There are only a few other food-drug interactions, most of which are of little relevance:
Licorice and cheese with MAO inhibitors (older antidepressants) - hypertensive crisis.
Large amounts of leafy greens and warfarin (anticoagulant) - impaired anticoagulant effect.
Alcohol and metronidazole (antibiotic) - unpleasant hangover like reaction, flushing, headaches.
Ice during oxaliplatin infusion (chemotherapy drug for bowel cancer) - a VERY unpleasant but temporary syndrome of weird sensations in the throat and larynx.
