Following the ban of red dye No. 3 in the United States, experts weigh in on the potential health risks of red dye No. 40, yellow dye No. 5 and others.

The US Food and Drug Administration announced this month that it's effectively banning Red No. 3, the controversial artificial red dye found in food and drinks that's been linked to cancer. The decision comes 30 years after scientists first discovered links between the dye and thyroid cancer in animals.

Brian Ronholm: Well, this is an issue that’s been percolating for quite a long time. Back in 1990, the FDA made the decision to ban Red 3 in cosmetics, and that was because it was linked to cancer in animals.

The FDA banned the use of Red Dye No. 3 based on a petition asking that the agency follow a specific guideline.

The FDA's ban on Red Dye Number 3, set to take effect in January 2027, raises health concerns among local doctors who recommend reducing artificial food dyes to improve children's health and behavior.
