Women who drink about five cups of coffee a day more than double their risk of suffering a miscarriage during the first three months of pregnancy, Swedish doctors report. The danger applies to non-smokers, Reuters stated. The researchers said the risk did not rise among smokers, probably because they already face a higher risk ofmiscarriage. Although the findings are tentative, "reducing caffeine intake during early pregnancy may be prudent," said the team, led by Dr. Sven Cnattingius of theKarolinska Institute in Stockholm. Their findings, are based on interviews with 562 women who had miscarried at Uppsala University Hospital and 953 who had not. The team found women who consumed between 100 and 299 milligrams of caffeine per day - the equivalent of one to three cups of coffee - were 30 percent more likely to have a miscarriage during the first three months of pregnancy than women who consumed less than 100 milligrams. The risk was 40 per cent higher among women who drank 300 to 499 milligrams daily and 220 per cent higher for women who consumed 500 milligrams or more. Brewed coffee has about 115 milligrams of caffeine per 4.5-ounce serving. Full findings are published in the recent issue of the New England Journal Of Medicine.
