An old friend you have not seen in over 10 years tells you that she thinks you need to do a liver cleanse. Being an avid reader of alive magazine and a supporter of organic foods, health food stores, and nutritional supplements, you are both shocked and dismayed at her coffee-shop “diagnosis.” After a few depressing hours wondering what your friend was thinking, you consult your alive Encyclopedia of Natural Healing only to discover that you have at least 12 of the most common signs or symptoms of a toxic liver. Advance Warning A poorly functioning liver may not always reveal itself to your doctor during a physical examination or through blood tests collectively called liver-function tests. In fact, it may take years for an unhealthy liver to manifest a disease such as hepatitis or cirrhosis. What kinds of symptoms might warn someone that they need to detoxify their liver before disease actually sets in? While there may be many different health issues or conditions that signal potential liver problems, some of the most common ones include a history of exposure to toxic substances, heavy drug and/or alcohol use, or the pre-existence of various diseases or conditions such as diabetes, high cholesterol, or chronic digestive disorders. A Critical Role What does the liver do, and why would it need to be cleansed? The liver sits in the right upper side of your belly and performs thousands of tasks vital to life. Its most valuable role is detoxifying the body after exposure to or ingestion of harmful foods, chemicals, and microbes. The liver’s role in detoxification is achieved through complex enzyme systems known as phase I and phase II detoxification pathways. These enzyme systems require a number of vitamins, minerals, amino acids, and phytochemicals found in foods to work properly. There are well over 100,000 different toxins found in our food, water, and air, including polycyclic hydrocarbons found in various herbicides and pesticides (such as DDT, dioxins, 2,4,5-T, 2,4-D, and PCBs). The medical profession contributes its share of toxins to our bodies in the form of mercury-containing vaccines, liver-stressing antibiotics, analgesics, narcotics, synthetic hormones, tranquilizers, and thousands of other damaging drugs. In addition to detoxification, the liver is critical for many aspects of digestion (breaking nutrients down) and assimilation (building up body tissues). It stores many essential vitamins (B12, A, D, E, and K) and minerals such as iron and copper. Red blood cells, responsible for carrying oxygen around the body, are also produced in the liver. The Kupffer cells in the liver filter bacteria and small foreign proteins out of the blood and help the body fight infections. Hormones and blood-clotting factors are also metabolized in the liver. With its multitude of biochemical roles, it is easy to see how the liver can get into trouble either as a result of nutritional deficiencies or an overtaxing of its detoxification functions. What can you do to help your liver? Periodic liver cleansing can be of value to even the healthiest of individuals. Diet for a Healthy Liver While there are dozens of different liver cleansing programs, they all include basic dietary changes and some health-enhancing supplements. Drink plenty of water (6 to 12 cups/ 1.5 to 3 litres per day) because water helps the kidneys flush out toxins. Avoid multiple vitamins containing iron and high doses of preformed vitamin A, as these too can stress an unhealthy liver. Regular vegetable-juice fasting with beets, celery, and carrots is ideal, but if juice fasting isn’t possible for you right now, emphasize high-fibre fruits, vegetables, seeds, nuts, and legumes in your diet. Include foods that support the liver detoxification pathways (see sidebar). Avoid animal products (meats, fish, and all dairy products), saturated fats, refined sugar, drugs, and alcohol. Heat It Up Your fat and muscle cells can store up to five grams of toxic environmental chemicals, drugs, and thousands of other poisons. Collectively, these have been termed xenobiotics (chemicals foreign to the body). Some of these are toxic to the liver, the immune system, the nervous system, or the kidneys. Some xenobiotics mimic hormones like estrogen, and some cause cancer.
