Health benefits of coffee
Studies about the benefits of coffee
We all have heard about the risks of having too much coffee, it can have some detrimental effects in our health if we suffer for example from blood pressure, hypertension...etc. But as everything in life anything in excess is bad, and coffee is not exception for that, however recent studies on the health benefits of coffee may help us change our minds about the risks of having coffee. In this article we covered some of the claimed health benefits of coffee and some of the scientific evidence supporting those claimed health benefits of coffee.

Common name: Coffee
Doctors frequently limit the intake of caffeinated drinks as tea, coffee and soft stimulant drinks to patients suffering from hypertension, blood pressure and sleep disorders, but scientists may have found some health benefits of coffee.
ASSOCIATED RISKS TO THE INTAKE OF COFFEE
A recent analysis of existing studies on coffee and the risks associated to the intake of coffee performed by the Department of Gastroenterology of the Fudan University in Shanghai, shows that out of 59 studies found in different medical databases, the overall outcome was that an increase in consumption of one cup of coffee per day was associated with a 3% reduced risk of cancers.
Beverages as green tea have been already proven to be beneficial for the protection of women against breast cancer.
Among the types of cancer on which such reduction was noticed they were mentioned bladder, breast, bucal and pharyngeal, colorectal, endometrial, esophageal, hepatocellular, leukemic, pancreatic, and prostate cancers.
COFFEE AND BREAST CANCER OCCURRENCE
It was believed that the intake of coffee and tea on a regular basis may have had an influence in the occurrence of breast cancer, but some studies, among them one from the University Medical Center of Utrecht, The Netherlands, shows that out of 27,323 participants followed on this study on the incidence that coffee and tea intake may have in the occurrence of breast cancer, there were no results that can give evidence of a link between coffee and tea consumption and a related risk of breast cancer , something that other studies on the subject had already supported .
There are even some cohort studies that suggest that there may even be more incidences of breast cancer in women that do not consume coffee, tea or caffeine than in those ones that do have a regular consumption of coffee, tea and caffeine beverages .
GREEN TEA AND BREAST CANCER
Beverages as green tea have been already proven to be beneficial for the protection of women against breast cancer , however this may be due to other factors not related to the intake of caffeine. As we know, tea and coffee, among others (nuts, seeds, wine...etc.) contain benzopyrones, a group of active constituents that include also coumarins and flavonoids.
The western diet contains 1g/day of mixed benzopyrones, and knowing that coumarins are a natural substance known to have a very important anti-tumour activity, it may well be that some of those active constituents are the reason why coffee and tea have those beneficial protective properties.
However not everything is positive in coffee, another study , published by the British Journal of Pharmacology, shows how coffee can have a negative effect and reduce fertility in women.
