Yes. Weight-bearing activities increase bone density. I don't know how much it helps at the age when you're most likely to develop osteoporosis (since you most likely will have cut back by then), but I don't see how it can hurt.

There is evidence that one course of Fosamax (or drugs in its class--the bisphosphonates) does it for a long long time.

First the study that reducing fatty foods not lower a woman's cancer risk and now this:

I didn't know this was Truth In Health Sciences Month.

The problem I have with an announcement like this is that it is generally recognized that most folks are actually deficient in calcium.

We used to drimk well water and water flowing in streams, in most places in the country, positively loaded with calcium.
Now, in a lot of areas, we are drinking water that has far less than it used to.

Remember, if you fractionalize the body into elements, besides for carbon and water, calcium is by far the most prevalent element.

I wonder who funded the study and what form of vitamin D they were using.

Yep--moving around as much as you can even if you're 90 years old is the best thing for every system you have. I have a 91 year old uncle (I'm going to visit him in a few weeks with my son) and he still moves pretty good when he mixes up a batch of martinis for the three of us. No foolin'...

There's an old saying, "For every child, a tooth" - a tooth lost that is. I got so many cavities during or right after my pregnancies it wasn't funny.

Supported by the National Heart, Lung, and Blood Institute and the General Clinical Research Center program of the National Center for Research Resources, Department of Health and Human Services. The active study drug and placebo were supplied by GlaxoSmithKline Consumer Healthcare (Pittsburgh).

Methods We recruited 36,282 postmenopausal women, 50 to 79 years of age, who were already enrolled in a Women's Health Initiative (WHI) clinical trial. We randomly assigned participants to receive 1000 mg of elemental calcium as calcium carbonate with 400 IU of vitamin D3 daily or placebo. Fractures were ascertained for an average follow-up period of 7.0 years. Bone density was measured at three WHI centers.

"I once read a study that suggested that calcium supplements cause your blood calcium to rise, and so your body says "uh-oh too much calcium!", and then proceeds to remove it... mainly by removing it from your bones, thus having the exact opposite effect that you wanted."

Calcium initiates muscle contraction. In other words, when muscles contract they burn calcium. The body under a normal daily activity burns approximately 900 mg. If we don't supply at least 900 mg. per day through our diet then we are in a negative calcium balance. That means we still use our muscles but it isn't available so our muscles will have a tendency to go into spasm. Then over a period of years the body goes to where it is stored (bones) and pulls it out and takes it through the muscles to use which eventually leads to a demineralization of the bones or osteoporosis. Calcium, in the body, is regulated by the parathyroid gland.

The amount of calcium we take isn't as important as the amount we absorb. If the body doesn't absorb it then it is washed out of the system. Important factors in it's absorption are Vit D, exercise, and Phosphorus. Vit D and exercise both increase absorption while Phosphorus decreases it.

The lack of calcium and minerals in our diet is to blame, due to petroleum based fertilizers. You cannot escape this conclusion, if you know anything about soil. Even if you make meals from scratch, you still are working with mineral depleted vegetables and meats.
Ubiquitous corn syrup is also a health danger, and subsidies of US cane sugar growers must stop, so we can once again have affordable cane sugar in food and drinks and stop the obesity epidemic.
I know, I'm probably going to be labeled as a crazy. I scoff at Global Warming, but think the soil issue is serious, and so is the fructose issue.

Well, I agree with you that fructose is slow poison...no question about that.

Old women often don't fall and "break a hip"....what happens is a bone BREAKS, causing them to fall....and yes, ACTIVITY does help.

Uhhh...calcium is not "burned" when it is used in muscle contractions. It is eliminated in the urine and absorbed through the gut. And you have forgotten to mention the very potent parathyroid hormone in calcium and phosphorus metabolism.

This pertained to the upregulation of whatever enzymatic pathway builds or removes bone structure... Put another way, the skeleton represents a large reserve of calcium, and keeping blood concentration precisely balanced is a strong priority over how much the bones get to keep for themselves.

My doc recently told me to substantially increase my Vitamin D intake....that it was MORE important than Calcium...so, I'm up to about 2000mg/iu? a day. (Something in a blood test said I was losing bone at a faster rate than I should.) People in the northern states should probably ALL be taking more. And, Calcium IS overrated....I always hated milk, but I probably have stronger bones than 80% of women in my age group (nearly 55).

Yep....I tell my ladies strength training class that all the time. The youngest participant is 51...the oldest 76. You should see them do what they never thought they'd be able to do when they started. I never have them on any machines. They use all free weights, stability balls and bodyweight.

I have a nextdoor neighbor, who has osteo arthritis. She has lost 3 vertebraes in her back. She will be in a wheelchair shortly, and has Macular Degeneration. The Back problem has caused her to shrink more than 3".

It is sad to see her wither away to nothing.

Getting old is never pretty. she is 78 years old this year, and cared for her husband when he came down sick and died, mourned for years, now she has lost her sight and her bones are giving out on her.

I want to be like a dear friend of mine who passed away last october.

She was 93. Drove until Friday, died Saturday, and buried the following Wednesday. Had pain, from arthritis, but she was capable of getting around til she just was not there any more

I'm taking My Calcium, Magnesium, and D. FOREVER.

Perhaps 'burned', being a lay term, wasn't a good choice of words. Calciuim ions in the sarcoplasmic reticulum are used to initiate muscle contraction. There, is that better? And I did mention the parathyroid glands.

Could you explain this, please.

I wonder who funded the study and what form of vitamin D they were using.

Good Q and also, what form of calcium was used for the study. Many common forms used in supplements is anot al that easily assimilated, and thats what counts, by the body. Cal carbonate is most common - and is very hard for the body to assimilate. D helps with its use by the body, but still only a small % is actually going into the bloodstream.
Calcium citrate is probably the best form for humans. It should be accompanied by Vit D, and some Zinc for best use by the human system...;-)!
