Overeating: Not a brain-smart choice

The newest issue of Physiology & Behavior includes a compelling review of how diet impacts the central nervous system and brain function. According to the authors, “acute intake of hypercaloric diets impairs cognition, even in healthy subjects.” In other words, a habit of overeating impairs brain function, even if it does not result in obesity. The study also confirms a link between dietary-induced insulin resistance and cognitive decline, and correlations between fatty diets and diminished ability to control impulses. We’ve all known that overeating can cause obesity, diabetes, and heart disease; now we are learning that it can diminish brain function. Sounds like the ‘super-size-me’ order equates to a ‘stupid-me’ future.
