A HPLC-MS/MS method is presented for the simultaneous determination of frequently used artificial sweeteners (ASs) and the main metabolite of aspartame (ASP), diketopiperazine (DKP), in environmental water samples using the direct-injection (DI) technique, thereby achieving limits of quantification (LOQ) of

Despite safety reports of the artificial sweetener aspartame, health-related concerns remain. We prospectively evaluated whether the consumption of aspartame- and sugar-containing soda is associated with risk of hematopoetic cancers. We repeatedly assessed diet in the Nurses' Health Study (NHS) and

Aspartame is a synthetic sweetener that has been used safely in food for more than 30 years. Its safety has been evaluated by various regulatory agencies in accordance with procedures internationally recognized, and decisions have been revised and updated regularly.
T J Maher et al.
Environmental health perspectives, 75, 53-57 (1987-11-01)
The artificial sweetener aspartame (L-aspartyl-L-phenylalanyl-methyl ester), is consumed, primarily in beverages, by a very large number of Americans, causing significant elevations in plasma and, probably, brain phenylalanine levels. Anecdotal reports suggest that some people suffer neurologic or behavioral reactions in

Toxicology is based on the premise that all compounds are toxic at some dose. Thus, it is not surprising that very large doses of aspartame (or its components--aspartate, phenylalanine, and methanol) produce deleterious effects in sensitive animal species. The critical
