To whom it may concern:
I am writing to request that you make your products available without aritificial coloring. My children react strongly with negative behaviors every time they eat anything with food colorings such as Red # 40, Yellow #5 and Yellow #6. Research has shown these ingredients to be problematic. Please make products available that are naturally colored. It is frustrating that even things such as Macaroni and Cheese and Vanilla Pudding have coloring added. I find the additives to be unnecessary and detrimental to my children's health.
