Fasting juice, also known as juice cleaning, is a fad diet in which a person only consumes fruit and vegetable juices while abstaining from solid food consumption. It is used for detoxification, an alternative drug treatment, and is often part of detox diets. The diet can usually last two to seven days and includes a number of fruits and vegetables and even herbs that are not among the juices that are usually sold or consumed in the average Western diet.
This diet is sometimes promoted with incredible and unsubstantiated claims about the health benefits.(1)
Catherine Collins, dietitian at St George's Hospital Medical School in London, England, states: "The concept of & # 39; detox & # 39; is a marketing myth rather than a physiological entity. The idea that an avalanche of vitamins, minerals and laxatives has been taken over a period of 2 to 7 days can be a long-term benefit for the body, is also a marketing myth. "(2)
Detox diets, depending on the type and duration, are potentially dangerous and can cause various health problems, including muscle loss and unhealthy fat recovery after the detox ends.(3)
Juice mixes containing grapefruit juice can have a negative impact on some prescription drugs.(4)
