Coffee is not just a pick-me-up beverage—in recent years, research has also found that it has potential benefits for the digestive system. A 2023 systematic review and meta-analysis published in the journal Nutrients, which included more than 430,000 participants, explored the association between coffee intake and the risk of irritable bowel syndrome (IBS). The results showed that, compared with non-coffee drinkers, people who drank coffee had a 16% lower risk of developing IBS. This protective effect may be related to the antioxidant and anti-inflammatory properties of components in coffee such as caffeine, polyphenols, diterpenes, and trigonelline. However, the effect of coffee on relieving IBS symptoms varies from person to person, and the study itself has observational limitations. This article will provide a detailed interpretation of this study and explore the possible effects of coffee on gut health. [more…]
