How many cups of coffee can I drink every day? The advantages and disadvantages of drinking coffee
The debate over whether coffee does more good or harm seems to be ongoing. How much coffee should I drink every day?
1 cup coffee
The good: Greek researchers who studied 485 people over the age of 65 found that a cup of coffee a day kept arteries healthy and blood pressure stable. A survey of 600 volunteers at the University of Bristol in the UK also showed that a cup of coffee a day can boost brain power.
The bad: Caffeine takes eight hours to be completely excreted, so if you drink coffee after 3 or 4 p.m., you are prone to sleep disorders.
2 cups of coffee
Benefits: A University of Florida study 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 showed that drinking coffee 30 minutes before exercise improves performance.
Cons: If pregnant, coffee intake should be less than two cups, otherwise it will increase the risk of miscarriage.
3 cups of coffee
Benefits: Three cups of coffee a day can cut a woman's risk of ovarian cancer by a fifth, according to a study published in the American Journal of Chemical Medicine. Men who drank three cups a day had a 40 percent lower risk of gallstones.
The bad: A 2006 U.S. study 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 of coffee
Benefits: A University of Utah study found that four cups of coffee, containing about 400 milligrams of caffeine, reduced the risk of oral and throat cancer by 39 percent. It also reduces the risk of colon cancer, breast cancer and type 2 diabetes.
The bad: 4 cups of coffee a day doubles the risk of rheumatoid arthritis.
More than 5 cups
Benefit: A 10-year study of 90,000 people by Tokyo researchers found that five cups of coffee a day reduced the risk of liver damage by three-quarters.
Caffeine interferes with calcium absorption and increases the risk of osteoporosis. Drinking too much accelerates the loss of minerals and vitamins from the body. Along with raising blood pressure, it also increases the risk of cardiovascular disease.
Even though there are many reasons why you love coffee, make it a good partner for a healthy life first. Therefore, experts caution that for most people, it is best not to consume more than 250 mg of caffeine per day, which is equivalent to drinking 2-3 cups of coffee.
