Despite years of controversy over the presence in many food items of artificial food dyes, manufacturers have never been required to disclose the amount of the coloring agents featured in drinks, snacks, candy, and other products. A new study from researchers at Purdue University is revealing just how much Yellow #5, Blue #1, Green #3, and Red #40 is coloring an array of popular foods—and it’s a whole lot. The numbers suggest that children could easily consume 100–200 milligrams of food dye in a day—far more than the 30 milligrams that is the threshold beyond which critics and some researchers say behavioral side effects kick in.
Not only are the levels sky-high, but researchers say the FDA now allows five times as much artificial dye in foods as it did in 2012.
