Low fat dietary intervention with omega-3 fatty acid supplementation in multiple sclerosis patients.Weinstock-Guttman B, Baier M, Park Y, Feichter J, Lee-Kwen P, Gallagher E, Venkatraman J, Meksawan K, Deinehert S, Pendergast D, Awad AB, Ramanathan M, Munschauer F, Rudick R.Baird Multiple Sclerosis Center for MS Treatment and Research, s Neurological Institute, State University of New York, 100 High Street, Buffalo General Hospital-E2, Buffalo, NY 14203, USA.Objectives: To determine whether a low fat diet supplemented with omega-3 positively affects quality of life (QOL) in relapsing-remitting MS (RRMS) patients. In this 1-year long double-blind, randomized trial, patients were randomized to two dietary interventions: the "Fish Oil" (FO) group received a low fat diet (15% fat) with omega-3 FOs and the "Olive Oil" (OO) group received the AHA Step I diet (fat 30%) with OO supplements. The primary outcome measure was the Physical Components Summary Scale (PCS) of the Short Health Status Questionnaire (SF-36). Additional measures using MS specific QOL questionnaires, neurological status and relapse rate were obtained. Results: 31 RRMS patients were enrolled, with mean follow up over 11+/-SD 2.9 months. Clinical benefits favoring the FO group were observed on PCS/SF-36 (P=0.050) and MHI (P=0.050) at 6 months. Reduced fatigue was seen on the OO diet at 6 months (P=0.035). The relapse rate decreased in both groups relative to the rates during the 1 year preceding the study: mean change in relapse rate in the FO group: -0.79+/-SD 1.12 relapses/year (P=0.021) vs. -0.69+/-SD 1.11 (P=0.044) in the OO group. This study suggests that a low fat diet supplemented with omega-3 PUFA can have moderate benefits in RRMS patients on concurrent disease modifying therapies.PMID: 16099630 [PubMed - in process]
