The effects of coffee consumption on health have long been a subject of conflict and uncertainty.Since the 1980s,some have spoken out against coffee as harmful to health,while others have welcomed coffee for its supposed benefits to health.

According to a scientific report,mild coffee consumption,three to five cups per day,can he taken as a healthy dietary pattern,along with other healthful behaviors.The report also says that coffee consumption helps reduce the risk of heart disease and it protects against Parkinson's disease.

According to Dr.Donald Hensrud of Mayo Clinic,high consumption of coffee has health risks.Dr.Hensrud mentions the dangers of high coffee consumption for people with a certain illness that slows the breakdown of caffeine in the body.Some studies said that drinking two or more cups of coffee daily can actually increase the risk of heart disease in these people.

According to conclusions from a recent study led by Dr.Gregory Marcus,a doctor from the University of California San Francisco,daily moderate consumption of caffeine,less than 4 cups,is not associated with these issues.

Until the scientific community reaches a general agreement on the effects of coffee consumption on human health,it will be up to the individual to decide whether the benefits of drinking coffee are greater than the risks.
