Coffee and health

When people think of coffee, they usually think of its ability to provide an energy boost. However, according to some research, it can also offer some other important health benefits.

Worldwide, experts estimate that people consume around 2.25 billion cups of coffee per day.
Researchers have looked at the benefits of drinking coffee for conditions such as diabetes, cardiovascular disease, inflammatory bowel disease, and liver disease. There is evidence to support some, but not all, of these claims.

The potential health benefits associated with drinking coffee include: protection against type 2 diabetes, Parkinson’s disease, liver disease, and liver cancer, the promotion of a healthy heart.

1. Coffee and diabetes

Coffee may help protect against type 2 diabetes. Researchers who gathered data on over 48,000 people found that those who increased their coffee consumption by at least one cup per day over 4 years had an 11% lower risk of type 2 diabetes than those who did not increase their intake.

2. Coffee and Parkinson’s disease

Various studies have shown that caffeine, which is present in coffee and many other beverages, may help protect against Parkinson’s disease.
The findings of a 2017 meta-analysis suggested a link between coffee consumption and a lower risk of Parkinson’s disease, even among people who smoke. This team also found that people who drink coffee may be less likely to experience depression and cognitive conditions such as Alzheimer’s.

3. Coffee and liver cancer

Italian researchers found that coffee consumption lowers the risk of liver cancer by around 40%. Some of the results suggest that people who drink three cups per day might have a 50% lower risk.

4. Coffee and other liver diseases

A meta-analysis from 2017 concluded that consuming any type of coffee appeared to reduce the risk of liver cancer, nonalcoholic fatty liver disease, and cirrhosis.

People who consume coffee may also have a lower risk of gallstone disease.

5. Coffee and heart health

One 2012 study concluded that drinking coffee in moderation, or consuming around two 8-ounce servings per day, may protect against heart failure.

One 2017 meta-analysis found that caffeine consumption may have at least a small benefit for cardiovascular health, including blood pressure.

Some studies, however, found higher levels of blood lipids (fat) and cholesterol in people who consumed more coffee.

6. Nutritional value

Regular black coffee (without milk or cream) is low in calories. In fact, a typical cup of black coffee only contains around 2 calories. However, adding cream or sugar will increase the calorific value.

A person who wishes to derive health benefits from coffee should avoid exceeding the daily recommended intake and try to monitor the ingredients they add, such as sugar, cream, or flavorings, as these may not be healthful.
