Unfortunately, a blockbuster new study published in the journal Food and Chemical Toxicology finds that blue dye used in edible products might be doing more to our bodies than we thought.
The research team, out of the Slovak University of Technology, studied two blue dyes, Patent Blue and Brilliant Blue. The former is banned from food products in the United States, but Brilliant Blue (also known as FD&C Blue No. 1) is used in food, textiles, leathers, and cosmetics in several countries including the U.S.
“[Brilliant Blue] is one of the most commonly used blue dyes,” says study co-author Jarmila Hojerová, an associate professor at the Slovak University of Technology and president of the Slovak Society of Cosmetology.
So it must be safe, right?
