@abcnews: Hundreds of people gathered outside the WK Kellogg headquarters in Michigan this week, calling for the company to hold up its promise to remove artificial dyes from its breakfast cereals sold in the U.S. Nearly 10 years ago, Kellogg's, the maker of popular cereals such as Froot Loops and Apple Jacks, committed to removing such additives from its products by 2018. While Kellogg's has done so in other countries, including Canada, which now makes Froot Loops with natural fruit juice concentrates, the cereals sold in the U.S. still contain both food dyes and a chemical preservative. #news #kellogg #cereal
