There was no evidence of an association between overall diet quality and risk of developing multiple sclerosis (MS) among women, according to a recent study. >185,000 women in the Nurses’ Health Study (NHS) and Nurses’ Health Study II (NHSII) completed semi-quantitative food frequency questionnaires every 4 years. There were 480 MS incident cases. Diet quality was assessed using the Alternative Healthy Eating Index-2010 (AHEI-2010), Alternate Mediterranean Diet (aMED) index, and Dietary Approaches to Stop Hypertension (DASH) index. Researchers found:
- None of the dietary indices, AHEI-2010, aMED, or DASH, at baseline was statistically significantly related to the risk of MS.
- The principal component analysis identified “Western” and “prudent” dietary patterns, neither of which was associated with MS risk (HR, top vs bottom quintile: Western, 0.81 and prudent, 0.96).
- When the analysis was repeated using cumulative average dietary pattern scores, the results were unchanged.
