Too much Vitamin D increases heart attacks, arthritis and degenerative joint disease (1980)

Too much vitamin D -- possibly at levels just above the recommended 400 IU's per day -- may increase heart attacks, arthritis and degenerative joint disease according to a wonderful book published in 1980 called "Sunlight Could Save Your Life" by Zane Kime, MD.
Currently, in 2012 and for the past several years, vitamin D has been heralded as a miracle nutrient, and many, many, many doctors and researchers are recommending that people take a vitamin D supplement.
Some recommend taking 1000 IU’s per day.
Others recommend taking 2000 IU’s per day.
Some others have recommended taking 4000, 5000, and even 8000 IU’s per day.
However, this might be a huge mistake based on what Dr. Kime wrote in his book about Sunlight back in 1980.
I have not gone back to look at the research that Dr. Kime wrote about, some of which goes back to 1935.
And I don’t know if perhaps the type of vitamin D they were using 30 and 40 and 70 years ago was somehow different than the vitamin D3 they recommend today.
I am writing about this to encourage somebody to go back and look at the old research to make sure we are not making a huge mistake by recommending that people take large doses of vitamin D.
Below is exactly what Dr. Kime wrote on pages 148-151 in his book.
Dr. Kim’s Book on Sunlight: p. 148, Vitamin D added to foods
Vitamin D is added to many foods
Vitamin D is also added to baby foods, imitation dairy products, beverages, sweet sauces, prepared breakfast cereals, margarine, macaroni, noodles, farina, and flour (3).
Most store bread has 250-750 IU/lbs added.
With all this supplementation, the average per capita intake is 2435 IU/day, or six times the recommended 400 IU/day.
The examination of human muscle tissue has revealed that human tissue may now contain more vitamin D than was found in the tissue of swine fed 14 times the National Research requirements (4).
Effects of consuming this hormone
From the University of Tromso in Norway comes a report that a long-term intake of vitamin D, only slightly above the 400 IU recommended, may stimulate myocardial infarction, or heart attack.
Not only heart attacks but also degenerative joint diseases and arthritis are mentioned in the report, as diseases that are apparently promoted by an increased vitamin D intake (5).
Dr. Mildred S. Seelig, a physician in charge of nutrition and metabolism at New York University’s Goldwater Memorial Hospital, and associate professor of pharmacology at New York Medical College, has spent nearly a decade developing the theory that heart attacks are triggered by the loss of magnesium from the heart tissue.
She points out that excessive vitamin D causes a magnesium deficiency in the heart.
Dietary vitamin D has been known for some time to cause heart attacks in experimental animals, attacks that are completely indistinguishable from those caused by a magnesium deficiency.
Rats that are fed five times as much magnesium as they would normally obtain from their diet are protected from the heart attacks caused by the high intake of vitamin D (5).
When research scientists compared diets and cholesterol levels of 100 farmers, they found that those who were taking additional vitamin D had significantly higher blood cholesterol levels than those who never took the vitamin.
The investigator who reported this study advised “adults not to take vitamin D-containing drugs without a clear reason” (6).
Vitamin D has been identified as an angiotoxic substance (a substance that irritates the lining of blood vessels).
Recently, a group of scientists investigated the effects of vitamin D-supplemented feed on the arteries of experimental animals.
When damaged arteries from the experimental animals were compared with atherosclerotic human arteries (obtained from bypass surgery), damages seen in human and animal arteries seemed identical, even though a number of the animals were on a low-fat, low cholesterol diet.
The exact role which vitamin D plays in damaging the artery wall is not known and is still under study, but the change that does take place is definitely a step in the development of atherosclerosis (7).
A 62-year-old female patient was surprised when I told her that x-rays showed large areas of calcification in some of her major arteries.
She informed me that she had always taken the best care of her body and used very little food that contained cholesterol.
She had always purposely chosen polyunsaturated fats thinking they were preferred and had taken lots of vitamins. [Unwise.]
I asked her about vitamin D, and she assured me that she always took extra vitamin D in the form of a natural vitamin A and D capsule as well as in a multiple vitamin tablet.
Taking into consideration our supplemented food supply, I estimated that for years she had been getting dietary vitamin D in amounts between 4,000 to 5,000 IU’s day.
It is interesting to note that rats, when given vitamin D in the amount of 250 IU’s / day, develop hardening of the arteries and elevated levels of cholesterol and calcium.
They also age fairly rapidly (6).
There are particular problems associated with vitamin D and pregnancy, for pregnant women already subjected to high doses of vitamin D from widely supplemented foods are routinely advised by their obstetricians to supplement their diets with vitamin D pills.
Since vitamin capsules contain 400 IU, if one per day is prescribed, this adds to the already dangerous average per capita intake of 2435 IU/day.
Dietary intake of vitamin D by pregnant women has been implicated in kidney calcification and severe mental retardation in their offspring (8).
Children born to mothers taking extra vitamin D in their diet may be born with a certain type of congenital heart disease called supravalvular aortic stenosis (9).
These same children may show abnormal bone formations and have faces so abnormally shaped that physicians call them"elfin faces” (10).
Abnormalities of the bones of the face have been observed in 70% of the offspring of rabbits given large amounts of vitamin D during pregnancy (9).
Adding a potentially toxic hormone like vitamin D to milk creates more problems than if it were taken alone, for in our society many people consume large quantities of milk.
Milk also has the peculiar property of enhancing the potency of vitamin D.
This was shown over 40 years ago in experimental treatment of children who were deficient in vitamin D. [The book was published 32 years ago in 1980, so this goes back more than 70 years.]
It was seen that the effects of adding only 90 units of vitamin D to each child’s milk were greater than the effects seen when adding, to each child’s diet, 900 units of vitamin D in cod liver oil (11).
Many authorities have recommended that vitamin D be removed from our food.
Dr. Linden, who gave the report from the University of Tromso, makes this statement: “Attempts should be made to restrict the intake of vitamin D from all sources, save that produced by sunlighting the skin”.
Also recommending that vitamin D not be supplementally added to food is the British Medical Association (1950), the Canadian Bulletin on Nutrition (1953), and the American Academy ofPediatrics (1963, 1965).
The Committee on Nutrition of the American Academy of Pediatrics has recommended that non-supplemented milk be available.
