Opinion: RFK Jr.’s synthetic dye bans miss a much bigger problem
Red dye No. 3 isn’t the real danger — it’s the sugar and refined carbohydrates that deliver it
As a professor of physiology, I study how scientific evidence gets translated, sometimes clumsily, from the lab to real life. Whether it’s scaling dietary supplements to humans or using biomimicry to mitigate sports concussion, my work often centers on the fine line between meaningful evidence and misleading extrapolation.
That’s why I was immediately skeptical when the Food and Drug Administration announced its decision to ban synthetic food dyes like the controversial red dye No. 3.
