High intake of calclium boosts risk of prostate cancer, according to a recent study. Researchers examined 783 African-American men of whom 533 were diagnosed with prostate cancer. Men who reported the highest intake of calcium were twice as likely to suffer prostate cancer, compared with those who reported the lowest intake.
Additionally, men with a genotype linked to poor calcium absorption were 59 percent less likely to be diagnosed with advanced prostate cancer than those with a genotype linked to high calcium absorption.
Calcium is high in dairy products and some vegetables including pinto beans, red beans, white beans, bok choy, kale, broccoli, and spinach. However, eating calcium-rich vegetables has not been associated with increased risk of cancer, while high intake of dairy products has. Researchers at Oxford University reported that high intake of protein from dairy products produces high serum levels of insulin-like growth factors or IGF-1, linked with risk for both prostate cancer in men and breast cancer in women.
