7.Heart Disease
Doctors once thought people with this should cut down on tea and coffee, because of the caffeine, but now it seems they may protect you from it. In one study, people who drank 3 to 5 cups of coffee a day were less likely to have a buildup of calcium in the vessels that bring blood to your heart muscle. That could mean a lower chance of heart disease.
8.Liver Disease
This is another organ that probably benefits from your morning cup of joe. Drinking 3 or more cups of coffee a day may lower your odds of having chronic liver disease, cirrhosis, and liver cancer — and it may be an alternative medicine for people who have those issues. Coffee has more than 100 different chemical compounds in it, and scientists are trying to figure out what they do and how they might work together to help your liver.
