A review that combined the results of nine studies found that
drinking more coffee is associated with lower risk of cirrhosis.
In the review, drinking one cup of coffee per day was shown to
be linked with a 22% reduced risk for cirrhosis, a liver
disease. Two daily cups were associated with a 43% reduced risk,
three cups with 57% reduced risk, and four cups with 65% reduced
risk.
A review of more than 200 studies found that people who drank
three or four cups of coffee per day were 19% less likely to die
from cardiovascular disease.
One large review of studies found that every additional cup of
coffee a person drinks per day was correlated with a 7% reduced
risk for developing Type 2 diabetes.
A meta-analysis of studies about coffee intake and brain health
calculated that regular coffee drinkers were approximately 16%
less likely to suffer from Alzheimer's, dementia, or cognitive
decline.
A large study of more than 500,000 European people found that
during a 16-year period, men who drank three or more cups per
day were 12% less likely, and women who did the same were 7%
less likely to die from circulatory and digestive diseases and
had healthier livers.
