not understand the importance of a reliable supply of vitamin B12. Nutritional myths have a way of going from one extreme to the other - either something is such an issue that people should not be vegan, or it is not important at all. The truth is often in the middle. Protein, calcium, and vitamin D are examples. People once believed that in order to rely on plant proteins, you had to combine particular foods at every meal. We now know this is not true, but in countering the myth, claims have gone from "You don't need to combine proteins," to "It's easy to get enough protein on a vegan diet," to the harmful "It's impossible not to get enough protein!" On average, vegans get enough protein, but vegans who avoid legumes and soyfoods might not be getting enough and could feel unhealthy. As for calcium, you can pick and choose a few studies to support the idea that animal protein, including protein in milk, is the main cause of osteoporosis. And following this line of logic, it would make sense that vegans therefore do not need to worry about osteoporosis since they are not eating animal protein. I wish it were true, but someone who evaluates more of the research will likely conclude that vegans, like non-vegans, should ensure good sources of calcium and vitamin D on a daily basis. I would like to see vegan advocates promote the diet in such a way that we minimize the chances
