question about calcium
Just wondering if about calcium. I always see calcium supplements advertised and suggested to women "of a certain age", and I am just wondering when it really would be appropriate to start taking them. As a low carber who takes a multi vitamin, but drinks no milk and eats very little dairy, would I need the extra calcium in a supplement? Maybe a better question would be, could it hurt to take it?

calcium is a large element - so if you look carefully at your multi-vitamin, the recommended daily percentage listed is probably about 10%... i take a calcium supplement although i'm now starting to try getting into the habit of taking it daily. it doesn't hurt to take (i'm pretty sure about that..)

Good question, but I don't know thw answer. I take a cal/mag/K supplement and have been doing it for years without questioning it. I think I've been more afraid of breaking my hip than heart disease. :eek: Dairy products are not exactly the best source of calcium. Magnesium has to be present for it ot be effective
There was a comment on it by Mrs. Yogi today. She takes it before bed, says it helps her sleep. I've read that it helps prevent teeth grinding while sleeping if you take it before bed. There's also other reasons it's good to take, but I can't remember them! Karen |

You are never to young to start calcium if your diet is inadequate. I suppliment my kids' diet with orange juice plus calcium. Exercise is one of the best things you can do for your bones.
My 50ish year old sister has bone cancer and she is a marathon walker. The doctors have told her that the walking has prolonged her life and her density is that of a 30 yr old, even though she has cancer! |
calcium
agreed, yup, yessir, mm-hmmm ... Calcium good.
Current RDA's for calcium are -
Dairy products are indeed rich in calcium, but it's not very well absorbed. In particular, the casein protein inhibits absorption. (interesting note - casein from cow's milk is widely used in industry and manufacturing ... its glue-y properties have many uses in house paint and construction materials ;)). I still love my cheese and yogurt, but I don't rely on dairy for my calcium supply. Here's a quote from an article from Physician's Committee for Responsible Medicine - Quote:
Another important factor for calciium absorption is Vitamin D. The body can manufacture its own Vit. D in the skin, from exposure to sunlight. For those of us in the north country that means in winter especially, we need to supplement vitamin D. In North America, liquid milk products are fortified with vitamin D, but cream, cheese, yogurt, ice cream etc ... are not. hope this is helpful, Doreen |
Is it true that too much protein (supposedly what the West typically consumes) causes acidity in the body to the point where calcium is leached out of bones in order to stabilize that blood acidity - resulting in osteoporosis even with the increased dairy intake, which is why in underdeveloped countries/or cultures who don't consume hardly any dairy products/meat products do not get osteoporosis etc...

hi bluu
The answer is NO.
From Protein Power .. http://eatprotein.com/ .. Quote:
As well, high-cellulose insoluble fiber, as found in grains, bran etc is well-known to inhibit the absorption of dietary calcium, therefore the calcium is excreted from the body, not absorbed. Consuming adequate protein and fats, as well as the foods listed which are good sources of absorbable calcium ... and ensuring a supply of vitamin D, whether from natural sunlight or supplement .. is your best insurance for healthy bones. As well, weight-bearing exercise, such as walking has been shown to increase bone-density by up to 10% .. :) Doreen |
