So many people get freaked out about not getting enough protein. Does anyone know of anyone that has Kwashiorkor? I am going to say that I highly doubt it. That is what you get when you have a diet low in protein. And in order to get that disease, you would have to be malnourished. So I tell people to relax and eat all the good stuff (and yes I know there are unhealthy vegetarian/vegans) and your body will take care of the rest.
I am slightly anemic, but I have not changed my diet to add meat back into it at all. I still feel fine, I just can't give blood. I can live with that. And if I want I can add some iron supplements if I so choose. But protein is everywhere and in all foods. Your dark leafy greens can rival any steak out there and without all the fat and cholesterol and with all the good stuff to go with it, such as fiber. And lest we forget those super grains that are out there.
You are right, not many people with a diagnosis of "Kwashiorkor", these days it's called Protein Calorie Malnutrition and that diagnosis crosses my desk at least 3 times a week. Also, Anemia is not a good thing, you may feel fine now, but it will at some point be detrimental to your health.
