Process of extracting juice from fruit or vegetables

Juicing is the process of extracting juice from plant tissues such as fruit or vegetables.

There are many methods of juicing, from squeezing fruit by hand to wide scale extraction with industrial equipment. Juicing is generally the preferred method of consuming large amounts of produce quickly and is often completed with a household appliance called a juicer, which may be as simple as a cone upon which fruit is mashed or as sophisticated as a variable speed, motor driven device. It may also refer to the act of extracting and then drinking juice or those who extract the juice. Juicing is different from buying juice in the supermarket because it focuses on fresh pressed fruits and vegetables. Residential juicing is often practiced for dietary reasons or as a form of alternative medicine. Becoming first popular in the early 1970s, interest in juicing has since increased. Films such as Fat, Sick and Nearly Dead, Food Matters, and Hungry for Change have increased the sales of juicers. In America, juicing was popularized by Gayelord Hauser, Jay Kordich and Norman W. Walker.

The American Journal of Public Health proposed that the Healthy Hunger Free Kids Act of 2010 in the United States eliminate 100% fruit juices since it has been linked to childhood obesity, and substitute instead with whole fruits. Juicing removes the fiber content of the fruit or vegetable, and the full benefits of the plant is thus not experienced. Re adding fiber to the juice cannot be equated to whole fruits. Most polyphenols are bound to the plant fibers, and constitute the major portion of dietary polyphenols. There is therefore a marked loss of phytonutrients in consuming fruits and vegetables through the juicing process alone. The American Cancer Society says, "there is no convincing scientific evidence that extracted juices are healthier than whole foods". Juicing may not be the best way to extract all of the nutritional value from fruits and vegetables. One study has shown that when juiced grapefruit was compared with blended, the latter was superior. Smoothies, which are the blending of fruit into juice, not the extraction, leave pulp and seeds within the drink leading to better nutrition.
