Commercial chips and crackers often have many unhealthy ingredients, chemicals, and dyes.
Here are a few (from labelwatch.com):
Dyes: Blue 1, Blue 2 (Lake), Red 40 (lake), Yellow 5 (Lake), Yellow 6 (Lake)
Unhealthy or cautionary ingredient: Enriched Flour, High Fructose Corn Syrup, Partially hydrogenated oils (cottonseed, soybean, coconut, vegetable shortening, etc.), Trans Fat, TBHQ, Artificial Flavor, Autolyzed Yeast, Disodium Inosinate, Disodium Guanylate,Hydrolyzed Corn Protein, Monosodium Glutamate, Sodium Metabisulfite
Common food dyes, such as Yellow 5, Red 40, and 6 others, have many risks, such as hyperactivity in children, cancer (in animal studies), and allergic reactions. Britain and the European Union have stopped the use of dyes. The Center For Science in the Public Interest (CSPI) shows how Kellogg’s Nutri-Grain bars are colored naturally in Britain with Beetroot red, Annatto, and Paprika, but in the USA, chemical food dyes Red No. 40, Yellow No. 6, and Blue No. 1 are used. Food dyes are deceptive, making food appear to be healthy.
