    Does aspartame affect preference for sweetness?
    • Conclusion

      To date, adequately powered studies have not been conducted to evaluate the effect of aspartame on preference for sweet taste. 

      The 2009 update did not find new studies meeting the inclusion criteria for this question and the 2009 N&NNS Workgroup  concurs with the conclusion above formulated by the 2008 Aspartame Workgroup. .
