Daisie Adelle Davis (25 February 1904 – 31 May 1974), popularly known as Adelle Davis, was an American author and nutritionist who became well known as an advocate for specific nutritional stances such as unprocessed food and vitamin supplementation. She gained prominence in the 1960s and 1970s with widespread media attention and became the most recognized nutritionist in the country. Despite her popularity, she was heavily criticized by her peers for many recommendations she made that were not supported by the scientific literature, some of which were considered dangerous.

Adelle Davis was born to Charles and Harriette Davis in Lizton, Indiana, USA, on February 25, 1904. She studied Home Economics at Purdue University from 1923 to 1925 and received her Bachelor of Arts degree in Household Studies from the University of California at Berkeley in 1927. After receiving dietetic training at Bellevue and Fordham Hospitals in New York City, she supervised nutrition for Yonkers Public Schools as well as consulted as a nutritionist for New York obstetricians.

From 1931 through 1958, Davis was a private consulting nutritionist in Oakland and Los Angeles, California. She received her Master of Science degree in Biochemistry from the University of Southern California. In October 1943, Davis married George Edward Leisey, and adopted his two children, George and Barbara, though she never had children of her own. She divorced George Leisey in 1953 and married a retired accountant and lawyer named Frank Sieglinger in 1960.
