This is why I believe people should do their research and talk to a veg(itatri)an first, then ease into the lifestyle. Many people get so excited to go hardcore veggie right away but live off of such small variety of foods (Had they known that Oreos, Jell-o Pudding mix, cereals, unglazed Poptarts, Act II Butter Lover's popcorn, Graham Crackers, and Hershey's Syrup are vegan, they may have stuck with it for a little longer). They get tired of it all after a week. That's when they go back to eating quick meaty meals regularly, thinking they 'failed the veg test'. Basically, I'd rather tell a meat-lover who wants to save animals to eat less meat than go cold turkey vegan/strict vegetarian!
How the heck do you classify good junk food from the bad junk food? Easy I tell you! Use these four cheater checkpoints to use so you don't waste your time staring at a box of [insert deliciousness here] reading through an endless list of crap called ingredients.
2. Cholesterol. Anything that has something other than 0 for cholesterol in the Nutrition Facts should automatically be placed onto the floor, stepped on harshly, rolled over by the shopping buggy, and gently set back on the shelf. Your body makes it's own cholesterol; plants do not. It's a sure sign of hidden animal in your food.
3. Allergen Label. Flip the package over to the nutrition facts side for a sec. An allergen statement in bold letters at the bottom of the ingredients list should tell you plainly if it has shellfish, eggs, or milk in it.
**It's ok if you also see "produced in a facility that processes X". This does not mean that X is in that food.
4. Simple ingredients. Pick products that have a list of 10 or less ingredients. You shouldn't have a difficult time pronouncing them either. Large food manufacturing companies love to throw in lots of unneeded ingredients. Some of them are modified to enhance your taste buds, making you want second and third helpings (MSG). Others are meant to adjust the consistency or texture of the product (gums and syrups).
