Coffee consumption is associated with a lower risk of developing chronic liver diseases (such as hepatitis) and fatty liver, writes focus.it.
The preventive effect is found with all types of coffee, including instant coffee and decaffeinated coffee.
Scientists at the University of Southampton (UK) analyzed data from 494,585 participants in Great Britain, a database used to study genetic or environmental factors associated with certain health conditions.
Among these people were 384,818 coffee drinkers and 109,767 people who did not drink coffee. All participants were between 40 and 69 years old.
The researchers followed them for an average of nearly 11 years, during which they monitored their liver health. In this period, there were 3,600 cases of chronic liver disease with 301 deaths, and 1,839 cases of fatty liver, a condition that can lead to excessive inflammation of the organ and even serious complications.
Does drinking coffee prolong life?
After taking into account other factors that can affect liver health, such as smoking or alcohol habits and body mass index, it was found that those who drank any amount and type of coffee had a 20% lower risk of developing chronic liver disease compared to people who do not consume it.
Those who drank coffee according to the study had a 49% lower risk of dying from the same causes.
The protective effect increases with the amount of coffee consumed, but up to 3-4 cups per day: after this threshold no further benefits are observed. It is not yet understood on which substance this apparent beneficial effect may depend.
At the moment it is not possible to say with certainty that coffee in moderate doses protects the liver, as a medicine, even if indications of benefits, in the liver, kidneys and have been found in other studies before.
While they wait to understand if and how this positive connection can be harnessed, experts recommend taking care of your liver in traditional ways, avoiding excessive alcohol consumption, exercising, eating well and maintaining a healthy body weight.
