WSJ report on Robert Kennedy Jr's efforts to remove artificial dyes in cereals used by Kellogg, General Mills, that are harmful to health and wellbeing of children and adults. RFK Jr is the nominee for Secretary Health and Human Services. Cereal made in Canada for Fruit Loops uses natural ingredients juice from carrots, water melon and blueberries to get the same colors. In the US artificial dyes are still used. When General Mills stopped using artificial dyes in Trix it changed the color and tasted bland according to food scientists in the company, leading to consumers not supporting the change. Large cereal companies are not taking the action needed when it comes to educating the public about the need for the change and making changes for healthy cereals.
