Calcium intake and prostate cancer risk
I have mentioned the possible risk of prostate cancer due to increased calcium intake in the 7th Newsletter and the 9th Newsletter. The research implicating calcium as a risk of prostate was done by one research group. A recent study done at Johns Hopkins, PMID: 12475694, was unable to find a correlation between increased calcium intake and prostate cancer. Additionally, they found no association between intake of phosphorus, vitamin D, fructose, animal protein, or dairy products and prostate cancer either. These results mirror those of an Italian case-control study, PMID: 11433421, done in 2001 that found no relationship between calcium intake and prostate cancer risk. A 1999 study in the The Netherlands was also unable to correlate calcium intake with prostate cancer, see PMID: 10362125. These are reassuring results and they indicate that until controlled clinical trials are ever done that truly test the effects of high calcium intake on prostate cancer risk, there are probably other issues of greater concern to men with osteoporosis.
