How Much Coffee Shall We Drink?

There are dozens of reasons for people to fall in love with coffee. It is a good friend of many people. The heated discussion about whether it is good for health or not has never stopped. How much coffee shall we drink everyday? It is up to you. But before you make a decision, you must know its advantages and disadvantages. One cup of coffee is good for your brain and heart. Greek researchers surveyed 485 senior citizens who were older than 65 years old. They found that one cup of coffee would keep arteries healthy and stabilize blood pressure. Similar studies have made in Britain. Experts at Bristol University studied 600 volunteers and made a conclusion that a cup of coffee can strengthen the brain. But it costs eight hours to discharge caffeine entirely from the body. Therefore, do not drink coffee after three or four o’clock in the afternoon. Or, it would be difficult for you to go to sleep. Experts suggest that most people are not suggested to ingest more than 250 milligrams of caffeine, which equals to two or three cups. Two cups of coffee make you have a good memory. It is estimated that 200 milligrams of caffeine can help people enhance memory and prevent dementia. So such an amount does goods to the elderly and people who do brain work a lot. But according to the Daily Mail published on May 23rd, American experts point out that excessive coffee would make women difficult to get pregnant. Caffeine would interfere with the normal activity of ovum. In other words, it cannot reach uterine successfully from ovary. Pregnant women should not drink so much, too. Otherwise, they are easy to lose babies. American medical magazines have reported that three cups of coffee a day is helpful for women to prevent ovary cancer and for men to reduce the risk of gall-stone by 40%. But it is too much for people have a poor heart. It will increase their heart beat and raise their blood pressure as well. The advantages of coffee focus on its cancer resistance. Professors at Utah University carried out an experiment and concluded that 400 milligrams of caffeine is able to help decrease the chance of throat cancer by 39%. At the same time, it is useful in resisting colon cancer, breast cancer and diabetes. However, if people drink as many as four cups, they would be much easier to get rheumatoid arthritis. Five cups or more are too many for ordinary people. Excessive coffee affects the absorption of calcium. Vitamins and minerals would be lost at a high speed. In consequence, cardiovascular diseases and bone problems start to trouble people. But to our surprise, so much caffeine would protect the liver from being damaged.
