Drinking coffee may help reduce the risk of certain digestive disorders, including gallstone disease and pancreatitis, a new study has suggested.
"Data indicates benefits against common digestive complaints such as constipation, as well as a potential reduction in the risk of more serious conditions like chronic liver diseases," said study author Carlo La Vecchia from the University of Milan in Italy. Gallstone disease is a common digestive disorder, caused by the accumulation of gallstones in the gallbladder or bile duct, which affects approximately 10-15 per cent of the adult population.
The study from the Institute for Scientific Information on Coffee (ISIC) also highlighted other beneficial effects that coffee consumption may have on the process of digestion, including supporting gut microflora and promoting gut motility.
While the mechanism by which coffee may protect against gallstone disease is not yet known, it has been observed that the risk for the condition declines with increasing daily consumption of coffee, the researchers said. Caffeine is thought to play a role in these associations, as the same effect is not observed with decaffeinated coffee.
A common question among consumers and focus area for research is whether coffee is associated with heartburn or gastro-oesophageal reflux disease (GORD). While a small number of studies have suggested an association between coffee drinking and GORD, the majority of studies reviewed suggest that coffee is not a major trigger of these conditions.
The report also reviewed a growing area of health and nutrition research, namely: the effect of coffee on the gut microflora (microorganism populations). Recent studies suggest that populations of the beneficial gut bacteria Bifidobacterium spp, increase after drinking coffee.
The findings showed the dietary fibre and polyphenols found in coffee, support the healthy growth of microflora populations.
Additional research findings highlighted that coffee consumption is thought to stimulate digestion by encouraging the release of gastric acid, bile and pancreatic secretions. Coffee is one of the most widely researched components of the diet, and its effect on digestion remains a growing area of research, the researchers noted.
