Worldwide, experts estimate that people consume around 2.25 billion cups of coffee per day. I know a coffee group that does 10% of that themselves.
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. As always check the links and references for yourself.
Coffee contains a number of useful nutrients, including riboflavin (vitamin B-2), niacin (vitamin B-3), magnesium, potassium, and various phenolic compounds, or antioxidants. Some experts suggest that these and other ingredients in coffee can benefit the human body in various ways.
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
In the sections below, we cover these benefits in more detail.
1. Coffee and diabetes
Coffee may help protect against type 2 diabetes.
In 2014, 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.
A meta-analysis from 2017 concluded that people who drank four to six cups of either caffeinated or decaffeinated coffee each day appeared to have a lower risk of metabolic syndrome, including type 2 diabetes.
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.
One team concluded that men who drink over four cups of coffee per day might have a fivefold lower risk of Parkinson’s than those who do not.
In addition, the caffeine in coffee may help control movement in people with Parkinson’s, according to one 2012 study.
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.
There was not enough evidence to prove that drinking decaffeinated coffee would help prevent Parkinson’s disease, however.
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.
Also, a 2019 literature review concluded that “coffee intake probably reduce the risk of liver cancer.”
4. Coffee and heart health
People who drank moderate amounts of coffee each day had an 11% lower risk of heart failure than those who did not.
Some studies, however, found higher levels of blood lipids (fat) and cholesterol in people who consumed more coffee.
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.
Coffee beans also contain polyphenols, a type of antioxidant.
Antioxidants can help rid the body of free radicals, a type of waste product that the body naturally produces as a result of certain processes.
In 2018, some researchers suggested that the antioxidant content of coffee may offer protection from metabolic syndrome.
The author of one article from 2017 note that although scientists can prove that certain compounds are present in coffee beans, it remains unclear what happens to them once they enter the human body.
In conclusion we see zero reason to ever not drink coffee, so we hope this article can help you deal with any negative Nancies in your life.
