An article in the Journal of Human Nutrition and Dietetics notes that some studies show that commercially available detox diets may improve the way a person’s liver removes toxins from their body. However, the article also highlights that these studies had flawed methodologies and small sample sizes.
According to the United States Department of Agriculture (USDA), the fruits in a smoothie will contain more fiber than drinking just the juice of a fruit. USDA also note that most people in the U.S. do not consume enough fiber.
According to the Office for Disease Prevention and Health Promotion , three-quarters of people in the United States do not consume enough fruit and vegetables. Consuming drinks containing fruits and vegetables as part of a balanced diet may be a good way of helping a person get the nutrition they need.
Detoxification does have a basis in medical science. Doctors will often use it when a person has an addiction to certain drugs that are causing them harm.
Many people combine fruits and vegetables in their smoothies. This can be an excellent way of making vegetable smoothies taste good, while not overloading a fruit smoothie with too much sugar.
For example, a lemonade cleanse detox drink, containing lemon juice, maple syrup, and cayenne pepper, sounds healthful, but it contains relatively few nutrients and is high in sugar, which most people should try to reduce .
