Despite significant advances in genetics, Inflammatory Bowel Disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is still a complex and multigenetic disease whose incidence is increasing worldwide. Although drug-based therapies are progressing, new evidence shows that nutritional approaches play a paramount role in prevention and therapy [1].In this editorial, we emphasise recent evidence 4 and support for a change in paradigm toward integrative dietary strategies in IBD management.Several researchers have suggested that maternal prenatal diet may be linked to the impact on the offspring's gut health [2]. Anneberg OM et al. analyzed data from 60,274 singleton mother-child dyads recruited in the Danish National Birth Cohort to investigate the relationship between maternal intake of foods and dietary nutrients during pregnancy and the risk of pediatric onset of IBD in offspring, including CD and UC. In this study, frequent maternal intake of organic eggs and dairy products in pregnancy were associated with the potential risks of paediatric-onset CD. No significant relationship was found for UC; however, these findings support a potential role of prenatal diets in long-term gut health in children. Based on this concept, dietary patterns in early adulthood have also been studied in relation to IBD risk. Recent studies have suggested that high consumption of red meat, particularly pork, beef, and lamb, may exacerbate colonic inflammation by altering gut microbiome structure and triggering pro-inflammatory immune reactions [3].Zhang Y et al. relapse risk of UC. In their study, the researchers found that a high consumption of red meat, approximately 100 grams per day, was associated with a 65% increased risk of UC development. Based on very low-certainty evidence, high red meat intake may be associated with an increased risk of UC. Nevertheless, the evidence is insufficient to attribute a definite association between the intake of red or processed meat and relapse in UC; the sparse data suggest that processed meat may not increase UC risk to the same extent as red meat. Since diet interacts directly with the gut, more studies are exploring the protective effects of specific probiotic supplements in altering the gut microbiota for improved health outcomes.Probiotics have been effective in the past in reducing antibiotic-associated diarrhoea and infectious diarrhoea [4].Wang M et al. assessed the effect of a complex probiotic product on post-weaning diarrhoea in weanling piglets. In the present trial, piglets supplemented with selected strains of probiotics in their diet had significantly less diarrhoea. These beneficial effects were primarily due to the enhanced barrier, robust defense system, and lower pathogen load, along with an enriched population of friendly microbes. It is worth noting that the probiotic product, which includes Bacillus subtilis and Bacillus licheniformis, may benefit intestinal health and provide a potent, antibiotic-free method for controlling diarrhoea in piglets. Probiotics for IBD-related diarrhea also appear promising, although strain-specific effects and patient variation should be considered. Likewise, the role of micronutrients, including iron, has also been studied for their twofold function in meeting physiological requirements as well as potentially modulating intestinal inflammation. Iron replacement is necessary for the treatment of anaemia in patients with IBD. However, its effect can vary slightly depending on the form and dose. Redundant iron may exacerbate intestinal injury and inflammation, whereas certain formulations can maintain the efficacy of probiotics and enhance intestinal barrier integrity [5]. In a study by Wang S et al., the small intestine is also involved in experimental colitis, and its iron content contributes to the Dextran Sulphate Sodium (DSS)-induced damage/regeneration of the intestines. These results draw attention to the necessity for more careful thought regarding iron supplementation protocols in clinical settings taking into account several factors. In summary, these observations underscore the necessity for individualized iron supplementation strategies that take into account nutritional needs in light of the potential risk of exacerbating gut inflammation. In addition to these micronutrients, integrative therapies that involve pharmacotherapy and nutrition support have also been investigated. Huang C et al. assessed the impact of PEN as adjunct therapy to infliximab in CD patients. In the 54-week study, 176 patients were tracked, and PEN was administered as an inducement and maintenance in 77 of them. The findings showed that when added to infliximab treatment, PEN is able to significantly enhance short-term clinical response and sustained endoscopic remission. Such an integrative approach could work by minimizing drug efficacy loss and mucosal healing, offering a strong rationale for the synergistic application of pharmacological and nutritional treatments in CD.Consistently, Traditional Chinese Medicine (TCM) is being applied in drug discovery and disease treatment due to its wide range of biological activities, low toxicity, and few side effects.A number of prior studies have identified therapeutic effects for certain TCM formulas in IBD. Among these, honeysuckle (Lonicera japonica) has been developed as a well-known botanical for IBD therapy. Its bioactive components, including chlorogenic acid and luteolin, achieve anti-inflammatory, antioxidant, and microbiota-modulating effects. In addition, exosomes These alterations might be associated with the decreased production of tryptophan-derived indole metabolites, enhanced function of enteric glial cells (EGCs), and inhibition of the aryl hydrocarbon receptor (AHR)/CYP1A1 axis. Special attention should be focused on tryptophan metabolism and the manipulation of AHR and regulatory T cells as potential options for novel IBS treatment strategies. In this setting, nutritional interventions, such as dietary exclusions, specific supplementation, and microbiota-directed therapies, are emerging and changing the therapeutic scenario. The combination of these approaches with traditional therapies may provide the framework for a personalized, efficient, and durable management of IBS. To summarize the evidence mentioned in this Editorial more clearly, we prepared a Table of evidence that includes the main nutritional interventions studied in relation to IBD (Table 1).In this systematic synthesis, and accompanying graphical abstract, we present the evidence for, against, or supporting an effect of dietary factors on the onset, progression, or treatment of IBD to provide a more auditable evaluation that highlights the heterogeneity and quality differences between studies found Legend Figure
