After learning the effects of food dyes, I haven’t had jello in over a decade.

Does Jell-O use food dyes?

Yes, most Jell-O contains artificial colors, including red 40, yellow 5, and yellow 6, which are derived from petroleum and may have negative health effects. Some say that these dyes may promote cancer because they contain benzidine, a known carcinogen. Red 40 is also a common ingredient in candy, cereal, baked goods, gelatin powder, drugs, and cosmetics. Some say that side effects of red 40 include hyperactivity, behavioral changes, allergic reactions, hives, asthma, sneezing, watery eyes, skin irritation, and migraines.
