Researchers in the U.S. have studied the link between coffee consumption and the risk of Parkinson’s disease. They concluded that higher coffee and caffeine intake leads to a significantly lower occurrence of Parkinson’s disease.
Moreover, caffeine in coffee may support easier movement in people suffering from Parkinson’s. This is the result of a study conducted at the Research Institute of the McGill University Health Centre.
Italian researchers concluded that coffee consumption decreases the risk of liver cancer by about 40%. Even some of the results suggest that three cups per day reduce the risk by more than 50%.
Regular consumption of coffee is connected to a reduced risk of primary sclerosing cholangitis. This is a rare autoimmune disease of the bile ducts in the liver.
In addition, coffee can lower the incidence of cirrhosis of the liver for alcohol drinkers by about 22%. This is according to a U.S. study at the Kaiser Permanente Medical Care Program.
The authors of the study concluded that drinking two or more cups per day is associated with a decreased death risk of liver cirrhosis – about 66%.
This benefit is not linked to caffeine content. A study published in the journal Hepatology indicates that drinking decaffeinated coffee also lowers liver enzyme levels.
Researchers at the Harvard School of Public Health concluded that moderate quantities of coffee daily protect against heart failure. As ‘moderate’ they have meant 2 European cups. This is equivalent to two 8-ounce American servings per day.
The authors have underlined that their results show a possible benefit, but it really depends on how much you drink. It is the same as with so many other things you consume.
Moreover, caffeine is also associated with symptoms of depression due to a theory that it causes abrupt changes in mood.
Women who plan to have a baby should be very cautious. Researchers from the University of Nevada School of Medicine reported that regular coffee intake may decrease the chances of a woman to become pregnant.
Other possible risks include:
- the negative effect on cardiovascular health in young adults with mild hypertension
- the disruption of the body clock
- the presence of mycotoxins in commercial coffee samples – This fact leads to concerns about potential risks for public health.
