I stumbled across a list of animal ingredients and their alternatives as compiled by PETA. This list is a great reference point, and I wanted to share it with you, we've added it to our vegan resources page as well.
Animal ingredients are used not because they are better than vegetable-derived or synthetic ingredients, but because they are generally cheaper. Today’s slaughterhouses must dispose of the byproducts of the slaughter of billions of animals every year and have found an easy and profitable solution in selling them to food and cosmetics manufacturers.
Jane and I feel that avoiding these by-products is not nearly as important as avoiding the animal products from which they are derived. If the number of animals slaughtered is reduced, the availability of animal by-products will also be reduced, therefore driving up the price so other alternatives will be sought out by the manufacturers. In the meantime, they are everywhere. This list, while not comprehensive, provides some information for anyone confused about what they're reading on the labels of the products they're buying.
