Some nutritionists abroad warn that overeating can impair brain function, making it sluggish.
Research has found that a substance called fibroblast growth factor increases by tens of thousands of times in the brain after a meal compared to before, and it is believed that this factor is one of the causes of cerebral arteriosclerosis. After people eat, the body regulates this growth factor, bringing it back from a high state to a normal level. However, if one eats to excess over a long period, this factor will accumulate in the brain, promoting the formation of cerebral arteriosclerosis, which is closely related to senile dementia. Therefore, experts recommend that meals should not be too full, and it is advisable to eat until 7-8 full.
