A recent narrative review highlights the promising role the Mediterranean diet may play in managing inflammatory bowel disease (IBD). The review explores key nutrients within this dietary pattern that might offer particular benefits to individuals afflicted by IBD. Conducted by experts in IBD and nutrition, the study received funding from the European Crohn’s and Colitis Organization fellowship 2024.
The Mediterranean diet, renowned for its health benefits, appears to possess anti-inflammatory properties potentially beneficial for those with IBD. Among its diverse components, pigments such as those found in red wine and a variety of foods are believed to aid in reducing inflammation. This comprehensive dietary pattern includes seafood and nuts, both of which are subjects of debate regarding their impact on IBD development.
The review authors focused on data from a specific timeframe and utilized only one database, exclusively including studies published in English. This approach has led to some limitations in the scope of data presented, with the majority derived from preclinical studies due to the scarcity of clinical research in this area. As Berkeley Limketkai, MD, PhD, noted:
“Most of the information presented is drawn from preclinical data due to the dearth of clinical studies.” – Berkeley Limketkai, MD, PhD
In examining the various elements of the Mediterranean diet, the review delves into the potential benefits conferred by seafood, nuts, and red wine. However, a case-control study within the report suggests a possible link between these components and the development of IBD, highlighting the complexity and need for further research. While these foods are part of the Mediterranean diet, they are not exclusive to it, as emphasized by Limketkai:
“While each of these purportedly beneficial nutrients/food types are components of the Mediterranean diet, they are not unique to the diet.” – Berkeley Limketkai, MD, PhD
Despite these nuances, the review offers an evidence-based rationale for considering the Mediterranean diet as beneficial for individuals with IBD. It suggests that this dietary pattern supports overall health and well-being, potentially through its effects on the gut microbiome. However, the precise mechanisms by which it aids gut health remain unclear.
The authors' examination provides a detailed exploration of how various components contribute to the diet's anti-inflammatory effects. This analysis reinforces existing knowledge while offering insights into specific dietary elements that may be advantageous for managing IBD. As Limketkai summarized:
“As the review summarizes existing data and is not a research study per se, it does not specifically add to what is already known about diet and IBD. The evidence presented nonetheless reinforces the benefits of the Mediterranean diet while diving into detail about the components that confer the Mediterranean diet its anti-inflammatory effects.” – Berkeley Limketkai, MD, PhD
