Scout's take
FD&C Red #40 is a synthetic petroleum-derived food dye that has been linked to hyperactivity in children, potential carcinogenicity, and allergic reactions. It is banned or restricted in several European countries and serves no nutritional or functional purpose — it exists solely for cosmetic color.
