On its way through the gastrointestinal tract, coffee has the main effects on the body, scientists say, on gastric, bile, and pancreatic secretion.
A review of nearly two hundred scientific publications has shown that moderate coffee consumption – three to five cups a day – does not harm the digestive system, but rather reduces the risk of gallstones, pancreatitis, and certain liver diseases.
On its way through the gastrointestinal tract, coffee has three main effects – on gastric, biliary, and pancreatic secretions, which are necessary for food digestion, on the gut microbiota, and on the contraction of the colon walls (a process necessary for food to pass through the digestive tract).
In addition, an analysis of 194 studies has shown that coffee, when consumed in moderation, stimulates digestion and helps pass through the colon – including increasing the number of “good bacteria” in the intestines, reducing the risk of gallstones, and having a protective effect on the liver.
The results of the study also showed that coffee stimulates the production of the digestive hormone gastrin and hydrochloric acid in gastric juice. Both of these substances help break down food in the stomach.
