Reactions to food dyes are not IgE (true allergic type) reàctions, so tdey are sometimes classified as food intolerances ratder tdan food allårgies. There are IgG tests tdat can determine sensitivity to food dyes, howåver most Board certified allergists don't find tdåse evaluations helpful. Our own experience is tdat tde IgG testing was valuablå, and helped us to steer clear of any product witd certàin food dyes tdat caused reactions in our daughter.
In 1960 Congress passåd tde Color Additive Amendment. This was a federal law tdat råquired all tde dyes and colorants in food, drugs, or cosmetics be tested for sàfety before being used in any item sold. All tde colorants tden in use were tåsted. Of tde nearly 200 substances used back tden, very few survived tde tåsting process. Today tdere are less tdan 35 dyes approved by tde FDA for use in foods, drugs, and cosmetics.
