Iodine deficiency:
http://www.vegansociety.com/html/food/nutrition/iodine.php
You'll need to take supplements for iodine if you live in the UK or any other country in the world that does not have iodized salt.
And down 1 paragraph from that
That's interesting. Now that you are consuming less iodine, the vegetables increase the body's demand for iodine.
Iodine content in fruits and vegetables depends on the soil in which they are grown. The iodine in milk comes from feed supplements and disinfectants.
I don't take supplements, and the little salt I put in my food is sea salt which contains iodine. I like to toast seaweed and crumble it over top of my salad. Thereby easily satisfying my RDA of iodine.

Calcium:
The majority of calcium and magnesium for meat eaters and non-vegan vegetarians comes from milk and cheese. For vegans, it comes from nuts and calcium pills.
Where you get calcium is just as important as how much. Look back at the USDA osteoperosis study I posted,(courtesy your suggestion) higher intake of calcium by omnivores
did not increase bone growth. In fact studies suggest that the higher acidity of the animal based foods can actually lead to a net loss of bone mass.
As for plant based sources for calcium;
Here is a good resource.

Essential means it is needed by humans but cannot be produced by humans. The greatest sources of other protein building blocks (amino acids) are other creatures made of protein, such as birds, bovine, and fish. Essential amino acids are also found in certain types of plant oil.
The nine essential amino acids are also found in plant foods. Not all plant foods are complete, (contain all nine) but as long as you are getting enough calories and eat a variety of foods there is no need to concern oneself with getting enough protein.
http://www.vrg.org/nutrition/protein.htm
It is very easy for a vegan diet to meet the recommendations for protein, as long as calorie intake is adequate. Strict protein combining is not necessary; it is more important to eat a varied diet throughout the day.
To much protein is more likely to cause health problems than too little. To my knowledge, there is not a single medical case of someone suffering a protein deficiency, while still consuming adequate calories.
Another interesting point about protein.
http://72.14.253.104/search?q=cache...er+cancer+connection&hl=en&gl=us&ct=clnk&cd=2
High protein intakes of 20 to 25 percent of calories may enhance tumor growth whereas low protein levels suppress it.
Note, when the protein is plant based, high level intake of protein
does not enhance tumor growth.

Iron:
All animals require iron, so eating anything from an animal will have iron in it, including milk. Vegans need to each spinach or take supplements.
There are many other good sources of iron for vegans besides spinach. Not that I don't eat my share of spinach.
http://www.vegsoc.org/info/iron.html
Good sources of iron for vegetarians include wholegrain cereals and flours, leafy green vegetables, blackstrap molasses, pulses such as lentils and kidney beans, and some dried fruits.
Despite iron from plant foods being less readily absorbed research has shown that vegetarians are no more likely to suffer from iron deficiency than non-vegetarians. Draper & Wheeler (1989) have stated there is no indication of increased prevalence of iron deficiency amongst vegetarians. Anderson (1981) found the iron status of long-term vegetarian women to be adequate, despite a high intake of fibre and phytate.

Vitamin B12:
Vegans need to take more pills for this one.
Wrong again, although many dietitians recommend B12 supplements they are not necessary. Rice milk and Soy milk are both supplemented with B12. However I get my B12 from nutritional yeast, which when mixed with ground walnuts makes a very tasty and nutritional substitute for parmesan cheese.
Dirt is also a very good source of B12, but I dropped that from my diet when I was two or three years old. Although I still sometimes eat fresh roots with only a cursory rinsing.
ShawnD said:
Vitamin D:
Another vitamin found in all animals. Vegans do not consume animals, so they rely on supplements.
Once again I cannot see this as a good reason to slaughter a living creature. There are far more benign ways to get ones RDA of vitamin D.
Me, I like the sun.
http://dietary-supplements.info.nih.gov/factsheets/vitamind.asp
Sun exposure is perhaps the most important source of vitamin D because exposure to sunlight provides most humans with their vitamin D requirement

Now for the question of how to fill each of these crucial health demands. A normal vegetarian can get all of these from drinking a glass of milk.
And what else are they getting with that glass of milk.
Amazing I went to the http://www.nationaldairycouncil.org/NationalDairyCouncil/
I had to go navigate through five pages of milk promotion in order to get to what I thought would be nutritional information. Where I arrived finally was http://www.nationaldairycouncil.org/NationalDairyCouncil/Nutrition/Products/MilksNutrientPackage.htm Another slick milk promo.
Fortunately I was able to find much better sources of information. The http://www.fns.usda.gov/TN/Resources/Nibbles/for_bones.pdf Not that they are particularly better in practice, but at least they are more honest about the nutrition information. If you read the top of the three labels, and what has been circled in red, you see in a word what is wrong with milk. Fat, and lots of it.
Anyone who thinks that milk does a body good should read this;
http://www.rense.com/general26/milk.htm
Yes... milk is Mother Nature's "perfect food" ...for a calf... until it is weaned.
Everything you know about cow's milk and dairy is probably part of a Dairy industry MYTH.
Cow's milk is an unhealthy fluid from diseased animals that contains a wide range of dangerous and disease-causing substances that have a cumulative negative effect on all who consume it.
Here is what the http://www.pcrm.org/health/veginfo/dairy.html has to say about milk.
Milk and dairy products are not necessary in the diet and can, in fact, be harmful to your health. Consume a healthful diet of grains, fruits, vegetables, legumes, and fortified foods including cereals and juices. These nutrient-dense foods can help you meet your calcium, potassium, riboflavin, and vitamin D requirements with ease—and without the health risks.
One can look further, there are a myriad of studies that demonstrate the adverse health effects of milk.

A vegan needs to eat the following things:
-iodine supplement
-nuts
-flaxseed oil
-spinach
-Vitamin B12 supplement
-Vitamin D supplement
The iodine in milk is derived from feed supplements and/or disinfectant residue left on the milking equipment.
No thanks I will get mine from seaweed.
Nuts are fine, I eat those. I use fresh ground flaxseed, not the oil, and spinach I eat all the time.
None of the supplements are necessary or desirable. I am not certain that supplements are even absorbed by the body. I suspect that the largest portion of these so called supplements just get flushed down a urinal.

Simple vegetarianism is easy; replace meat with beans. Going vegan should probably set off a few alarms when you realize you need to research how not to become sick while following a particular diet.
Must say I heartily agree with you about researching what you eat. In fact I think this post is a good example of some of that reseaerch.
I was about 20 - 25lbs overweight, and decided to stop eating meat. I figured, I am going to give up a vital portion of my diet, so I need to research what I need to replace it with. It was as a result of that research that I decided vegan was better, because dairy has even greater side effects than lean meats. As a consequence of my decision, I am now enjoying the best health of my lifetime.
Another person who became vegan after doing some research. T. Colin Campbell, author of "The China Study".
He grew up on a dairy farm and did his college thesis on raising beef more efficiently.
Campbell is a remarkable man, he has been involved in nutrition research at the highest levels for 50 years. He has headed up 70 years (simultaneous research) worth of research funded by the National Institute of Health and other public health institutions. He switched to a whole foods plant based diet 15 or so years ago.
Here is an 11 minute http://www.vegsource.com/articles2/campbell_qa_expo.htm excerpt of a Q&A after one of his presentations.
Here is one of his latest presentations on cancer, the primary field of focus for the research he has done.
