Arguing with me that I could not possibly have experienced a cause and effect because some people didn't hold enough large enough placebo controlled double blind studies (I say this because double blind studies have studied this exact phenomenon, and triggered the retraction of some of these dyes in other countries) is just insulting after a while.
We know so little about nutrition and how different individuals process different nutrients that the scientific consensus on healthy food habits, weight loss, etc have shifted dramatically over the years. We are facing an obesity epidemic in the US. A little humility would be nice in the face of what clearly is not working for the majority of the population.
I mean, it's just food dye for God's sake, what's the "scientific" argument that foods must contain artificial colors?
