Scientists Discover a New Benefit of Drinking Coffee
Coffee is one of the most controversial
drinks in existence. In the past, many believed that it causes
cardiovascular disease, but more recent research suggests that the
antioxidant-rich drink actually has numerous health benefits, provided
that you don’t drink more than a few cups of coffee every day. Among the
notable health benefits of coffee are improved heart and brain health,
as well as a reduced risk of certain types of cancer. But there’s one
more health benefit we can now confidently add to that list - liver
health.
This is the biggest study yet to find that
coffee benefits liver health
Liver disease is a widespread health issue all around the world, and
it’s on the rise too. More recent estimates suggest that one in ten
Americans suffers from some kind of liver disease. Fatty liver disease
and liver cirrhosis are among the most common kinds of liver disease.
According to a recent study from the United Kingdom, drinking coffee
lowers one’s risk of liver disease.
The study followed 495,585 people for 10
years. 78 percent of the participants consumed ground coffee, instant
coffee, or decaf, whereas the remaining 22 percent didn’t drink coffee.
Over the ten-year period, 3,600 cases of fatty liver disease and 184
cases of liver cancer were recorded.
The study found that liver disease was more common among the
participants who didn’t drink coffee. Among the coffee drinkers, the
risk of liver disease fell by 21 percent and the risk of death from
chronic liver disease was reduced by 49 percent compared to those who
didn’t drink coffee. Researchers believe that the anti-inflammatory or
anti-fibrotic properties of coffee may be why it’s beneficial for liver
health.
“There are previous studies suggesting lower risk of cirrhosis (severe
liver scarring), improvements in fatty liver disease, lower rates of
hospitalization and mortality in cirrhosis, associated with coffee use,”
stated Dr. Albert Do, a Yale Medicine hepatologist and fatty liver
disease expert to Healthline. So this study is a big contribution to an
already existing belief among experts that coffee is beneficial for the
liver. The researchers conclude that coffee is an accessible and
affordable drink capable of reducing one’s risk of liver disease.
Do instant, decaf, and ground coffee have the same effect?
Although both decaf and instant coffee were
associated with some health benefits, the beneficial effect was the
strongest in the group who drank ground coffee. The researchers believe
that this is due to the fact that ground coffee has the most cafestol
and kahweol — two compounds naturally present in coffee believed to
protect the liver. This doesn’t mean that you should switch to ground
coffee, as you’ll still experience some benefits from decaffeinated
coffee, especially if you opt for decaf for health reasons.
How much coffee should drink to feel the effects?
The study found that the health benefits plateaued at 4-5 cups of coffee
daily. This doesn’t mean that you should drink that much, but rather
that there’s no point in drinking more than 4 cups of coffee a day. Even
if you drink 1-2 cups of coffee a day, you should experience the same
benefits.
Experts usually don’t recommend drinking more than 400mg of coffee a day
(which is about 3-4 cups of coffee) because all the benefits of coffee
are only relevant when consuming caffeine in moderation. The moment you
increase your caffeine intake to more than 400 mg a day, the negative
effects, such as a racing heart and cardiovascular issues start to kick
in.
Those who suffer from heart disease, high blood pressure, and heartburn
should be especially careful when drinking any amount of coffee. With
that said, those who enjoy their morning coffee daily will probably be
glad to find out that their coffee drinking habit is healthier than they
think.
