Try it Again, Dr. Kim!
Dr. Kim is a chiropractor who runs a fasting clinic in Ontario, Canada. This was the post by Dr. Kim that Mr. Norris was discussing in his blog:
More Thoughts on Earthlings Documentary, Including Potential Problems with a Strict Vegan Diet
Dr. Kim was a strict vegan for 4 years, but he says:
"I only felt like I was optimally supporting my health for the first two of those years. The last two years were marked by low energy, constant cravings for some animal foods, skin breakouts, and emotional lows that I had never previously experienced."This is what he ate for 4 years:
"My strict vegan diet consisted of plenty of fresh leafy greens, tomatoes, bell peppers, cucumbers, celery, sprouts, many varieties of steamed greens, steamed root vegetables like potatoes, sweet potatoes, hard squashes, carrots, and red beets, whole grains like brown rice and quinoa, a wide variety of fruits (including avocados), legumes like chickpeas and red beans, and small amounts of raw nuts and seeds. I also drank fresh lettuce-based vegetable juices a few times a week."Mr. Norris says that Dr. Kim probably wasn't getting enough vitamin B12:
"Obviously, if a vegan is not taking B12 supplements or eating fortified foods, for more than two years, chances are excellent they are going to get fatigued and have mental issues."He also says he probably lacked adequate protein:
"If you read Dr. Kim’s description of his diet you have to get well into his list before you come across a plentiful source of protein (quinoa), and the most reliable sources that most vegans rely on, even raw foodists, are listed second to last and last!"So, both Jack Norris and Dr. Kim state that vegan diets fail to provide adequate vitamin B12. Mr. Norris says that vegans need to be attentive to consuming higher protein plant foods. Dr. Kim says vegans risk deficiencies in the longer-chain omega-3 fatty acids DHA and EPA, in vitamin A (not the plant-based carotenoid precursors), cholesterol and saturated fats (although our body makes these from plant food, he says not enough are made), and several minerals including zinc, iron, and calcium.
I think B12 and minerals are a problem. I still don't know about protein, longer-chain omega-3s, saturated fat, and vitamin A. Although, it's true that animal foods are good sources for these.
