One cup of coffee a day is supposedly enough for developing narcotic dependence
Coffee, the most popular drink on planet Earth, has been studied and analyzed all over the world. It seems that every country, which can boast of having a scientific institute, regularly conducts special research works about coffee, its qualities and influence on humans. Looks like researchers in different countries are obsessed by the desire to look deep into this invigorating beverage.
Coffee stirred up a debate shortly after it was discovered. The debate still lingers. An expert opinion on coffee by Dr. Colombo at the University of Marseilles in 1679 said that “the beverage has the burnt particles in large numbers, which are so powerful they can destroy all the lymph and dry out the kidneys. The particles can also disrupt water supply of the brain.” According to the French scientist, coffee drinkers will invariably suffer from exhaustion, paralysis, and impotence.
More than 300 hundred years have passed since the above conclusions were made. Nevertheless, the past, the present-day researchers keep finding new harmful properties of coffee.
According to Roland Griffiths at John Hopkins Institute, one cup of coffee is enough for developing narcotic dependence. He cites the caffeine “cravings” e.g. headache and muscular ache, fatigue, lack of concentration and nausea caused by caffeine “withdrawal” in half of those who drink coffee regularly. In view of the above, the researcher suggests that coffee addiction be put on the list of psychiatric and drug-abuse diseases.
Caffeine, a key ingredient of the beverage, is a stimulant that can cause a temporary blood pressure elevation and a faster pulse rate. That is why persons with hypertension and heart problems were told to refrain from drinking coffee.
Greek researchers at Henry Dunant Hospital in Athens believe that one cup of coffee a day can increase the risk of developing cardiovascular diseases. According to them, a cup of coffee will lead to a sharp increase of caffeine content in blood; harden the walls of the vessels, and raise blood pressure.
Cardiologists at the University Hospital of Zurich stand up for the favorite beverage of the millions. They claim that coffee can only raise blood pressure in those who drink it on rare occasions. Regular coffee drinkers are not risk if they have another cup or two.
Walter Vilette from Boston conducted a lengthy experiment to find possible links between ischemia and the coffee drinking. For 10 years The researcher was monitoring the state of health of 85,747 nurses, from 1980 through 1990. The results of the experiment show that there is no link whatsoever between ischemia and coffee, not in female patients at the least. Even six coffees a day would not result in a greater risk of the disease.
Below are some pros of coffee:
- coffee is good for the gall bladder ( reduces the risk of gallstones formation thanks to bile-excreting effects of the caffeine;
- coffee makes life easier for asthmatics, it brings out bronchodilation or a widening of the air passages;
- coffee protects the liver against the harmful effects of alcohol and reduces the risk of liver cancer;
- coffee enhances the efficiency of antibiotics;
- coffee is an excellent antioxidant capable of neutralizing oxygen free radicals that damage the cells. Therefore coffee can reduce the incidence of a number of serious diseases.
