I think it's interesting to note that he tells you to research and to use crediable sites such as ones that end in EDU Here is his quote:
Search the Internet to find credible sources of information about any unfamiliar ingredients on the label before you buy. These include such as carmine, Quorn, and diacylglycerol. Credible Internet sources tend to be government or educational sites, which end in “.gov” or “.edu” rather than “.com.”
Interesting to note his site ends in "com" and earlier in the article he blames the government for the labling problems and ect... Hmmmmmm........
