This study indicates that there is very little scientific evidence to prove that the Paleo diet is effective for treating IBD. It notes that eliminating carbohydrates might not be beneficial in all cases of IBD. It also cautions that the Paleo diet might cause Vitamin D deficiency which might harm people with an autoimmune disease like IBD.
Diet and Inflammatory Bowel Disease: Review of Patient-Targeted Recommendations
Jason K. Hou, Dale Lee, and James Lewis
2014
Patients have strong beliefs about the role of diet in the cause of inflammatory bowel disease (IBD) and in exacerbating or alleviating ongoing symptoms from IBD. The rapid increase in the incidence and prevalence of IBD in recent decades strongly suggests an environmental trigger for IBD, one of which may be dietary patterns. There are several pathways where diet may influence intestinal inflammation, such as direct dietary antigens, altering the gut microbiome, and affecting gastrointestinal permeability. However, data that altering diet can change the natural history of IBD are scarce, and evidence-based dietary guidelines for patients with IBD are lacking. Patients, therefore, seek nonmedical resources for dietary guidance, such as patient support groups and unverified sources on the Internet. The aim of this review is to identify patient targeted dietary recommendations for IBD and to critically appraise the nutritional value of these recommendations. We review patient-targeted dietary information for IBD from structured Internet searches and popular defined diets. Patient-targeted dietary recommendations focus on food restrictions and are highly conflicting. High quality dietary intervention studies are needed to facilitate creation of evidence-based dietary guidelines for patients with IBD.
