plasticizers

https://www.merkur.de/leben/gesundheit/us-studie-weichmacher-wirken-sich-intelligenz-kindern-zr-4526690.html

Plasticizer in plastic makes stupid
In PVC, room sprays, packaging or cosmetics - plasticizers are everywhere. For the first time, US researchers have proven that these chemical substances damage the brain.

According to a US study, frequent contact with plasticizers during pregnancy affects the intelligence of children.

Schoolchildren in the USA whose mothers had high levels of phthalates in their bodies had an intelligence quotient (IQ) that was on average six points lower than that of children whose mothers were only slightly exposed to the plasticizers used mainly in plastic products and cosmetics, as the scientists from the Mailman School of Public Health at Columbia University in New York wrote in their study published on Wednesday (local time).

Researchers call for plasticizer ban
The researchers around the epidemiologist Pam Factor-Litvak strongly advised pregnant women to ban softeners from their lives if possible.

"Pregnant women throughout the USA are exposed to phthalates almost daily," the scientists warned. While there were restrictions on plasticizers in children's toys, there were no legal regulations on maximum levels during pregnancy. This is one of the most important phases of development for the human brain. Plasticizers are also frequently found in PVC, air fresheners, packaging for microwave meals and many recycled plastic products.

The study is the first to demonstrate a link between prenatal phthalate exposure and IQ levels in school children aged seven years. According to the study, the children of more severely exposed mothers, who had the highest concentrations of DnBP (di-n-butyl phthalate) and DiBP (diisobutyl phthalate) in their bodies, had IQ values 6.6 and 7.6 points lower, respectively, than children in the comparison group with the lowest previous exposure. ...

You can drink from sun baked water bottles and eat from microwaves plastic plates and chug flouride water every day of your life so long as you produce physical activity equal to pre-industrial eras. If you do this your body is going to reach it's final form. All you need is physical activity. 100% of modernity can be undone by increasing physical activity, just keep increasing the activity eventually it is all fixed.

Obviously the conclusion that since event Y followed event X, event Y must have been caused by event X is a logical fallacy. But pointing out the reasons of the cause of something and listing x along with other factors is not one. Is it possible that it scares you that there is a possibility, albeit not a strong one, but one nonetheless one, that the increase in inmigration over the last few years in scandinavian countries has had an impact on the decreasing iq scores in the last few years?

Is it possible that you choose subjectivity over objectivity in matters that go against your own personal belief?

This is not to undermine you since this is a perfectly normal human behaviour but putting up a front of objectivity and reason when its not always entirely the case is misleading.

You talk like a woman and faggots should be thrown from buildings. Hunter gatherer diets still exist today, but the physical output is not anywhere close. Your study is pants on head garbage and I dont even need to read it. Hormone regulation derived from physical effort is SIGNIFICANTLY more important than a meal. You also clench your jaw harder while exercising than you do while eating. You have no clue, but diet is less than 1% of the reason your jaw is shaped the way it is. I know you have a low IQ and can't wrap your head around the levels of impact things have. You probably just see 4 options and think they are evenly distributed.

Sexual revolution + welfare state + women's education means that intelligence that usually manifests in a modern society as wealth isn't being selected for anymore in favour of attractiveness. Why marry at a young age to a rich man and remain exclusive to him when you can choose to fuck the most attractive men instead and still have your basic needs met? And if you are a smart woman with education, a child is only a hurdle for success in the other areas of your life.

Because around here child mortality dropped dramatically in the early 1900's and more so after WWII when antibiotics became easily available. By 1960's child mortality was no longer a problem.
So if the hypothesis that high child mortality benefits high IQ families, the effect should have been seen earlier. Since the premise of this entire thread is that the IQ drop is a rather recent trend, the hypothesis must be disqualified.

>Variation in the masticatory behavior of hunter-gatherer and agricultural populations is hypothesized to be one of the major forces affecting the form of the human mandible. However, this has yet to be analyzed at a global level. Here, the relationship between global mandibular shape variation and subsistence economy is tested, while controlling for the potentially confounding effects of shared population history, geography, and climate. The results demonstrate that the mandible, in contrast to the cranium, significantly reflects subsistence strategy rather than neutral genetic patterns, with hunter-gatherers having consistently longer and narrower mandibles than agriculturalists. These results support notions that a decrease in masticatory stress among agriculturalists causes the mandible to grow and develop differently. This developmental argument also explains why there is often a mismatch between the size of the lower face and the dentition, which, in turn, leads to increased prevalence of dental crowding and malocclusions in modern postindustrial populations. Therefore, these results have important implications for our understanding of human masticatory adaptation.
