Key clinical point: American adults with higher dietary zinc intake were at a lower risk for migraine, demonstrating an inverse association between dietary zinc intake and migraine.
Major finding: The risk for migraine was significantly lower among participants in the highest (≥15.8 mg/day) vs lowest ( ≤5.9 mg/day) quintile of dietary zinc intake (adjusted odds ratio [aOR] 0.70; P = .029) and remained low among participants with dietary zinc intake of at least 6.0-8.4 mg/day (aOR 0.73; P = .004) .
Study details: This cross-sectional study included 11,088 adults with or without migraine from the US National Health and Nutrition Examination Survey (1999-2004).
Disclosures: This study was supported by grants from the National Natural Science Foundation of China. The authors declared no conflicts of interest.
