I am using plavix 75mg, hydroxyurea 500mg, and allopurinol 300mg daily. is there a special diet to use when taking these tablet combinations? what foods shall i avoid and what foods are beneficial to use ? thanking you for your assistance ?

No foods interact with the medications you take; however, because allopurinol is used to treat high serum uric acid so it will be counter-effective if you continue to eat foods with high uric content such as most kinds of seafood, red meats, lentils, fava beans or cauliflower, spinach, or asparagus, etc. You can googles for the foods with high uric content and certain fruits lower uric acid.
