More calcium intake needed to support protein intake?

[enwar3]

The human body uses calcium reserves to digest protein. So when you eat meat or drink milk, your body is actually pulling calcium out of storage and utilizing it to help digest protein. One study suggested that for every 50mg of protein consumed, 60mg of calcium is used.

The article is about the affects of milk on your body, including calcium, protein, and magnesium intake. The fact I found interesting was that you need over a 1:1 ratio between calcium intake and protein intake. Most of us are eating 1-1.5g of protein per pound of bodyweight a day. Does this mean we should be eating even more calcium?

Note also that other studies quoted in the article show no bone loss as a result of protein digestion.

Don't believe everything you read. You know the RDA for calcium is the equivalent of 1g of protein? So you're asking if we should be taking 150X the RDA to equal our protein intake? A big fat "hell no" to this one. Unless you want this to happen to you:

Symptoms are more common at high calcium blood values (12.0 mg/dL or 3 mmol/l). Severe hypercalcemia (above 15-16 mg/dL or 3.75-4 mmol/l) is considered a medical emergency: at these levels, coma and cardiac arrest can result.

I'd take that article with a grain of salt. Actually make that an entire saltshaker's worth.

That article is retarded it says avoid milk because it pulls calcium out because of its protein content. Does that mean you should avoid protein like meat because it will extract calcium from you as well?

They make it sound like extra protein is bad for you. By that logic anything that contains protein and not a larger amount of calcium is bad for you.

First of all, why wouldn't the calcium be able to be reabsorbed? Secondly, 1:1 ratio? Are they sure they didn't mean 60mg of Ca to every 50g of protein? That's insane otherwise. No doctor would recommend such a large dose of calcium. Also, it doesn't seem to take into account that Ca is actually in the milk... Shouldn't that blunt the extraction of Ca from bones?

Also, I've read research articles that state lifetime high levels of calcium is actually detrimental to bone health. I read through the journals and was a bit confused, but it made some sense when it referred to mechanisms. It linked high levels of calcium to osteoporosis and other bone diseases as well.
