Detoxification programs are based on the idea that the body functions poorly when harmful substances build up in the body. Proponents of detoxification attribute a wide range of symptoms, from fatigue and headaches to allergies, sinus problems, bloating, weight gain, and dull skin and hair, to toxin exposure and build up.
There is no official definition of what constitutes a detoxification program, but the general idea is to cleanse the body of damaging substances, which can include air and water pollutants, pesticides, herbicides, solvents, and other industrial and agricultural chemicals. Most programs recommend people also avoid alcohol caffeine, sugar, artificial sweeteners, and food additives.
Many supporters of detoxification acknowledge the lack of scientific evidence behind the approach, but point out that people often report increased energy, clearheadedness, and a general feeling of well-being afterwards. When approached correctly, advocates claim a good detoxification program can jumpstart weight loss, identify food sensitivities, increase energy, and empower people to adopt healthier eating and lifestyle habits. Juicing programs where a person fasts but continues to drink nutrient-rich raw juices are thought to provide energy and help cleanse the colon and liver.
There is little or no scientific evidence to support claims that the approach improves health, and the symptoms for which detox programs are prescribed is so vague that it’s often impossible to know the cause or whether detoxification really is a cure. Further, some practices related to detoxification, such as colonics, may affect a person’s electrolyte balance, which has caused some doctors to warn against it. Another approach for detoxification, taking laxative herbs, has been reported to disturb healthy digestive tract bacteria needed for digestion and immunity, and cause loss of important minerals, such as sodium, potassium, and magnesium.
If used with care, detoxification programs may help you feel better and get health habits back on track. Many of the safest practices simply involve eating foods that are well-known to support a healthy digestive system and colon, or to stimulate bile production (a sign your liver is working well) in everyone. Use the following tips to decide if and when detoxification is right for you.
