You need to improve your detox potential by following a liver cleansing diet for two weeks, as well as taking supplements that help to cleanse the system. For the first week this means eating lots of fresh fruit, vegetables and whole-foods such as rice, beans, fish and the like, and staying completely off meat, dairy products, wheat, tea, coffee and alcohol. The best vegetables to eat are broccoli, Brussels sprouts, cabbage, kale and cauliflower, all of which contain substances called glucosinolates that help to support the liver. Also good are carrots, tomatoes, sweet potatoes and other orange-colored foods that are rich in beta-carotene. Be sure, too, to supplement a good high-strength multivitamin and an antioxidant complex.
