Juice fasting
Juice fasting, also known as juice cleansing, is a fad diet in which a person consumes only fruit and vegetable juices while abstaining from solid food consumption. It is used for detoxification, an alternative medicine treatment, and is often part of detox diets. The diet can typically last for two to seven days and involve a number of fruits and vegetables and even spices that are not among the juices typically sold or consumed in the average Western diet. The diet is sometimes promoted with implausible and unsubstantiated claims about its health benefits.[1]
History
Juice fasting was popularized in America by Jay Kordich.[2]
Criticisms
Health claims in regard to juice fasting are not supported by scientific evidence.[2][3][4]
Catherine Collins, chief dietician of St George's Hospital Medical School in London, England, states that: "The concept of ‘detox’ is a marketing myth rather than a physiological entity. The idea that an avalanche of vitamins, minerals, and laxatives taken over a 2 to 7 day period can have a long-lasting benefit for the body is also a marketing myth."[5]
Detox diets, depending on the type and duration, are potentially dangerous and can cause various health problems including muscle loss and an unhealthy regaining of fat after the detox ends.[6] A review in The Gale Encyclopedia of Diets, has noted potential risks of juice fasting:
The major risks to health from juice fasts include metabolic crises in patients with undiagnosed diabetes or hypoglycemia; dizziness or fainting due to sudden lowering of blood pressure; diarrhea, which may result in dehydration and an imbalance of electrolytes in the body; and protein or calcium deficiencies from unsupervised long-term juice fasts.[3]
Juice mixes containing grapefruit juice may adversely interact with some prescription drugs.[7]
