One problem with being a vegetarian is you need to be very careful to monitor exactly what you eat and typically most don't. Either that or they use a number of supplements to replace simple, and complex, amino acids that they don't get from their regular diets. Supplements = chemicals, hard to say how good that is for you. Some studies feel that vegans, in particular, may infact do long term damage to organs because of a lack of certain proteins that they don't properly substitute for in their lack of meat.
Not saying it's good or bad, but I was a chemist at one point, did a bunch of work in human biology and micro-biology, and I read lots of material. Lots of great evidence to weight loss, and factors like that, but not a terribly great relationship of those being "healthier" than someone who ate meat and had a good diet. Exercise was the key to health in combination with a good diet. Vegans who didn't exercise weren't any "healthier".
Living in Alberta is 90% of living in Texas though.... some people BBQ for their midnight snack
