There is a common misconception that 'vegetarian' automatically means 'healthy'. This couldn't be further from the truth. If anything, vegetarians have to be even more careful about what they eat, to ensure they're getting enough essential nutrients. Many products marketed to vegetarians are also quite suspect. One of these is the veggie burger.
Don't get us wrong, we've tried some pretty decent and healthy homemade veggie burgers in our time, but some of the mass-produced supermarket brands should be absolutely avoided. Artificial flavors and carcinogenic coloring are common ingredients in many vegetable burgers, so always be careful when you shop and make sure you read the label. The great news is that there are plenty of healthy veggie burgers out there, you might just have to look a little harder. Check out your local health food store if your supermarket isn't helpful.
