In this new study, researchers took several groups of rats and either fed them diets high in glucose, fructose, or artificial sweeteners (aspartame or acesulfame potassium). Acesulfame is sold in stores at Sunnett or Sweet One, and aspartame is sold as Equal or NutraSweet. Both are currently approved artificial sweeteners by the FDA.
Within three weeks the researchers found discernable differences between the groups per blood samples collected. They noted that the artificial sweeteners appeared to change the way their bodies processed fat and energy overall. They also noticed that the acesulfame potassium accumulated in the blood and had a negative impact on the cells lining the blood vessels.
Bottom line? Don’t think that switching to artificial sweeteners is the answer. For one, how many thin people do you see walking around drinking diet sodas all day? They don’t seem to work. This study helps us understand why. Also, continuing to drink sweet beverages hinders one’s ability to acclimate to lesser sweetened beverages and foods. It keeps the sweet desire active, per say, and doesn’t solve the problem of cravings. In fact it can make things worse by initiating an insulin response but, with no actual sugar entering the body, you end up with lower blood sugar and a “crash,” so to speak. The craving cycle continues.
