The Calcium Myth

posted by Mel, selected from Natural Solutions magazine Sep 28, 2009 5:01 pm

By Michael Castleman, Natural Solutions

We’ve been told all our lives to drink milk for strong bones. Many of us even feel guilty when we don’t get the recommended three servings of dairy each day. In fact, we’ve been led to believe that we have a “calcium crisis” in the United States because so many of us don’t get enough dairy. The proposed solution? Drink more milk, eat more yogurt and cheese, and take calcium supplements.

So why are we convinced that milk, dairy foods, and calcium supplements prevent the fractures osteoporosis can cause? Because teachers, doctors, and advertisers have told us we need calcium–and lots of it–to keep our bones strong as we age. Because every major US health agency endorses daily consumption of milk and dairy: the Surgeon General, the Centers for Disease Control and Prevention, the National Institutes of Health, and the National Osteoporosis Foundation.

But consider this: The most industrially advanced countries–the US, Australia, New Zealand, and most Western European nations have the highest fracture rates–yet consume more dairy than anywhere else in the world. Meanwhile, the people in much of Asia and Africa consume little or no milk (after weaning), few dairy foods, and next to no calcium supplements, and their fracture rates are 50 to 70 percent lower than ours. What’s going on?

The latest research shows that our bones need more than just calcium. It turns out the way we eat–along with our lifestyle choices and stress levels–can actually contribute to bone depletion, no matter how many calcium supplements we take or glasses of milk we drink. Amy Lanou, PhD, an assistant professor of health and wellness at the University of North Carolina Asheville, and I came to this realization after reviewing 1,200 studies on the dietary risk factors for osteoporosis. Our rather radical conclusion: The calcium theory is bankrupt. The better solution? Eating a low-acid diet, which strengthens bones much more effectively and, as a growing number of bone-health researchers agree, holds the key to preventing osteoporosis.

:D i'm going to show this to my mom so she'll finally get off my case with the whole "you'll die if you don't drink milk!" thing.

Sorry,here is the source:

Thewre are many ways of losing calcium-breathing is one of many.

If you read my previous answers, I referred to balance-milk is not a preferred source for calcium that it has been made out to be-please, read my answers on this same article. Our bodies are not made to process even human milk as adults, much less another animals with different composition, nutritive, and immuno values.v

Lisa B.

I am sorry Clyde but I am confused. You have said that a can of soda causes the body to withdraw 20mg of bone calcium. The opinion piece didn't say that. The links you gave didn't say that either. So where is your source?

And now you are agreeing that your body balances blood pH by breathing? So the reason for not drinking milk is because there are better sources of calcium? Is that what you are saying?

Clyde N.

Lisa, visit the links I gave-the calcium-osteoporosis lnk is dicussed in the care 2 article. Milk is not that great of a source of calcium-read the naturescorner article-about 30% of the calcium in milk is available to the body while about 70% from vegetables is available to the body.Yes, deeper and/or faster expels the carbon dioxide(C02), which is carried in the blood as carbonic acid, driving down CO2 loweres the carbonic acid in the blood, driving up the pH-the blood pH becomes more alkaline.High alkalinity can be fatal as can high acidity-without underlieing medical causes, it would be very hard to achieve fatal levels.

Lisa B.

All of this discussion fails to mention that the act of breathing maintains the acid-base balance in your blood.

Clyde, you say the body must withdraw 20mg of bone calcium for every can of coke, and 10mg of calcium for every gram of meat to neutralize the acid that is the byproduct of the digestion of meat. Pretty bold statements. What are you basing these statements on?

And isn't this discussion about dairy? One of the articles you quoted doesn't even mention dairy.

Again, I say this is a poorly researched article, and the comments are hardly convincing me otherwise.

I didn't know Dr. Oz recommends dairy. Anyone who would roll up his sleeve on national television to get a flu shot is seriously misleading the public. The pharmaceutical company's own research proves vaccines are dangerous. It also proves that Dr. Oz hasn't bothered to read anything. I guess celebrities will be believed no matter how educated or uneducated they are.

I've never liked Dr. Oz and the flu shot was the final nail in the coffin for me. It's just too bad that there are so many gullible people who believe and trust him.

Mariaanne Hale, there already is plenty of research-American diets are high in acids(sodas,SOME, not all,juices(surprisingly,most citrus fruits do NOT qualify), proteins) which leach calcium out of our bones to maintain the blood's alkaline pH-this causes osteoporosis and bone spurs. The pH levels of your mouth is between 6.2 and 7.0. However, immediately following fermentable carbohydrate (sugars) consumption, pH values drop significantly. The average pH required for enamel demineralization is 4.5 to 5.5. A can of soda has approximately a pH level of between 2.7 and 3.5. Once the oral pH has lowered, without brushing or rinsing, it takes 1 to 2 hours to recover and return to normal.

The blood MUST maintain this ph and will withdraw calcium from the bones to neutralize blood ph that is too acid. For every can of soda that is drank, the body must withdraw 20mg of bone calcium to neutralize the acid, and for every gram of meat ingested, 10mg of calcium is utilized to neutralize the acid that is the byproduct of the digestion of meat.

Here some excellent articles and charts:

Someone needs to tell Drs. Oz and Roizen about dairy not being so great as they claim. Americans consume more calcium than any other nation and we have the highest rate of bone fractures, osteoporosis. Why don't they do the research or are they brainwashed by the dairy association?

Jeanne Brady

The information in this article is not news; I was reading about this 20 years ago when I made the decision to quit meat-eating.

One thing that is missing, though, is the importance of exercise to bone health. Bones are actually a lot like muscles in that stressing them forces the body to strengthen them (and not stressing them causes them to weaken).

Most of the cultures who consume little dairy and have low rates of osteoporosis also largely get around by walking or biking, not driving cars.

Diet is important when considering bone health, but exercise is at least equally so.
