When people think of coffee, they usually think of its ability to boost energy. However, according to some research, it may also present some other important health benefits, such as lower risk of liver cancer, type 2 diabetes, and heart failure.
Worldwide, experts estimate that people eat approximately 2.25 billion cups of coffee daily.
Researchers have considered the benefits of drinking enough in conditions such as diabetes, cardiovascular disease, inflammatory bowel disease, and liver disease. There is evidence to support some, but not all, of these claims.
Coffe contains many 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.
This article considers the health benefits of drinking coffee, the evidence supporting these benefits, and the dangers of drinking coffee.
5 benefits of drinking coffee
Health benefits of drinking coffe include:
- Protect against type 2 diabetes, Parkinson’s disease, liver disease, and liver cancer.
- Promoting a healthy heart
In the following sections, we cover these benefits in more detail.
1. Coffee and diabetes
Cofee can help protect against diabetes type 2.
In 2014, researchers who collected data from more than 48,000 people found that people who increased their cofee consumption by at least one cup per day over 4 years 11% had a lower risk of type 2 diabetes who did not increase their intake.
A meta-analysis of 2017 concluded that people who drink four to six cups of either caffeine or defined cofee daily 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 found in coffee and many other beverages, can help protect against Parkinson’s disease.
One team concluded that men who drink more than four cups of alcohol a day may have a five-fold lower risk of Parkinson’s.
In addition, according to a 2012 study, caffeine in cofee can help control movement among people with Parkinson’s.
The 2017 meta-analysis investigated the association between coffe use and the low risk of Parkinson’s disease, even among smokers. The team also found that people who drink coffee are less likely to have mental stress and academic conditions such as Alzheimer’s.
However, there was not enough evidence to prove that drinking defective coffee would help prevent Parkinson’s disease.
3. Coffee and liver cancer
Italian researchers found that cofee consumption reduces the risk of liver cancer by about 40-40%. Some results suggest that people who drink three cups daily may have a 50% lower risk.
Also, a 2019 literature review concludes that “drinking coffee probably reduces the risk of liver cancer.”
4. Coffee and other liver diseases
A meta-analysis of 2017 concluded that drinking coffe of any kind reduces the risk of liver cancer, non-alcoholic fatty liver disease, and cirrhosis.
People who drink coffee may also have a lower risk of stone disease.
In 2014, researchers looked at coffee consumption among people with atrial sclerosing cholangitis (PSC) and primary biliary cirrhosis (PBC). These are autoimmune conditions that affect the gastrointestinal tract.
They found that people with PSC were less likely to drink cofee than those without a condition. There was no evidence that people with or without PBC differed significantly.
Also, a 2014 study suggested a link between coffee consumption and low risk of dying of hepatitis-related hepatitis. Researchers suggest that drinking two or two cups of coffee daily can reduce the risk by 66 percent.
5. Coffee and heart health
A 2012 study concluded that drinking moderately, or consuming two 8 ounces a day, can prevent heart disease.
The risk of heart disease is 11% lower than those who drink moderate amounts daily.
A 2017 meta-analysis found that caffeine consumption could have the least benefit for cardiovascular health, including lower blood pressure.
However, in some studies, high levels of blood lipids and cholesterol have been found in people who drink more coffee.
Regular black coffee (without milk or cream) is low in calories. In fact, a typical cup of black coffee contains only 2 calories. However, adding cream or sugar will increase the cost of heat.
Coffe beans also contain a type of antioxidant polyphenol.
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.
Free radicals are toxic and can cause swelling. Scientists have found links between inflammation and various aspects of metabolic syndrome, including type 2 diabetes and obesity.
In 2018, some researchers suggested that coffee’s antioxidant content may protect against metabolic syndrome.
The author of a 2017 article noted that although scientists can prove that there are some compounds in coffee beans, it is unclear what happens to them once they enter the human body.
Excessive drinking may also have some adverse effects. In the sections below, we cover some of these risks.
Some studies have found that women who drink too much coffee have a higher risk of bone breakdown.
Men who drink more alcohol, on the other hand, are slightly less at risk.
Researchers said that coffee consumption may not be safe during pregnancy. In fact, there is some evidence to suggest a link between adequate pregnancy and pregnancy loss, low birth weight and premature birth.
Women who drink coffee may have an increased risk of endometriosis, but there is not enough evidence to confirm such a link.
Gastroesophageal reflux disease
People who drink in plenty have a slightly higher risk of this condition.
Consumption of sufficient caffeine can increase the risk of anxiety, especially in people with panic disorder or social anxiety disorder. Generally, it can trigger frenzy and psychosis in people who are sensitive.
A 2016 study concluded that overuse of caffeine during adolescence can lead to permanent brain changes.
The scientists behind the study expressed concern that this could increase the risk of anxiety-related conditions in youth.
Presence of toxic ingredients
In 2015, researchers found relatively high levels of mycotoxins in commercial coffee. Mycotoxins are toxic substances that can contaminate coffee as a natural product.
Some people worry that another chemical acrylamide in coffee can be dangerous.
A meta-analysis of 2017 concluded that consuming three to four cups of coffee daily is “generally safe” for most people, and doing so actually reduces the risk of certain health conditions. can go.
However, the study’s authors warn that smoking may cancel out the benefits of drinking coffee.
Caffeine is an important feature of coffee, but coffee contains many compounds, and there are different ways to drink it. This makes it difficult to determine exactly how much a person affects and what ingredients have their benefits and risks.
A person who wants to get the health benefits of coffee should avoid the daily recommended dosage and keep an eye on their ingredients, such as sugar, cream or flavor, as they may not be healthy.
Pregnant women and those at risk for bone fractures may want to avoid cofee.
