Hi kristina! I am an ovo-lacto vegetarian. I initially decided to "go veggie" because I come from a meat and potatoes kind of family and I just wanted to see if I could maintain a healthy vegetarian lifestyle. I was also basically interested in improving my overall health. (i waited until I moved away from home though!) as it turns out I have done so quite nicely. In the last year, though, I have started including fish in my diet (tuna, whitefish, salmon, etc) because there are convincing studies that link fish consumption with lowered cancer risk. I have a lot of cancer in my family, so i'm all about doing anything I can to cut my own risk factors. I personally feel that this choice is right for me. It was never really an ethical decision for me to stop eating meat, but I can identify with your desire to not kill animals unnecessarily. Since I went veggie I have decided that humans, especially americans, eat far more protein than necessary and that there are satisfying and more humane methods of finding the proteins we do actually need without killing animals. It kind of grosses me out now to see someone dig into a steak.
But that is me. The question is you. You are a recovering anorexic. (congratulations!) i'm not qualified to say what you need to be healthy. But I would think that you might want to consider adding some animal protein to your diet, even if it's not actual animal flesh. To me organic (if I can find organic) dairy products and eggs are a healthy part of my eating habits. I enjoy cheese, yogurt, milk, etc. Also, don't just rely on tofu and nuts. Do you eat beans and rice? I could practically live on the stuff! It's considered a perfect protein. You could add protein powder to a fruit smoothie too. Your doctor probably knows what's best for you. Consider all the options carefully and work with him/her to create an eating plan that you can live with. If you want to be a vegan when you reach a healthy weight, perhaps you could arrange for that. But for now, listen to your doctor a little and focus on being well. Don't feel guilty if you do decide to relent a little. Saving animal lives is honorable, but your healthy life is more valuable in my opinion. I apologize if that sounds harsh, but I feel it's the truth. I wish you nothing but the best as you work toward your goal!
