The explanation is that IQ measures the cerebellum, and the declining nutrition and increasing brain damage forces people to rely more on the cerebellum, the statistical engine, instead of abstract thinking.
Hmmm, I could imagine microplastics, PFAS, artificial dies, excessive and unhealthy amounts of sugar would all have a deleterious effect on IQ. Perhaps even specifically pre frontal cortex, etc.
Though that goes against Europe hitting the decline earlier than the US which leads in sugars and unhealthy foods.
There is nothing wrong with sugar, people can't burn it, because the body needs lead to break it into pyruvate. Then you need arsenic to input that into the krebs cycle. The mitochondria need a wide assortment of metals (likely at least copper, arsenic, selenium, mercury, cadmium and possibly chromium) when you don't get those, your mitochondia begin to fail, and the tissues where they do turn into "fat tissue".
I suspect they don't do the research for real, they do some kind of simulation, and write it was in mice. They do know the metal changes the protein, but they incorrectly claim that the version without it works, but in reality the one with it does. They could'n make such an error if they actually did the research for real.
