What Three Cups of Coffee a Day Can Do for Your Liver

Did you know that several cups of coffee a day might be good for your health? In fact, there are already several studies that show that coffee consumption can be very beneficial to health, as long as it’s consumed in moderate amounts.

Until just a few years ago, many people avoided drinking this substance because they believed that it was harmful to the body due to its caffeine content. However, year after year new research has been done, and it’s been proving that coffee consumption in moderation is actually beneficial for our health.

Even so, in the case of any medical problem, it’s essential to talk with your doctor to ensure that it’s the best choice for you.

The research on coffee

Several studies have shown that coffee has positive effects in the treatment and prevention of problems such as diabetes, Alzheimer’s, and even Parkinson’s disease. Now, new studies give us another important reason to drink more coffee and enjoy its benefits.

In a study conducted by the National Cancer Institute in Bethesda (Maryland, USA) and published in the journal Hepatology, it was revealed that coffee consumption has positive effects on the liver.

To carry out this research, scientists used data from the US National Health and Nutrition Examination Survey (NHANES, 1999-2010). They selected a total of 27,793 participants over the age of 20.

The volunteers filled out a survey about their coffee drinking habits and the researchers measured their blood levels of various markers of liver function.

The purpose of this survey was to measure the liver health of the participants. Overall, it was found that those who consumed three or more cups of coffee a day had lower levels of liver enzymes compared to those who didn’t consume coffee.

In conclusion, the researchers determined that compounds in coffee other than caffeine promote liver health when consumed in moderation.

Several cups of coffee a day reduces the risk of fibrosis

In other research, also published in the journal Hepatology, it was revealed that coffee consumption significantly reduces the increased build-up of connective tissue (fibrosis) in the liver in patients with non-alcoholic fatty liver disease.

The research determined that caffeine can reduce fibrosis in people with fatty liver disease. It can also do this in people with chronic liver disease.

To conduct this research, scientists interviewed 306 people about their caffeine intake and divided them into four groups to be graded: patients with no signs of fibrosis on ultrasound (the control), steatosis, stage 0-1 non-alcoholic steatohepatitis (NASH), and stage 2-4.

Patients with this condition who consumed this substance showed a significant difference compared to patients with NASH stage 0-1.

Interestingly, coffee consumption was higher in patients with NASH stage 0-1, with 58% of caffeine intake from normal coffee, compared to NASH stage 2-4 patients, with only 36% of caffeine intake from normal coffee.

However, according to experts, more evidence and research are needed to examine the amount of consumption of this substance in clinical outcomes.

The health benefits of coffee

Overall, the benefits of this substance are becoming more and more evident. This is despite the fact that it was long believed that it could be harmful to health. However, it’s always best to consult a doctor if you have any health problems.

That said, here are some of the newly discovered benefits of coffee:

  • Recent research has determined that this substance may prevent and protect against diabetes.
  • Because of its high content of antioxidants, it’s linked to the protection against cell damage by free radicals.
  • Regularly drinking coffee reduces the risk of cirrhosis.

  • Also, it reduces the risk of suffering heart disease thanks to its high content of flavonoids.
  • Its consumption is linked to the reduction of the risk of gallstones and gallbladder diseases.
  • Finally, coffee feeds the bacterial flora in our intestines, which benefits our digestive system.

However, hypertensive patients with uncontrolled blood pressure should avoid large doses of caffeine. In people with well-controlled blood pressure, coffee consumption is probably safe. However, this hypothesis needs to be confirmed by further research.
