Editorial: Nutrition management puzzle in IBD

The etiology of IBD is not fully understood, but it is often complex and involves several different factors, such as genetic, immunological, environmental, and gut microbiota dysbiosis [1,2]. Currently, Western countries are characterized by a rapid incidence of IBD, ranging from 12 to 26 per 100,000 people [3].Due to the symptoms of the disease, in addition to pharmacological and surgical treatment, proper nutrition is a very important aspect that supports basic therapy.During remission, a healthy diet that avoids individual nutritional risk factors is recommended for IBD patients, while according to the ESPEN guidelines, there is no diet that accelerates remission in IBD [4]. Wei et al. analyzed the effect of certain diets on specific parameters in patients with IBD, including C-reactive protein (CRP) levels, albumin (ALB) levels, and disease activity assessed endoscopically using the Mayo Endoscopic Score (MES). The authors observed that the combination of a low-FODMAP diet with enteral nutrition significantly reduced CRP levels compared to a standard diet, a low-residue diet, and a low-FODMAP diet without modification. Similarly, these two diets proved to be the most effective in increasing albumin levels. In terms of endoscopic remission, the researchers observed the best results after following a diet based on IgG testing (IgG-ED). There is no universal diet for IBD, and different clinical goals require different nutritional approaches.
