GUTIERREZ-HERVAS, Ana; GARCIA-SANJUAN, Sofía; GIL-VARELA, Sandra  e  SANJUAN-QUILES, Ángela. Relationship between dietary omega-3/omega-6 fatty acids and inflammatory bowel disease: Scoping Review. Rev Esp Nutr Hum Diet [online]. 2019, vol.23, n.2, pp.92-103.  Epub 29-Jun-2020. ISSN 2174-5145.


Inflammatory bowel disease (IBD) includes ulcerative colitis (UC) and Crohn’s disease (CD). It is believed that diet fats can influence the development of this disease. Objective: To analyze how the content of omega-3 and omega-6 naturally present in the diet is related to the IBD process, both in its appearance and in its remission period.

Material and Methods

Data sources: The databases Scopus and PubMed were searched. Eligibility criteria: Studies published between 2007 and 2017, in Spanish and English, quantitative and qualitative design on the topic of study were included. Studies on drugs or supplements, animals and diet in other pathologies were excluded. Evaluation of studies: The studies were evaluated through the CASPe Guide and the objectives of the Scoping Review design.


A total of 14 articles were included.


There is evidence that consumption of omega-3 and omega-6 may influence the development of IBD. Although there are no defined dietary recommendations for people with IBD, it would be essential to create a dietary guide for the control of this pathology.
