When your body breaks down aspartame (an artificial sweetener), it turns into three things you already get from foods like meat, beans, and fruit—and your body doesn’t store them up over time.
When people eat or drink things with aspartame (like diet soda), their blood phenylalanine goes up — and this happens more if they haven’t eaten recently, even if they don’t have the genetic condition PKU.
Eating or drinking things with aspartame doesn’t seem to raise or lower blood sugar, insulin, or fat levels in people with diabetes, according to some small studies.
Eating or drinking things with aspartame might raise the amount of methanol in your blood, but we don’t yet know if that’s actually harmful or just a harmless blip.
Some studies say eating aspartame doesn’t mess up your metabolism, but the studies aren’t very strong or many — they just watched people instead of testing them in controlled experiments.
