Mars introduces naturally colored candies amid industry-wide dye overhaul

Mars announced that its upcoming candy line will rely on natural colorants sourced from plants and algae, eliminating the synthetic dyes traditionally used in products such as M&M’s and Skittles. The rollout, slated for Amazon by the end of August, mirrors commitments from WK Kellogg, General Mills and Kraft Heinz to remove artificial colors from various food categories over the next few years. This industry movement is tied to Health and Human Services Secretary Robert F. Kennedy Jr.’s initiative to eliminate petroleum-based dyes from the U.S. food supply, a goal pursued through voluntary industry agreements rather than mandatory bans.

Scientific reviews, including a comprehensive California OEHHA assessment, have linked synthetic dyes to increased restlessness and inattention in children, though they do not prove a direct cause of ADHD. While natural alternatives avoid the specific chemicals under scrutiny, experts caution that some plant-based pigments, such as carmine, can trigger allergic reactions and that overall safety data remain limited. The debate highlights the need for rigorous testing of any color additive, given that dyes provide no nutritional benefit and are primarily cosmetic. Critics argue the FDA has been slow to act on emerging safety evidence, relying instead on industry self-regulation.
