Koffein och animalsikt protein driver kalcium ur kroppen och orsakar därför benskörhet.
Det har uppskattats att för varje gram animalsikt protein skickas 1 mg kalcium ur kroppen med urinen.
"Two factors make animal protein more calcium-costly than plant protein. As mentioned, excessive protein intake leads to greater urinary calcium losses. With excess protein the blood becomes more acidic. To buffer this acid rise the body relies on calcium, which it may leach from the bones. Compounding the problem is the fact that animal protein has more sulfur-containing amino acids which tend to increase calcium losses." http://www.gentlebirth.org/nwnm.org/Diet_Prevents_Osteoporosis.htm
"It has been estimated that for every gram of protein consumed, urinary calcium increases by about 1 mg. The sulfur amino acids appear to be responsible for this effect by increasing the acid load, which then increases calcium loss." http://www.heartlandfields.com/soy_health/bones_1.html
"Animal protein tends to leach calcium from the bones, leading to its excretion in the urine. Animal proteins are high in sulfur-containing amino acids, especially cystine and methionine." http://www.makingpages.org/health/calcium.osteoporosis.html
"Meats are overly high in protein and are high in a particular kind of protein building block, called sulfur- containing amino acids. These cause increased calcium loss.
Caffeine and sodium also increase the rate at which calcium is lost through urine." http://articles.animalconcerns.org/ar-voices/archive/calcium.html
"Loss of calcium from bone is thought to occur because of bone mineral resorption that provides the buffer for the acid produced by the oxidation of the sulfur amino acids of protein (Barzel and Massey, 1998)"

“Greens such as kale, broccoli, and bok choy are as good as milk in terms of their calcium absorbability.” (Environmental Nutrition. January 1994, p. 3. The American Journal of Clinical Nutrition 1990; 656-657)
