  1. This is the first large, prospective study of dietary fatty acid intake in ALS and a much more robust confirmation of the association seen in two prior retrospective case-control studies (Veldink et al., 2007; Okamoto et al., 2007). The authors also commented on the recent, apparently contradictory finding by Yip et al. (Yip et al., 2013) that showed that dietary eicosapentaenoic acid (EPA), a marine-derived fatty acid, did not improve survival in the SOD1 ALS mouse model. One possible explanation for this discrepancy is the different kinds of fatty acids used. The marine-derived omega-3 fatty acids (like EPA) used in the Yip paper were only marginally significant in the Fitzgerald JAMA Neurology study; Fitzgerald and colleagues found that plant-derived fatty acids like alpha-linolenic acid were more effective. However, as we have learned from the Alzheimer's experience with omega-3 supplementation, even a strong epidemiological association may not translate into an effective treatment.
