Wow, you guys/gals are fast! I've been typing too much. lol!
beksbks, why do you say that it is difficult to get enough protein on a Vegan diet? What is your source of information? I agree that a "vegetarian" diet consisting of prepared, manufactured foods would be highly deficient. I am in a gradual transition. I finished off the last of my eggs yesterday for breakfast. I had prunes and bananas for snacks between meals. I ate a peanut butter and pineapple jelly sandwich for lunch. At dinner time I ate vermicelli with meatless spaghetti sauce, black beans (beans, onion, garlic, bell pepper, seasonings) with tomato salsa and organic blue corn chips. Breakfast today included fresh bananas and oatmeal sweetened with stevia. I made some iced tea with stevia sweetener, too.
shamus, you didn't really eat a vegetarian diet if you included fish. Also, I'm only guessing, but you may have suffered from iron deficiency with that diet. One of my sources indicates that dairy products including cheese may hinder iron absorption. Honestly, I don't know either. It is just a guess on my part.
inkling, humans and other primates share characteristics with herbivores such as type and form of teeth, well developed salivary glands, alkaline saliva, weak stomach acid, and long intestinal tract. Even chimpanzees consume 95% of their diet from plant sources, and a major portion of the remaining 5% is termites (for their b12 content). High protein consumption is cited by different studies as a possible factor in the development of osteoporosis. I admit that the result of any scientific study can vary with its design. A book that I am reading by John Robbins (Diet for a New America) cited numerous studies made in the 70's and 80's that were negative towards the dairy industry. Naturally, the dairy industry has used its financial resources to fund its own studies. Personally, I love milk, cheese, and ice cream. But, I don't see them as the "health" foods that the industry has promoted for decades. YMMV.
David, what I am learning is that getting enough protein is a non-issue that has been popularized in our culture. A truly protein deficient diet would amount to starvation or at least severe malnutrition. The real problem is excess protein in our modern diet.
