I've been a vegetarian for about 8 years. Big switch - I was raised in the midwest where you eat meat at EVERY meal! The animal products I do eat, I try to get the humane ones (free range organic eggs, family farm milk, etc.). Yes, they're more expensive but I believe in putting my money where my mouth is. Oh - what a shock, finding out that there are animal enzymes in cheese!!! And I'm a cheese-a-holic! Now I have to shlep all the way to Whole Foods once a month to get non-animal rennet cheese (at $5.99 a bag for shredded cheddar - yikes!!).
