Psych Central, Mar. 14, 2011In 1993, Dr Walton, who is a psychiatrist, conducted a study of 40 patients with unipolar depression and a similar number without a psychiatric history. The subjects were given 30 mgs per kg of body weight a day of aspartame or a placebo for 20 days (about equal to daily consumption if it completely replaced sugar).
Thirteen individuals completed the study, then an institutional review board called the project to a halt “because of the severity of reactions within the group of patients with a history of depression.” In a smaller, shorter crossover design, “again there was a significant difference between aspartame and placebo in number and severity of symptoms for patients with a history of depression, whereas for individuals without such a history there was not.”
Accordingly, the author concluded that “individuals with mood disorders are particularly sensitive to this artificial sweetener and its use in this population should be discouraged.”
