We all know of diet drinks and sugar-free desserts. Such foods have ingredients that are sweet, but low in calorie. The temptation to savor and relish sweet foods without paying the price of high calorie intake is pretty tempting, isn't it? But does taking food items with a mismatch in sweetness and calorie content actually work on our brains? Can our brain detect the disparity?
Maria and colleagues wanted to understand the affect of discrepancy between the sweetness of the food and its calorie content on the brain's response and metabolism. By providing people drinks that were of the same nutritional value, but varying in calorie, they found that the body responded the best when the two things, sweetness and calories, matched. This suggested that calories are not the only factor that trigger metabolic and mental responses. It could be that the brain's reward circuits better register foods that match in their sweetness and nutritional content. This is of great importance because we live in a world where increasing amounts of food contain such mismatches. To know more, please listen to Maria.
