Pour yourself another Cup of coffee: researchers from Harvard found that those who consume more of this aromatic drink will be centenarians!
The researchers observed over 200 000 people for 28 years and found that nonsmokers who drink a day three to five cups of coffee, with caffeine or without, any causes of death — 15% lower than those who did not drink the coffee.
One of the factors the author of the study Frank Hu calls the powerful antioxidant called chlorogenic acid, which is contained in coffee, regardless of the percentage of caffeine. It can be the cause of lower mortality in coffee drinkers compared with those who did not drink. The number of deaths from heart attacks from coffee people is less than 19% and diabetes by 24%. According to Hu due to the fact that the cause of both diseases — inflammation, and coffee contains chlorogenic acid prevents their.
The researchers also found that among non-smokers who drink in the day 3-5 cups of coffee likely to die from neurodegenerative diseases such as Parkinson's disease, down 37% and the suicide rate is lower by 36% than in those who indulge in some tea. This relationship, says Hu, most likely due to the caffeine. "Caffeine stimulates the production of dopamine and the major cause of Parkinson's disease is to reduce the level of this substance," he says.
Caffeine can also increase levels of other neurotransmitters in the brain, which has a General antidepressant effect. Scientists do not give one single recommendation on the number of cups of coffee a day. Three to five is the Golden mean, since the decrease or increase of the dose of the subjects have led to a weakening of the above reactions.
