Sulfites & Migraine
Andrew L. Waterhouse says ‘there is no medical research data showing that sulfites cause headaches. (See: http://waterhouse.ucdavis.edu/whats-in-wine/sulfites-in-wine): There is something in red wine that causes headaches, but the cause has not yet been discovered. To avoid these common headaches, try drinking less wine, and drink with food. If you think sulfites are causing your headache, try eating some orange-colored dried apricots. If that [fails to] induce a headache sulfites are not the likely culprit [because] these bright colored dried fruits typically have 2000 mg/kg sulfites, so a two ounce serving (56 gm) should contain about 112 mg sulfites. It is certainly possible that sulfites cause headaches, but as noted above, there is no data available.’
