Hi, a study published in April 2006 sponsored by the National Cancer Institute involved 340,045 men and 226,945 women, ages 50 to
69, found no statistically significant link between aspartame
consumption and leukemias, lymphomas or brain tumors. The study used surveys filled out in 1995 and 1996 detailing food and beverage consumption. The researchers calculated how much aspartame they consumed, especially from sodas or from adding the sweetener to coffee or tea.
