People suffering from phenylketonuria or tardive dyskinesia should avoid aspartame, warns Healthline. Phenylketonuria patients have too much phenylalanine in the blood, since they are unable to process it effectively. Aspartame is therefore highly toxic for them. On the other hand, aspartame worsens the uncontrolled muscle movements triggered by tardive dyskinesia, a condition which is thought to be caused by schizophrenia drugs.

Aspartame is an artificial sweetener used in products such as yogurt, diet drinks, cereals and chewing gum. It is roughly 200 times sweeter than sugar and is made of phenylalanine and aspartic acid, both of which are naturally occurring amino acids. When the body digests aspartame, some of the aspartame breaks down into methanol, which is toxic in large quantities. However, the amount of methanol formed from aspartame is very low, states Healthline.

Despite its toxicity claims, the use of aspartame is supported and approved by health-related organizations and regulatory agencies such as the Food and Drug Administration, World Health Organization, American Dietetic Association, American Heart Association and United Nations Food & Agriculture Organization, says Healthline. The Food and Drug Administration recommends an acceptable daily intake of not more than 50 milligrams per kilogram of body weight of aspartame, while the European Food Safety Authority recommends no more than 40 milligrams per kilogram of body weight of aspartame.
