Jeffrey M. Smith

A variety of American organic food companies see Smith "as a champion for their interests", and Smith's supporters describe him as "arguably the world's foremost expert on the topic of genetically modified foods". In contrast, Michael Specter, writing in The New Yorker, reported that Smith was presented as a "scientist" on The Dr. Oz Show despite his lack of any scientific experience or relevant qualifications. Bruce Chassy, a molecular biologist and food scientist, wrote to the show arguing that Smith's "only professional experience prior to taking up his crusade against biotechnology is as a ballroom-dance teacher, yogic flying instructor, and political candidate for the Maharishi cult’s natural-law party." Jon Entine, an author and science journalist, accused Smith of being "an activist with no scientific or medical background" and said that Smith's views amount to "near-hysterical criticism".

Smith was a Natural Law Party member in 1996 and participated in a TM-Sidhi program yogic flying demonstration in Des Moines, Iowa. In 1998 he became the party's candidate for U.S. Congress in Iowa’s First District to raise awareness about GMOs. Smith received less than 1% of the vote, losing to Republican Jim Leach. Smith worked for several years as a marketing consultant and nonprofit marketing advisor.

Smith has opposed the use of genetically modified foods since they were introduced in the 1990s. As of 2000, Smith was the spokesperson and vice president for the accredited genetically modified organism (GMO) testing company, Genetic ID. Smith authored the books Seeds of Deception in 2003 and Genetic Roulette in 2007. In 2012 Smith directed and produced Genetic Roulette, a documentary film narrated by Lisa Oz and critical of genetically modified food. Smith is the founder and current executive director of the Institute for Responsible Technology

Jeffrey Smith grew up in New York City and attended Maharishi University of Management in Fairfield, Iowa in the 1980s.
