6 LOVE YOUR LIVER synthetic dyes, pesticides, and fertilizers you ingest. Choosing wild-caught fish low in mercury can help you avoid both the heavy metals and the pesticides commonly found in farm-raised fish. It’s also important to drink purified water to sidestep chlorine, lead, fluoride, and other chemicals often found in municipal water supplies. The Fiber Factor The importance of fiber to the detoxification process cannot be overstated. After your liver has processed a toxin, it dumps it into the digestive tract. If enough fiber is present, it shuttles the toxin out of the body with your next bowel movement. If not, these toxins can be reabsorbed into the blood stream and the liver has to deal with them again. Whole grains such as quinoa or millet are a great source of fiber, as are many fruits and vegetables. Using ground flax is another effective way to ensure you are getting enough fiber. If eating enough fiber is not possible or if you are irregular or constipated, consider using a fiber supplement. Avoid These! Many drugs can be harmful to the liver.A particular concern is over-the-counter acetaminophen (Tylenol), and cold and pain remedies that contain this pain reliever. Commonly prescribed medications including statins, acid blockers, psychiatric drugs, certain antibiotics, and antifungals are notorious for causing liver problems.
