Vegetarian and vegan foods are often marked with labels, but look out for anything that says it contains dairy, eggs, or fish. See this explanation to see why you shouldn’t drive yourself crazy by spending hours at the grocery store reading labels though! When it comes down to it, slaughterhouses don’t exist because you may or may not be eating a trace byproduct. Animals are slaughtered by the billions because people eat their flesh, eggs, and milk. You can find a list of amazing vegan foods on our “Guide to Vegan Grocery Shopping” and “Alternatives to Animal-Derived Foods” pages. Also, if you are unsure about an ingredient, you can always call a company to ask.
