Drinking one cup of coffee a day can effectively prevent ovarian cancer and heart disease; two cups a day, pregnant women are twice as likely to miscarry as published in the January 2008 medical journal Obstetrics and Gynecology: of the 1063 adult women interviewed from 1996 to 1998, 172 had miscarriages. the common characteristic of these people is that they use coffee as a drink. If you consume more than 200 milliliters of caffeine a day (about 65 milliliters of caffeine in a cup of instant coffee and 90 milliliters in a cup of ground coffee), pregnant women are twice as likely to miscarry. Professor Shirley Tao Jung of Harvard Medical School, in conjunction with researchers at the University of Utah, conducted a detailed analysis of health samples of 121000 women aged 30 to 35 around the world, and released the results on January 22nd, saying that drinking one cup of coffee a day can significantly reduce women's risk of developing ovarian cancer. Coffee: from relieving fatigue to curing Diseases since the discovery of coffee by the legendary Ethiopian shepherds in the 6th century AD, people have been used to relieving fatigue with coffee. Up to now, people with a little common sense know that coffee can relieve fatigue for only two hours, and then they will feel more sleepy.

In November 2006, German scientists specifically rectified the preventive and therapeutic effects of coffee on some diseases, proving that coffee drinking is not directly related to the prevention of diabetes and kidney cancer, and dispelling rumors that drinking coffee can lead to dehydration. But coffee does help to prevent some diseases. Scientists at Bregan Women's Hospital and the Harvard School of Public Health showed that drinking coffee regularly did not cause high blood pressure by tracking 155594 women who took part in health examinations. researchers at the University of Iowa say drinking one to three cups of coffee a day can reduce the risk of heart disease by 30 per cent. In addition, coffee has an alleviating effect on pollen allergy and asthma. Coffee: it's not for everyone. Even if it's as good as a thousand, it's best for some people not to touch it.
