State lawmakers on Thursday voted to prohibit California schools from serving food additives used in Flamin’ Hot Cheetos, Twinkies and other fluorescent snacks. The move, backers argue, is necessary to limit intake of dyes that have been linked to worsened behavioral issues in kids who have attention-deficit/hyperactivity disorder, or ADHD.

The California Legislature has passed a bill banning red dye No. 40 and five other chemicals from use in public school foods.
