B12 I have already discussed on two separate occasions in this same thread, so I will not comment on it again.
One source of B6 is whole grains. It's also in nuts, such as peanuts.
Protein; My god, don't get me started. The Standard American Diet contains so much more protein from the huge quantities of meat eaten than is necessary for humans to thrive. Protein can literally be found in anything, and we don't need NEARLY as much as most people think we need. If you are concerned, excellent sources of protein are nuts and beans and whole grains. Unless you're anorexic, the risk of becoming deficient is negligible.
Phosphorus is present in beans, nuts, seeds, and cereals.
Sodium is in salt. Need more sodium? Just add salt. WOW.
Iron is present in green leafy vegetables, beans, peas, and other legumes. Whole grains, and seeds have it too. No problems here.
Manganese is only required in trace amounts anyway and can also be acquired from several different sources. It's in breads, cereals and grains in pretty hefty quantities. There are shittons of the stuff in pineapple.
A lot of the nutrients you mentioned (with the exception of B12, which does need to be supplemented somehow I agree) are available in trace amounts in almost all types of food. A diet with a wide variety of foods will for the most part ensure that you get enough of what you require.
vegetarian diets are excellent for kidney health, heart health, liver health, and galbladder health. it reduces fat in the body, reduces cholesterol (note: some people with a certain condition get WORSE cholesterol on vegetarian diets but that's very rare), and may ward off most forms of cancer.
Emphasis mine. Given that heart disease kills more people than anything else, I would consider reducing the risk of that to be a very high priority. Especially if heart disease runs in your family, as it does in mine.
vegetarian diets, however, increase levels of oxalic acid, potasssium, and zinc. That wouldn't be a problem, except when you get too much of it (which is easy on a vegan diet), you greatly increase the risk of testicular/ovarian cancer, or other genitourinary conditions.
I am not familiar with this. I'll get back to you after looking up more information.
I think you are incorrect about the difficulty in maintaining the presence of these nutrients in our bodies. But I could be completely wrong. In general, however, most vegetarians and vegans ARE undoubtedly healthier than the general public (possibly because the general public eats way too much fast food). As I stated a few posts ago, I do not believe there is anything wrong if someone merely cuts down the meat in their diet. For me personally, I consider the ethical reasons to be of utmost importance and would take a nutritional suplement if I were deficient in any nutrients. I have not needed to do this, though.
