Her movement became popular because of the increased use of pesticides, chemicals, additives and fertilizers to increase food production. Davis wrote a series of four books, starting with a cookbook in 1947, that ultimately sold over 10 million copies in total. Although her ideas were considered somewhat eccentric in the 1940s and 1950s, the change in culture with the 1960s brought her ideas, especially her anti-food processing and food industry charges, into the mainstream in a time when anti-authority sentiment was growing. She also contributed to, as well as benefited from, the rise of a nutritional and health food movement that began in the 1950s, which focused on subjects such as pesticide residues and food additive. During the 1960s and 1970s, her popularity continued to grow, as she was featured in multiple media report.
