As far as fad diets go, the low-carbohydrate train has enjoyed a prolonged ride when compared to its more trendy counterparts. Some dieters shun carbs because their bodies respond by shedding pounds, but new research shows they could also be sacrificing some very important brain power.
The brain converts carbohydrates to glucose for proper functionality, and severely restricting carb intake can limit our ability to remember. Nineteen women were put on either a very low-carb diet or the low-calorie diet recommended by the American Dietetic Association, and after just one week the low-carb dieters performed worse on memory-based tasks than the women following the ADA diet.
While low-carb participants consumed almost no carbohydrates during the first week, limited carbs were introduced during the second week and their memories showed improvement with the revised diet. The study's co-author Holly A. Taylor, PhD commented on the bottom line, saying, "Although this study only tracked dieting participants for three weeks, the data suggest that diets can affect more than just weight."
Have you noticed that some diets affect your brain's ability to function properly?
