Comment on ‘Experience of Diet in Patients With Inflammatory Bowel Disease: A Thematic Synthesis of Qualitative Studies’

Inflammatory bowel disease (IBD) is a chronic condition that can significantly impact quality of life due to gastrointestinal symptoms and related complications. As dietary factors play a central role in disease management, a recent systematic review published in the Journal of Clinical Nursing examined the dietary experiences of patients with IBD (Xiong et al. 2024). While the study provides valuable insights into patient perspectives, several limitations must be addressed to improve our understanding of the role of diet in IBD management and to inform clinical practice. First, the qualitative approach of the review is beneficial in capturing the personal experiences of patients. However, reliance on patient-reported data introduces potential bias. Patients' experiences and perceptions are influenced by their individual disease severity, socio-economic background and psychological state. In addition, the studies included in the synthesis did not explore the experiences of a diverse sample of patients, such as those from different cultural backgrounds or with different disease phenotypes. This limited diversity in patient profiles may bias the findings and reduce their generalisability to the broader IBD population. Future research should consider including a more representative sample of patients to better understand how different subgroups may respond to dietary interventions. Second, while the review highlights the short-term effects of dietary changes, it fails to address the potential long-term consequences of restrictive dietary patterns in IBD patients. Chronic dietary restriction can lead to nutritional deficiencies, including calcium, iron and zinc, which are essential for maintaining overall health and preventing comorbidities such as osteoporosis and anaemia. In addition, the psychological effects of prolonged dietary restriction, such as food-related anxiety and the development of disordered eating behaviours (e.g., ARFID), are not well understood. These factors may negatively impact patients' quality of life and disease outcomes, making it important for clinicians to balance dietary changes with nutritional needs. One of the most striking limitations identified in the review is the lack of adequate professional support for dietary management in IBD. Patients reported receiving limited dietary advice from healthcare professionals, and the advice they did receive was often inconsistent and not tailored to individual needs. This gap in support is concerning given the complexity of IBD and the potential risks associated with poorly managed diets. Nurses, dietitians and other healthcare professionals should play a more proactive role in providing personalised dietary advice and psychological support. In addition, the review does not emphasise the need for interdisciplinary collaboration to address the multifaceted nature of IBD management, including dietary, psychological and social aspects. More emphasis should be placed on empowering healthcare teams to work together to provide comprehensive care. Finally, the review briefly mentions the impact of food cravings on dietary adherence, but this is an underexplored area. The psychological and neurobiological factors that drive food cravings and the hedonic pleasure associated with eating are critical to understanding why some IBD patients may have difficulty adhering to dietary restrictions. Studies have shown that restrictive diets can lead to intense food cravings, which may lead to the failure of dietary interventions. Addressing food hedonism and craving through cognitive-behavioural interventions and behavioural therapy may improve dietary adherence and reduce the emotional distress associated with food restriction.
