Aspartame And Acesulfame K And Artificial Colors

Aspartame and acesulfame K are artificial sweeteners. Aspartame is made from two amino acids, while acesulfame K is a synthetic potassium salt. Artificial colors are synthetic dyes, often derived from petroleum, used to add visual appeal to foods.

These ingredients are often used together in sugar-free or low-sugar foods and beverages, such as gelatin desserts, diet sodas, and candies, to provide sweetness and appealing colors. They help enhance the visual and taste experience of processed foods.

Aspartame and acesulfame K are approved by the FDA as food additives. JECFA has evaluated both and set acceptable daily intakes. In 2023, the International Agency for Research on Cancer (IARC) classified aspartame as possibly carcinogenic to humans (Group 2B), while JECFA maintained its existing acceptable daily intake. Artificial colors are also approved by the FDA. In April 2025, FDA announced a plan to phase out petroleum-based synthetic dyes, including Red 40, Yellow 5, Yellow 6, Blue 1, Blue 2, Green 3, Citrus Red 2, and Orange B. FDA revoked Red 3 for food in January 2025, with manufacturers having until January 2027 to comply. Scientific evidence on potential links between artificial colors and hyperactivity in children is mixed.
