J Toxicol Environ Health. 1976 Nov;2(2):401-15. Use of aspartame by apparently healthy children and adolescents. Frey GH. This study was conducted to determine the effects and the differences, if any, resulting from the ingestion of aspartame (sweetener) versus sucrose. A 13-wk, double-blind study was conducted using 126 apparently healthy children and adolescents as panelists. Individuals were randomly assigned in a double-blind design to aspartame or sucrose in each of five age groups; dosage levels were assigned according to age and weight groups. Physical examinations and special eye examinations were performed at the beginning and end of the study. Other parameters determined including laboratory tests of liver and renal function, hematologic status, and plasma levels of phenylalanine and tyrosine. Clinically significant differences in laboratory parameters measured could not be demonstrated; all mean values were within normal limits. No unusual findings were observed in phenylalanine or tyrosine levels. All phenylpyruvic acid and methanol determinations were negative. No important physical changes occurred, and no product-related side effects were reported.
