Migraines from food after the use by date sounds like a strong psychosomatic effect. If you'd say upset stomach or diarrhea ok, but I'm not sure how it would trigger a migraine except psychologically.
I'm not saying this to be dismissive. These effects can be incredibly strong, I could not eat pork cutlets for years after I had an extremely strong migraine when I ate one. After my body associated the smell and taste with it and noped out every time I got close to one.
