Aspartame is a sugar substitute that is approved by the Food and Drug Administration. It is made of aspartic acid and phenylalanine and is much sweeter than sugar, reports Healthline. Critics claim that aspartame causes a number of disorders, including multiple sclerosis, lupus, fibromyalgia, depression, vision problems and cancer. However, many studies confirm that it is safe to consume in limited amounts, according to the U.S. Food and Drug Administration.

When the FDA first approved the use of aspartame, there was a concern about one study that showed aspartame might cause brain damage or brain tumors. However, the study was proven to be false because humans would never consume such a large dosage of aspartame, explains Healthline.

People diagnosed with phenylketonuria need to avoid aspartame because large amounts of phenylalanine can build up in their body and they can suffer brain damage, reports Healthline. People who take medication for schizophrenia should also avoid aspartame, because it can worsen tardive dyskinesia, a side effect of some schizophrenia medications.
