters like this. Something starts off as a direct medical concern, but then sprals into a secondary contamination problem. Both are bad. Plastics are bad for a variety of reasons, and sugars definitely contribute to obesity.

But, horomonal factors really cannot be shrugged at. There’s some serious distortion affecting people for the past 20 or more years, and it’s nothing normal. Is it birth control pills being dumped down the drain, and recirculating into the drinking water? Is it ibuprofen messing with people who have over dosed on their analgesic NSAIDs?

One thing’s for sure modern civilization has inteoduced many complications, all simultaneously, and that is likely the biggest mistake of all.

Also, I’m not sure you’ve used the word “parsimonious” correctly? Are you trying to say they’ve been “very careful” or “strict”? I think it’d be more appropriate to replace it with “well aligned” or “concomitant” if a vocabulary word should be preferred.
