ingredient decoder from Kashi in a magazine yesterday. They have a PDF you can download, print out and keep handy.
Kashi is definitely one of the companies I can trust when I buy food. The only thing I ever have to look out for is nuts, but that's something I can easily live with!
Basically the list they give includes ingredients that you will (green thumb) and won't (red thumb) find in their products. Next to each ingredient they give a two or three line snippet.
Some examples of green thumbs include acacia gum, oligofructose and glycerin. Some of the don'ts: BHT, Calcium perioxide and sodium benzoate.
I was able to cut mine out of the magazine and keep it around for reference. I hope you find their website useful. My list was rather incomplete, so I thought I'd share Kashi's "a little more complete" list with you. :)
