Yes the natural stuff is better and I tend to avoid the artificial dyes anyways, which can be hard at time because it seem like almost anything that has color in it anymore is artificial other than fruit. I was just wondering what causes this problem and why it really only seems to be certain kinds of dyes.
Not an intolerance, but it is a sign that your body is not processing it properly, time to get off the artificial dyes, and start eating natural. funny how the body talks to us, and we don't listen.
