I came across this site today when I was attempting to research ingredients in a certain product. It contained quite a bit of information. It shows the good and bad things in each product. It also gives each product a health score on a meter which the little vegan has been playing with for an hour now. She has enjoyed looking at non-vegan food and how bad it is for you (though I will admit not all our vegan choices have rated very high.)
The link takes you to our search result for tofu. You may search for anything you like. Have fun!
