❝ Being overweight can raise your blood pressure, cholesterol and risk for developing diabetes. It could be bad for your brain, too.
A diet high in saturated fats and sugars, the so-called Western diet, actually affects the parts of the brain that are important to memory and make people more likely to crave the unhealthful food, says psychologist Terry Davidson…
❝ He didn’t start out studying what people ate. Instead, he was interested in learning more about the hippocampus, a part of the brain that’s heavily involved in memory…He did that by studying rats that had very specific types of hippocampal damage and seeing what happened to them.
In the process, Davidson noticed something strange. The rats with the hippocampal damage would go to pick up food more often than the other rats, but they would eat a little bit, then drop it.
Davidson realized these rats didn’t know they were full. He says something similar may happen in human brains when people eat a diet high in fat and sugar. Davidson says there’s a vicious cycle of bad diets and brain changes. He points to a 2015 study…that found obese children performed more poorly on memory tasks that test the hippocampus compared with kids who weren’t overweight.
❝ He says if our brain system is impaired by that kind of diet, “that makes it more difficult for us to stop eating that diet. … I think the evidence is fairly substantial that you have an effect of these diets and obesity on brain function and cognitive function.”…
❝ Davidson is…moving forward by studying how to break the vicious cycle of a Western diet, obesity and brain changes. But he says the underlying idea that obesity affects the brain is clear.
“It’s surprising to me that people would question that obesity would have a negative effect on the brain, because it has a negative effect on so many other bodily systems,” he says, adding, why would “the brain would be spared?”
Another smartass scientist who lets sound logic and data get in the way of profits from corporations producing and selling crap food. Will they never learn?
RTFA for a range of studies that move from correlation to causation.
