Health Issue: Drink More Milk Can prostate cancer risk

'Drinking too much milk ups prostate cancer risk' London: Excessive milk consumption can increase the risk of prostate cancer, researchers have found.          A Canadian research, published in the Prostate journal, found that men who drank four 200ml glasses of milk had double the risk of the disease, reports dailymail.co.uk. Milk contains cow hormones, including insulin-like Growth Factor 1 (IGF-1). These encourage growth and may help to feed prostate cancer and perhaps, to a leasser extent, ovarian cancer.          ...but no danger from coffee: Men can enjoy a cup of coffee without worrying about prostate cancer as experts from South Korea's National Cancer Center found in a meta-study of 12 previous research that coffee doesn't raise the risk of cancer of the gland.          Experts from University Colege London have suggested that a few thousand years ago people avoided milk because it led to gastric pain and upset stomachs. This is because Europeans loacked the gene to produce the enzyme lactase, which breaks down the milk sugar lactose.          However, Walter Willett, chairman of nutrition at the Harvard School of Public Health, says that "many studies have shown a link between high milk intake and risk of metastatic prostate cancer, explained by the fact that high intake increases blood levels of the IGF-1 growth-promoting hormone"
