Aspartame is a methyl ester of a dipeptide used as a synthetic nonnutritive sweetener in over 90 countries worldwide in over 6000 products. The purpose of this investigation was to review the scientific literature on the absorption and metabolism, the current consumption levels worldwide, the toxicology, and recent epidemiological studies on aspartame. Current use levels of aspartame, even by high users in special subgroups, remains well below the U.S. Food and Drug Administration and European Food Safety Authority established acceptable daily intake levels of 50 and 40 mg/kg bw/day, respectively. Consumption of large doses of aspartame in a single bolus dose will have an effect on some biochemical parameters, including plasma amino acid levels and brain neurotransmitter levels. The rise in plasma levels of phenylalanine and aspartic acid following administration of aspartame at doses less than or equal to 50 mg/kg bw do not exceed those observed postprandially. Acute, subacute and chronic toxicity studies with aspartame, and its decomposition products, conducted in mice, rats, hamsters and dogs have consistently found no adverse effect of aspartame with doses up to at least 4000 mg/kg bw/day. Critical review of all carcinogenicity studies conducted on aspartame found no credible evidence that aspartame is carcinogenic.
The data from the extensive investigations into the possibility of neurotoxic effects of aspartame, in general, do not support the hypothesis that aspartame in the human diet will affect nervous system function, learning or behavior. Epidemiological studies on aspartame include several case-control studies and one well-conducted prospective epidemiological study with a large cohort, in which the consumption of aspartame was measured.
The studies provide no evidence to support an association between aspartame and cancer in any tissue. The weight of existing evidence is that aspartame is safe at current levels of consumption as a nonnutritive sweetener.

BACKGROUND: The role of sweeteners on cancer risk has been widely debated over the last few decades. To provide additional information on saccharin and other sweeteners (mainly aspartame), we considered data from a large network of case-control studies. METHODS: An integrated network of case-control studies has been conducted between 1991 and 2004 in Italy. Cases were 598 patients with incident, histologically confirmed cancers of the oral cavity and pharynx, 304 of the oesophagus, 1225 of the colon, 728 of the rectum, 460 of the larynx, 2569 of the breast, 1031 of the ovary, 1294 of the prostate and 767 of the kidney (renal cell carcinoma). Controls were 7028 patients (3301 men and 3727 women) admitted to the same hospitals as cases for acute, non-neoplastic disorders. Odds ratios (ORs), and the corresponding 95% confidence intervals (CIs), were derived by unconditional logistic regression models. RESULTS: The ORs for consumption of saccharin were 0.83 (95% CI 0.30-2.29) for cancers of the oral cavity and pharynx, 1.58 (95% CI 0.59-4.25) for oesophageal, 0.95 (95% CI 0.67-1.35) for colon, 0.93 (95% CI 0.60-1.45) for rectal, 1.55 (95% CI 0.76-3.16) for laryngeal, 1.01 (95% CI 0.77-1.33) for breast, 0.46 (95% CI 0.29-0.74) for ovarian, 0.91 (95% CI 0.59-1.40) for prostate and 0.79 (95% CI 0.49-1.28) for kidney cancer. The ORs for consumption of other sweeteners, mainly aspartame, were 0.77 (95% CI 0.39-1.53) for cancers of the oral cavity and pharynx, 0.77 (95% CI 0.34-1.75) for oesophageal, 0.90 (95% CI 0.70-1.16) for colon, 0.71 (95% CI 0.50-1.02) for rectal, 1.62 (95% CI 0.84-3.14) for laryngeal, 0.80 (95% CI 0.65-0.97) for breast, 0.75 (95% CI 0.56-1.00) for ovarian, 1.23 (95% CI 0.86-1.76) for prostate and 1.03 (95% CI 0.73-1.46) for kidney cancer. A significant inverse trend in risk for increasing categories of total sweeteners was found for breast and ovarian cancer, and a direct one for laryngeal cancer. [b]CONCLUSION: The present work indicates a lack of association between saccharin, aspartame and other sweeteners and the risk of several common neoplasms.
BodyBuilders, Fitness Models, Models all live on Crystal Light and other aspartame containing drinks before contests and photoshoots. You don't see those populations coming down with abnormally large pre-mature death cases. Do you? And bodybuilders are dying prematurely because of excessive steroid use, not exccessive diet coke drinking.
