An expert from Syracuse University says synthetic food dyes are common in many foods. Examples include Red Dye 40, Yellow 5 and 6, and Red Dye 3. Manufacturers add these petroleum-based colorings so products look more appealing.
The expert says dyes are not toxic immediately, but the main worry is long-term effects on children's development and behaviour. Research finds a genetic component, and some countries have banned these ingredients.
Major companies now have until 2027-28 to phase these ingredients out following FDA guidance. Removing color may make companies add more sugar and fat. Consumers should pay attention to overall diet quality and watch sugar, saturated fat, protein and fibre.
