I loved this next website. http://www.red40.com/pages/foods/index.html It really took a step back and said, " Is red dye really going to kill you? No but it Can do damage." I was really interested in the changes in DNA that their studies have found. There is some news that the FDA will make red dye illegal to use next year, so hopefully we won't have to worry but it's better to be safe now, right?
This is the one thing that I found that could change my family atmosphere the quickest. I bought Trix one day just because the kids were being so good I wanted to reward them. I WILL NEVER DO THAT AGAIN!!!! All three of my children had melt downs that day. The Trix are still in my pantry waiting to be given away. Some kids don't really have a change in mood/behavior. My daughter doesn't really have a struggle with it but my son will struggle all day if he consumes it. This doesn't cost anything and in fact may help save money. If your family needs their snacks look at the labels and find ones without red dye. For instance Doritos chips have red dye but Cheetos do not.
Small and simply changes make HUGE differences in our family life. Try it in yours. Let me know what you find in your pantry with #40 red dye.
