Hi - Your English is quite good. I wouldn't have known it was a second language for you if you hadn't mentioned it.
I agree with what Intothewild said. Body Odor is caused by toxicity in the body, and detoxification is the best way to get rid of it. You'd be wise to start with eliminating junk foods and transitioning to a healthy, high-fiber diet. The next step is colon cleansing. After that, you can do kidney and liver cleansing. To learn more about this, read "The Detox Book" by Bruce Fife, ND.
