Common sense of drinking coffee how much coffee suits your body best
There seems to be a constant debate about whether coffee brings more health benefits or more harm. How much coffee should I drink every day?
1 cup of coffee
The upside: Greek researchers studied 485 people over the age of 65 and found that one cup of coffee a day can keep arteries healthy and stabilize blood pressure. A survey of 600 volunteers at the University of Bristow in the UK also showed that one cup of coffee a day can boost brainpower.
The downside: it takes eight hours for caffeine to be fully excreted, so if you drink coffee after 3 or 4 p.m., it's easy to have sleep disorders.
2 cups of coffee
Benefits: a study by the University of Florida found that 200 milligrams of caffeine, equivalent to two cups of coffee, can prevent memory loss and Alzheimer's disease. Research in the International Journal of Sports Medicine also shows that drinking coffee 30 minutes before exercise can help improve performance.
The downside: if you are pregnant, you should consume less than two cups of coffee, otherwise it will increase the risk of miscarriage.
3 cups coffee
Benefits: a study published in the American Journal of Chemical Medicine found that three cups of coffee a day reduced women's risk of ovarian cancer by one percent. Men who drank three drinks a day had a 40% lower risk of gallstones.
The downside: a 2006 study in the United States showed that three cups of coffee a day increased heart rate and blood pressure slightly, which may increase the risk of heart attack.
4 cups coffee
The upside: a study by the University of Utah found that four cups of coffee contained about 400 milligrams of caffeine, which reduced the risk of oral and throat cancer by 39 percent. In addition, it can reduce the risk of colon cancer, breast cancer and type 2 diabetes.
The downside: four cups of coffee a day doubles the risk of rheumatoid arthritis.
More than 5 cups
The upside: a 10-year study of 90,000 people by researchers in Tokyo found that five cups of coffee a day reduced the risk of liver damage by three to four.
The downside: caffeine interferes with calcium absorption and increases the risk of osteoporosis. Drinking too much will accelerate the loss of minerals and vitamins in the body. While increasing high blood pressure, it also increases the risk of cardiovascular disease.
Even if there are many reasons why you love coffee, make it a good partner for a healthy life first. Therefore, experts warn that for most people, the total daily intake of caffeine had better not exceed 250 mg, which is equivalent to drinking 3 cups of coffee.
