Refined Carbs Decrease Cognitive Performance, Study Shows
French scientists have linked refined carbohydrates to worse cognitive function, even when consumed by young, healthy adults. Complex, unrefined carbohydrates like whole grains are an essential piece of a well-rounded diet; industrialized, refined carbohydrates like white bread, on the other hand, which go through a process stripping them of nutritional properties like bran, starch, and fiber, aren't good for much more than a quick sugar hit, as opposed to a sustained energy boost. The introduction of refined carbs into the human diet is a very recent phenomenon, at least in the grand scheme of human history, and our brains may well be suffering for it.
