Juice Detoxification

Juice detoxification, often called a juice cleanse, is a short-term eating pattern in which fresh fruit and vegetable juices replace some or all regular meals. It is promoted as a way to reset habits, take in a concentrated serving of plant nutrients, and give your digestion a break.

Programs vary. Some are a day or two of juices, and others run longer. A practitioner may start with a health review, suggest a juice plan suited to your goals, and offer guidance on how to ease back into regular eating afterward. Many people drink several juices through the day, sometimes with broth or water, and may feel lighter, hungry, or tired.

People use juice programs to start new habits, increase their intake of fruits and vegetables, and feel a sense of freshness and renewed energy. Some hope to support digestion or skin. Practitioners often describe the cleanse as a short reset, not a lasting solution.

The evidence for detoxification is limited. Fruits and vegetables are valuable sources of vitamins and phytonutrients, and eating more of them is linked with better health. However, there is little research showing that juices remove toxins, because the liver and kidneys already do that work. Juicing also removes most of the fiber and can supply a lot of sugar.

Speak with your doctor first if you have diabetes, kidney disease, heart conditions, or take medication, particularly blood thinners. People who are pregnant, have a history of disordered eating, or have a weakened immune system should usually avoid restrictive cleanses. A balanced, varied diet is generally a more sustainable path to wellbeing.

Fasting and restricted diets for spiritual or health reasons are old and found in many cultures, but the idea of using fresh juices came mostly from early twentieth-century Europe and North America. German physician Otto Buchinger (1878 to 1966) developed a supervised fasting program built around broth and diluted juices, and his clinic became a model for later fasting centers. In the 1930s, physician Max Gerson, who emigrated to the United States in 1936, included large amounts of fresh juice in his dietary program.

The figure most often linked to the juicing movement is Norman Walker (1886 to 1985), an American raw food advocate. In 1936 he published Raw Vegetable Juices and introduced a mechanical juicer he called the Norwalk, and a revised edition of his book appeared in 1978 as Fresh Vegetable and Fruit Juices. Ann Wigmore and later television promoters such as Jay Kordich helped bring juicing into American homes, especially in the 1980s and 1990s.

From the 2000s, commercial juice bars and packaged cleanse programs made short juice diets a mainstream wellness trend. Today there is no single standard program or credential, and approaches range from a day or two of juices to longer plans. The claim that juices remove toxins is promotional language rather than an established finding, and the liver and kidneys already clear waste.
