The prevalence of inflammatory bowel disease (IBD) has been rising year by year. Crohn's disease (CD) and ulcerative colitis (UC) are increasingly diagnosed in both pediatric and adult populations. Since the early 21st century, IBD has become a global health problem. Despite the advances in medical treatment, clinical remission and mucosal healing are still not achieved in many patients. The cause is likely rooted in the fact that the immune system and microbiome of genetically susceptible, with the environment also playing a role, fail to provide an appropriate response, which subsequently leads to chronic inflammation of the gut. Recently increasing evidence has emerged that one of the major environmental factors that play a role in the onset and course of the disease is the diet. This leads to the conclusion that it can be used as part of the strategy to reduce clinical symptoms and intestinal inflammation.
The aim of this article is to analyze the available information in the field of personalized dietary patterns with an accent on their level, focus, and scope. The ever-changing evidence for modifiable dietary approaches will give us the opportunity to walk the path from generic advice on a healthy diet to truly personalized dietary plans tailored to meet the needs of each individual patient with IBD.
