Michael - I wish I could provide more specifics as well, however without knowing which specific medications you are taking, I'm not able to tell you exactly how they might be metabolized in your body and the list of foods in our database is quite large. In addition, each person is unique and what one may experience, may not be the case for another.
The pharmacist or your Dr. should be able to provide you with all nutrient/food/drug interactions that are relevant to your medications. They make specific books that cover most meds available. One of the biggest known interactions is grapefruit with statins. I would avoid this citrus fruit while taking your medications. Pomegranate and its juice is another one that is believed to interfere with statins. http://www.uspharmacist.com/content/c/10374/
Also, keep in mind interactions among medications and supplements (vitamins, herbs, etc.). When looking up supplements on the Internet to see if any contraindicatons are noted, be mindful of whose site it is so that your information comes from a credible source. Two that I'd recommend are:
For herb/drug interactions - http://www.mskcc.org/cancer-care/herb/chia
For herb/supplement/drug interactions - http://www.integrativeinc.com/Resources/Drug-nutrient-interactions.aspx
Hope that helps!
