BriocheDoree, I'm not quite sure what the parents are supposed to have done to rewire the brain into a completely different pattern. Do they think parents are amazing brain surgeons able to carry out microscoping rewiring of circuits linking social areas to the rest??! Quite mad... !
The US approach re feeding might actually have a small amount of sense to it for some of us, and the scientists are starting to understand why. The brain wiring is done by a microscopic "mechanics team" in the brain who are working off some sort of blueprint for building a brain. Except that somehow they change their mind about what they're building.
Try this as an example. I'm sorry that it's about cars, but it sort of works for me:
Instead of building a brain that's more like a "family hatchback" car (with room for lots of people and the weekly shopping and able to handle ordinary roads), the brain-building team decide to build a Formula One racing car with room for only one person and no way to get over road bumps or fit the shopping in. We don't know why, because we don't know where they're getting the blueprint for it from. But you end up with people who only have 'room' in their brain to think about one person at a time, can't handle life's ups and downs very easily, and need careful handling...but whose brains can accelerate at incredible speeds IF you can put it in gear.
Somehow, what some of us eat changes at least the fuel mixture so it's easier for us to keep running rather than grinding to a halt.
