The following is from a newsletter, I received. I've been going back and forth about going raw or at least vegan, and got this in my mail today. I'd like any opinions your group can offer. Thanks!

If you've read anything about the vegetarian diet, you may already know that it is deficient in nutrients like B12, vitamin A, vitamin D and weak in zinc. But why does it matter?

Vitamin B12 deficiency is one of the chief causes of fatigue. You know all those energy drinks you see in the store? Pick one up and check the label ingredients for B12 - you'll often find it listed. The body absolutely requires B12 for normal cell activity, and it works along with folic acid to control the level of homocysteine (a building block of protein) in your body. An excess of homocysteine increases your risk of heart disease and stroke, two of the premier causes of death in this country. B12 does not exist in the plant world. There are look-a-likes (analogues) but not the real thing. These analogues actually interfere and cause us to need even more of this vital nutrient. B12 is found in dairy, meat, eggs and poultry.

Vitamin A deficiency weakens your immune system. It is an antioxidant, it develops your bones and the enamel in your teeth, and it stimulates stomach acid for proper digestion. Vitamin A sources include butterfat, egg yolks, organ meats, seafood, and the ever popular (of late) cod liver oil.

Vitamin D deficiency causes illness - particularly colds and flu. It also causes muscular weakness. It aids in the absorption of calcium and protects and maintains your bones. Vitamin D sources include sunlight, fish, liver, eggs, chese and cod liver oil (another health industry "buzz word" of late).

Zinc deficiency causes infertility and reduced libido in men, an upset menstrual cycle in women, hair loss, frequent infections, reduced ability to see in the dark, poor appetite and mental fatigue. A trace mineral, it is second only to iron in the body. It is essential for the proper functioning of your immune system. Zinc sources include beef, pork, chicken, fish, oysters and lamb. High levels of copper in soy and many vegetable foods antagonize zinc in the body.

Because deficiencies can take decades to fully develop, the proportions of vegans and vegetarians who develop nutritional deficiencies over time (if they stick with the diet) is likely close to 100 percent.

2. The average lifespan of a vegetarian is not what you might think.

Overall, vegetarians die of slightly less heart attacks, but they do not have as long a lifespan as non-vegetarians. In terms of disease, it is widely known that obesity and diabetes both rank right up there with heart disease and cancer in terms of the leading causes of death. What you probably don't know is what all these things have in common - insulin and inflammation.

You may have heard that inflammation causes heart attacks. A lesser known fact is that high insulin causes inflammation...which causes the disease. High insulin is caused by excessive carbohydrate consumption. Given that vegans and vegetarians eat mainly fruits and vegetables, one of the biggest struggles is avoiding the over-consumption of carbohydrates. This is paramount to controlling insulin, and therefore, disease.

3. If history says anything, there is proof.

There have been healthy societies that only ate animal foods, but we have NO records of a healthy vegetarian society that did not fall prey to modern diseases. India and China have been touted as healthy vegetarian societies (made famous by another well-marketed book - "The China Study"). What has not been fully explained is that both countries were really forced into being vegetarians by poverty and starvation.

In Oriental Medical School, we only learned about treating malnutrition. Our Chinese professors had nothing to say about weight loss. It had never been a major problem in China. Drs. Royal Lee and Weston A. Price were huge researchers in the field of nutrition, probably the best the U.S. has ever produced. They both were vegetarian and studied cultures from around the world looking for healthy people with straight teeth and superior resistance to disease. Only a handful of cultures met this criteria in the 1930's and none of them were vegetarian. Drs. Lee and Price found that weak patients could not be brought back to health without using animal sources for nutrition. After traveling across six continents, Dr. Price stated that his biggest disappointment in life was that he never found a healthy vegetarian society.

I've tracked my diet on fitday. The only nutrients that I am not getting from my food are Vit. D and B12. For now I am supplementing those two until I feel more certain that I am getting enough Vit. D from the sun. B12 I will likely always supplement.

Zinc and Vit. A I get plenty of.

Do you realize that Dr Price is an Atkins advocate and probably funded by the meat and dairy industries? Oh and Dr Price also thinks people should eat more animal saturated fats, butter and bacon are perfectly healthy and even beneficial to health...

Vitamin A from animal sources?! The best best source of vitamin A is from vegetables.

Vitamin B12 is found in the plant world, every mammal at least needs vitamin B12 which includes herbivores. Humans may not get vitamin b12 because they rid their foods of the bacteria that gives you b12. Only person I've known to be b12 deficient was actually a meat eater.

Vitamin D does come naturally from the sun and from fish. In dairy, vitamin D is added. I've heard of Vitamin D deficiencies in places like Scotland where they get very little sun but otherwise it is a rare deficiency.

The China Study does go over the fact that people are vegetarian due to poverty and calls things like diabetes and cancer 'diseases of the affluent'. What does it matter if people are vegetarian because of poverty? They are fairly disease free at least for diseases common in the west.

Also studies have shown vegetarians live longer than omnivores although some vegetarians still consume lots of animal products and those that don't live even longer.

Article is a bunch of hooey.

I suggest that you read The China Study. Most studies are biased towards whoever financed them. The China Study tells it as it is.

Hey Matt -

where do you get zinc from? How about selenium? Those are my areas to improve on...

pumpkin seeds are a great source of zinc as well as other nuts/seeds. Sprouted legumes would also provide you with zinc. Selenium generally comes from nuts, Brazil nuts are particularly high in selenium.

I'd have to look through my log and see what are the individual sources. If I find that anything I've eaten is a really great source though I'll be sure to let you know.

Guyz??? Yoo Hoo? Think this might be where you could find it...?

an example of what I ate yesterday and the nutritional results for it. I left out my supplements, which I usually track because my B-12 I get from a multivitamin until I finish the bottle and I didn't want to obscure my results.

VFL, thanks for pointing out Nellie's helpful post--I *do* eat a lot of nuts so that is probably where I'm getting them. I think that I recall tahini being a really great source as well.

I read ,in the rules for posting,when I was looking at the kinds of posts that are acceptable,that we dont come here for justifying or defending the raw diet.We dont need to.This site ,as I understood it,is to inspire and encourage and support those who want this way of eating?
If you want to find out these things,there are a ton of sources to seek assistance for the questions. Then when you are satisfied, you can decide what you want to eat.Love it that we can choose!!!
We are on this site and here if you decide raw and want support.The very best to you in your search.

Well....as far as B12, they are wrong to single out any one group as it can be anyone, not just vegans. You can easily supplement though. Found this for you:

SYDNEY, AUSTRALIA. It is generally assumed that vitamin B12 deficiencies are rare among people consuming a varied diet. However, there is some question whether vegetarians get enough B12 as it is not present in plants. Researchers at the Sydney Adventist Hospital have just completed a study aimed at resolving this question. Their study involved 245 Adventist ministers who were either lactoovovegetarians or vegans. The average age of the ministers was 46 years (range 22 to 80 years) and most of them had been vegetarians for over 20 years. The study participants filled out a diet questionnaire and had a fasting blood sample drawn for a 20-test biochemical profile including vitamin B12 concentrations. The mean vitamin B12 level was 199 pmol/L and 73 per cent of the ministers had a level below the recommended lower limit of 221 pmol/L. Vitamin B12 concentrations were also measured in a control group of 53 ministers who consumed fish, poultry or red meat on a regular basis. In this group 40 per cent had vitamin B12 concentrations below the recommended lower limit; this indicates that vitamin B12 deficiency is widespread even among non-vegetarians.

Additional tests showed that the vitamin B12 deficiencies observed among lactoovovegetarians were due to dietary deficiencies rather than to malabsorption. The researchers conclude that as many as 73 per cent of Australian vegetarians are vitamin B12 deficient and recommend that they increase their intake either from vitamin B12-containing foods (animal products), from supplements or from vitamin B12- fortified foods.
Hokin, Bevan D. and Butler, Terry. Cyanocobalamin (vitamin B-12) status in Seventh-day Adventist ministers in Australia. American Journal of Clinical Nutrition, Vol. 70, September 1999, pp. 576S- 78S


I can't find anything about deficiencies taking decades to show up...years? Yes, no mention of decades though! LOL!

Do vegans/vegetarians live longer? the vast majority of studies done say YES.

An excellent article: This section is from the book "The Hygienic System: Orthotrophy", by Herbert M. Shelton. http://chestofbooks.com/health/natural-cure/The-Hygienic-System-Orthotrophy/Fruitarianism-And-Vegetarianism-Continued.html

http://howtolosebelly.com/2008/10/is-the-vegetarian-diet-healthy/

Now, to balance things, there is this article which states that there can in fact be a shortening of lifespan in vegans...however, once more, the belief is that it is due to elevated homocysteine levels because of low B12. So we're back to supplement your B12!

Being vegetarian, vegan, raw or raw-vegan isn't the issue as far as lifespan, but more that you need to be aware of what your body needs and where to find those nutrients (and really, that goes for whatever style of eating you follow). Learning about food combing is a good idea as well.
