Coffee may be linked to lower risk of death

New research by the Division of Epidemiology and Genetics of the National Cancer Institute in the United States found that coffee consumption is linked to a lower risk of death The study, published in the New England Journal of Medicine

, involved more than 400,000 men.

and women living in six different states. At baseline, participants were between 50 and 71 years old and none had cancer, heart disease, or a history of stroke. Between 1995 and 1996, men and women completed a complete questionnaire to assess their diet and lifestyle . Nine out of 10 study participants drank coffee and some of the drinkers said they also consumed tea, a beverage that will be the focus of future analysis, according to the researchers. The authors followed the participants until December 31, 2008 or to date in which they died. After analyzing the results, they noticed that people who consumed three or more cups of coffee a day had about a 10% lower risk of death overall, and that the chances of death were also reduced for each ill cited individually, except for cancer. The researchers observed these results after considering the effects of other risk factors for death, such as smoking and drinking alcohol.

According to experts, the results of the study should be comforting for people who consume coffee, one of the most popular drinks the United States and the world. However, they do not advise anyone to start drinking coffee based on these results. That's because researchers can not be sure what caused the lowest death rate - whether it was the drink itself or some unmeasured feature of the people who chose to drink it. This type of study may show the association, but it can not say that coffee has driven people to live longer.

Coffee: benefits and harms at Yahoo! Video


Among the controversies about coffee are the fear of losing sleep and the association of the drink with the emergence of some diseases. "There is a lot of research on the subject and some have conflicting results," says endocrinologist Claudia Chang of the Brazilian Society of Endocrinology and Metabolism (SBEM). The only consensus, for the time being, establishes the maximum recommended amount per day: three or four cups of coarse coffee or half of it in the express version, which is more concentrated.

What are the risks of excessive consumption?

O Drinking more than three cups of caffeine a day can bring other risks, such as:

- High blood pressure (people with hypertension should avoid consuming more than 500mg / day of caffeine);

- Cardiac arrhythmia: Caffeine increases heart rate

- Worsening of gastric conditions, such as reflux and gastritis, because caffeine irritates the digestive system, especially when consumption is fasting

- Difficulty absorbing calcium because caffeine reduces intestinal absorption of this mineral, contributing to the onset of osteoporosis.

Children can drink coffee

Children can drink coffee, provided they do not exceed 45mg / day (about half a cup). The child's neurological system is more sensitive and too much caffeine can harm it. "But with this care in quantity, coffee can increase mental concentration and mood, helping children with attention deficit," says nutrologist Roberto Navarro, a specialist in My Life.

Are Pregnant Women Also Released?

Although the consumption of caffeine is not related to poor formation or delayed uterine growth, the ideal is that the pregnant woman does not consume very high amounts of caffeine, with a safe limit of 300mg / day, which is why excessive coffee consumption can lead to to the weight loss of the pregnant woman and the fetus.

Coffee really takes our sleep?

Yes. This happens because the consumption of caffeine blocks the action of a chemical component of the brain, which determines the need for sleep and awakens the urge to sleep. "The effects of caffeine persist for four to six hours after consumption, so one cup of coffee does not become a trigger for insomnia," says the endocrinologist.
