Cancer and Vitamin D

If I caught your attention with that headline, why not review your supplements right now and add up the total number of units of vitamin D you’re taking every day.

If that number is at least 1,000 IU (international units), hit the DELETE button and move on to your next e-mail. You can do so feeling pretty confident that your nutritional program has been lowering your risk of developing cancers of the breast, colon, and ovary by as much as 50%.

All this was the subject of an interesting article entitled “The Role of Vitamin D in Cancer Prevention,” which appeared in the prestigious American Journal of Public Health and reviewed 63 separate studies conducted over the past 40 years.

The conclusion: public health authorities should urge people to increase their vitamin D consumption.

Vitamin D has been getting more and more positive press lately. Low levels of vitamin D have already been linked to multiple sclerosis, heart disease, diabetes, and high blood pressure. Scientists know that you need vitamin D to increase calcium absorption, control immune function, and reduce your body’s resistance to insulin and thus prevent Type 2 diabetes.

Most vitamin D is made by your body itself, produced by the effect of sunlight on your skin. But if you live in heavily overcast parts of the world with dark autumns and winters–or if you cover up in the sun or stay indoors a lot–you’re definitely at risk for vitamin D deficiency.

It’s for this reason, by the way, that more people develop multiple sclerosis in the darker Scandinavian countries and in Canada than along the equator.

If your supplements are giving you less than 1,000 IU of vitamin D a day and you think you’re getting a lot of D from foods, consider:

  • One cup of vitamin D-fortified milk has barely 100 IU of D–about 10% of my recommendation.
  • One egg yolk: 25 IU of vitamin D.
  • On the other hand, one tablespoon of cod liver oil has more than 1,300 IU of vitamin D.

If you’re interested in taking a supplement, check your local pharmacy or click here for the vitamin D we recommend to our patients. It’s surprisingly inexpensive and really can pay off in positive health rewards.

  • Ten Drugs Doctors Should Consider De-Prescribing

    Physicians use the word polypharmacy when a patient is taking five or more prescription drugs daily. A recent survey showed that half of women Medicare recipients were taking five or more drugs daily, and 12% of them were taking ten (!) or more. New patients frequently arrive at WholeHealth Chicago carrying bags stuffed like piñatas with prescription drugs and nutritional supplements, the latter recommended by Read More

  • Toxic Metals, Heart Disease, and Chelation Therapy

    In last week’s Health Tip I reviewed the well-researched health dangers of environmental toxic metals (also called heavy metals). They’ve always been a serious health risk, but with the Trump Administration’s recent rollbacks of clean air and water regulations we can expect even more trouble ahead. Statisticians predict an astonishing 160,000 unnecessary deaths over the next decade from the reversals of clean air and water Read More

  • Heavy Metal Toxicity and Your Health

    For those who were otherwise preoccupied that day long ago in high school chemistry, the heavy metals refer to a group of especially dense metals or metal-like substances (called metalloids) found in the environment. These metals–specifically lead, mercury, arsenic, cadmium, and aluminum–can all be absorbed by your body and stored there. Our environment is already quite toxic (Trump’s EPA deregulations aren’t helping) and it’s getting Read More
