According to their tallying, vegans have the least expensive diets, and meat eaters have the priciest, which certainly flies in the face of the arguments that vegetarianism is a choice limited to the hippie fringes and the bourgeoisie.
I like the message, but I take issue with some of the numbers. For instance, I don't know where they are getting their yogurt, and I know New York is expensive and everything, but I can't find a single serving of healthy yogurt for 80 cents anywhere I do my groceries, and a tuna cheddar melt for just over a buck seems unrealistic.
