Yup! That's why we have livers! If your's is working properly, you shouldn't worry about "toxins".
Mom, I am a great devotee of naturopathy BUT they are like religious zealots with their dedication to all things "natural". You have to discern through the malarky what is viable information and what is, well, propaganda.
I adhered to a macrobiotic diet for two years, which is a diet that the natural health folks extol. That was nearly 20 years ago. Did it help? No. Did it cure me? No. Was is costly and incredibly time-consuming? Yes. Was it sustainable? No.
These "cleanses" that they push are, IMO, alot of hooey. Colon cleansers definatly compromise normal bowel function and are really nothing more than glorified laxatives. Liver cleanses are scary and I would not take anything designed to mess with that organ.
Organic foods are ideal, of course, although one must be careful when buying them because the fine print sometimes contradicts the claim of fully organic. Very few people I know can afford to eat EVERYTHING organic. I try to buy my produce locally from organic farmers but that is the most I can do with my budget.
Juicing, for me, was the kiss of death. I've read your other posts here and I understand you suffer with terrible gas. If you start juicing, you might as well lock yourself in your bathroom with a an industrial exhaust fan and lots of scented candles. You will be tooting more than you ever thought humanly possible.
Hope that helps!
