Don't eat this if you're taking that

"Fernstrom provides an easy to use guide for anyone taking a medication--short term or long term--and foods to avoid that can interfere with the action of the medication. Small diet changes with big health payoffs! An added bonus in each chapter is a "Dietary Supplements Alert" box, providing the most up to date information on interactions with vitamins, minerals and other dietary supplements."--Provided by publisher.
