you are going about things the wrong way. you need to change your lifestyle completely, basically if you base your diet on good stuff you will be as right as rain. i believe and this is only my opinion but i believe the best way to go.....base your diet on raw or lightly cooked vegetables and fruit. add in pasta etc. no meat or dairy which our bnodies cant really handle (hence coronary heart disease and cancer being the biggest killers in the west) and excercise naturally and be happy and your body will thank you for it. mine does.
