John Steven "Jay" Kordich (August 27, 1923 – May 27, 2017) was an American author and advocate of juicing and juice fasting. Kordich was best known as the "Juiceman" and the "Father of Juicing" in the United States.
|Died||May 27, 2017 (aged 93)|
|Occupation||Author, advocate of juicing|
Kordich played college football for the University of Southern California (USC) in 1948 and was drafted in the 22nd round of the 1949 NFL draft by the Green Bay Packers. Before Kordich could sign with the Packers, he was diagnosed with inoperable bladder cancer.
Kordich authored The New York Times best seller The Juiceman's Power of Juicing, first published in 1992. He was involved in advertising a series of juicers, including the Juiceman Juicer. He lectured on the subject and appeared in television infomercials for the Juiceman Juicer. In 2011, Kordich developed the Jay Kordich PowerGrind Pro juicer.
In 1992, Consumer Reports tested Kordich's Juiceman II extractor and concluded that other competitive models were easier to clean, cheaper, and worked better. Kordich's health claims in regard to juicing have been disputed by medical experts. For example, Kordich stated that he was influenced by the Gerson diet and was cured from cancer when he was 20 by consuming 13 glasses of apple and carrot juice each day.
Stephen Barrett of Quackwatch noted that Kordich made far-fetched, nonsensical, and unproven health claims about juicing. These included his belief that uncooked foods flush the body of toxins (detoxification), and that juicing can treat many illnesses such as anemia, anxiety, arthritis, gallstones, impotence, and heart disease.
On May 27, 2017, Kordich died at 8:30 pm due to breathing problems.
