Beneficial effects of coffee
The effects of coffee on the human body are to be mainly attributed to the caffeine, but also in good measure to other components. The effects of caffeine depend on the type of coffee used (every quality has a different quantity of caffeine), and on the body of the person.
Coffee drunk regularly halves the risk of liver cancer and reduces that of breast cancer and cancer of the colon due to a substance called methyl-pyridinium, that has strong anti-tumour properties.
It has a stimulating effect on the central nervous system, acting on the synapses, reducing the sensation of tiredness and increasing efficiency. It also stimulates digestion and bowel movement. Only a few know of the good level of potassium and niacin.
Scientific literature has recently given positive evidence not only regarding the increase in mental performance in elderly persons, but also in the prevention of Parkinson’s disease and Alzheimer’s disease.
Coffee contains fewer oxidants than tea. On the other hand, several researchers have found that caffeine has good analgesic properties, particularly useful in cases of headaches. Drinking just two cups of coffee a day does not cause any undesired effects. Rather, it makes one more reactive and stimulates the short-term memory.
