The effect seems to be caused by a metabolite of aspartame, called PHE. So you could check whether stevia or erythritol produces the same metabolite.
PHE? That was not mentioned in the article. What was mentioned was _phenylalanine_, which is one of the essential amino acids that the human body needs but cannot synthesize itself. We MUST get it from food. It is present in practically all the food (protein) we eat. Particularly good sources of phenylalanine include eggs, chicken, liver, beef, milk, and soybeans.
