If you love getting up for a cup of coffee in the morning, you (and your gut) are in serious luck. According to a recent review it posted NutrientsAnd The habit of drinking coffee can help your digestive system — including your intestines and liver.
The review, which was supported by the Institute for Scientific Information on Coffee, evaluated 194 different publications and concluded that moderate coffee drinking (about three to five cups per day) causes no adverse effects on the digestive system. In fact, drinking coffee has been linked to a healthy gut flora (maintaining healthy gut bacteria in the body), positively affecting the digestive system and colon, and even reducing the risk of liver disease.
How does this work? All of this is actually related to the caffeine that is naturally present in coffee. The caffeine in coffee can help stimulate a digestive hormone in the body called gastrin, as well as hydrochloric acid in the stomach. Stimulating them helps break down food in the stomach, while also stimulating cholecystokinin, a hormone that stimulates the secretion of bile and is important during digestion.
This, of course, seems to contradict some of the previous claims about coffee, which some believe may cause digestive problems. However, this review debunks the claim and delves into how coffee actually helps with digestion.
How does this specifically help the liver?
While this review outlines multiple ways coffee can help with digestion, one of the main points the review concludes is how Coffee strongly supports liver function and reduces the risk of developing liver diseases such as hepatocellular carcinoma, a common type of liver cancer.
This claim is also supported by my published 2021 study Public Health BMCWhich concluded that drinking a moderate amount of coffee per day (three to four cups) can reduce the risk of all chronic liver diseases including fatty liver disease and liver cancer.
Fortunately, drinking a few cups of coffee a day (even the caffeinated ones) is still perfectly good for one’s health. An 8-ounce cup of coffee contains 100 milligrams of coffee, and the FDA says you should limit your caffeine intake to 400 milligrams per day. That’s the equivalent of four cups of coffee a day!
So drink – it’s really good for you! Especially if you drink it black.
