@jshdma, Here's some research from 2017:

"In conclusion, our study demonstrates that dietary modification focused on elimination of potentially immunogenic or intolerant food groups has the potential to improve symptoms and endoscopic inflammation in patients with IBD. Dietary change can be an important adjunct to IBD therapy not only to achieve remission but perhaps improve the durability of response and remission. Perhaps for a subset of patients, dietary and lifestyle modification alone may be sufficient to control underlying luminal inflammation. Patients wishing to incorporate dietary therapy should be counseled on options assessed for micronutrient deficiencies and monitored routinely. Integrating and coordinating care with health coaches and registered dieticians can allow for effective education and implementation of dietary modification over time, in accordance with unique patient goals as well. Larger randomized trials are needed to validate these findings and examine the long-term course of patients during reintroduction."
