A handy site for food-drug interactions

The Center for Food-Drug Interaction is a partnership between the University of Florida and Tufts University. They're starting with grapefruit juice, which affects the absorption and effects of several different medications (a small number overall, but still good to know. One of the drugs in the 'strong' category, for example is Diazepam (Valium). Grapefruit juice significantly increases plasma levels of the drug.) So, check them out if you're interested in how your food may affect medication.
