Is coffee really good for you?
The health effects of coffee have been studied extensively. Sometimes praised for its benefits for the cardiovascular system, sometimes criticized for its deleterious effects on the stomach, the little black boy does not make everyone agree. We come back to the health consequences of drinking coffee.
According to the results of a recent study by the Havard T.H. Chan School of Health, American school of medicine, regular coffee consumers are less likely to die prematurely than non-drinkers. But the studies in this area are numerous (150 studies carried out in 2012 alone) and their results contradictory.
What is coffee?
Coffee is cultivated in more than 70 countries, especially in Brazil and Colombia. Three quarters of production is Arabica coffee; its caffeine content varies from 0.8 to 1.3%. Robusta coffee has a higher caffeine content, between 2 and 2.5%. It is mainly cultivated in West Africa.
Several bioactive compounds stand out from the dozen present in coffee: the best known, caffeine, regulates brain excitability. The polyphenols contained in the drink also play an important role thanks to their antioxidant properties.
How is it good for your health?
The Harvard Chan School of Healt comparative study was performed on guinea pigs drinking between two and five cups of coffee per day. The results show that there is a lower risk for consumers of dying from cardiovascular disease, parkinson’s, diabetes or even suicide. “This study provides evidence that moderate coffee consumption can have benefits in reducing the risk of dying prematurely from various diseases,” the study concludes.
The benefits of coffee are therefore very real for regular consumers. If you take two to three cups of coffee a day, or 200 to 300 mg of coffee, then rejoice, coffee tastes good! count for an espresso about 70 mg to 100 mg of coffee.
In the case of moderate consumption, coffee can reduce:
- The risks of digestive cancers, in particular, colon cancer
- Cirrhosis of the liver and memory loss
- Parkinson’s diseases
- The risks of depression. The presence of dopamine acts as a mild anti-depressant. Here, we recommend four cups of coffee a day to see the risk of feeling depressed reduced to 20%.
- Erectile dysfunction: one or two espressos daily reduce the risk of dysfunction by 42%.
Note otherwise, the effects of caffeine last six to eight hours and increase attention.
Is there a limit that should not be exceeded?
Unfiltered, coffee increases cholesterol due to the lipids present in its beans. This diuretic promotes urinary production and can, beyond three cups a day, cause disorders such as incontinence.
While moderate caffeine consumption is good for your health, various studies on the subject suggest that excessive consumption could increase the risk of cardiovascular disease and cause heartburn.
Therefore be wary of starting at five cups a day, for women in particular, because the success of in vitro fertilization can be reduced by half. As for postmenopausal people, coffee in excessive dose increases the risk of osteoporosis. It is also customary to limit pregnant women to one cup of coffee per day.
Coffee can also be stressful or calming, depending on the person. Reactions vary. While coffee increases anxiety for some, others use it as a tranquilizer. Above all, it is about listening to yourself.
