The Institute for Scientific Information on Coffee has produced a new article exploring the common misconceptions surrounding coffee consumption and digestive health. The ‘mythbuster’ highlights that there is no evidence to suggest that coffee consumption is associated with a range of digestive health issues, such as acid reflux, dyspepsia, IBS or constipation.
Key research highlights include:
- There is no evidence to suggest that coffee consumption causes acid reflux. In fact, it is suggested that common causes of acid reflux are the consumption of spicy or fatty food and overeating [1,2,3,4]
- One study found that 38% of people thought coffee was a cause of dyspepsia, however no association between drinking coffee and this condition have been found [6,7,8,9]
- Recent research suggests coffee does not lead to dehydration and contributes to daily fluid intake 
- Coffee can be enjoyed by those who suffer from disorders such as IBS, gastritis, Crohn’s Disease, colitis and ulcers, as there is no indication that it influences these disorders.
Dr. Patricia MacNair, Trust Practitioner at The Royal Surrey County Hospital, UK, commented on the mythbuster: “”Approximately 1 in 3 adults in the European Union (more than 150 million) are affected by digestive health problems such as dyspepsia, IBS or constipation.
Many of my patients with digestive complaints ask me if their coffee consumption is the issue and if they should cut coffee out of their diet. It is true that some individuals who suffer GI problems may choose to avoid certain foods or drinks to manage their symptoms, and this may include coffee.
However, the research available shows that there is no evidence to suggest a link between coffee consumption and gastric health problems.”
