Adelle Davis (25 February 1904 – 31 May 1974) was an American author and nutritionist, considered "the most famous nutritionist in the early to mid-20th century." She was as an advocate for improved health through better nutrition. She wrote an early textbook on nutrition in 1942, followed by four best-selling books for consumers which praised the value of natural foods and criticized the diet of the average American. Her books sold over 10 million copies and helped shape America's eating habits.

Nutrition is a young subject; it has been kicked around like a puppy that cannot take care of itself. Food faddists and crackpots have kicked it pretty cruelly. . . . They seem to believe that unless food tastes like Socratic hemlock, it cannot build health. Frankly, I often wonder what such persons plan to do with good health in case they acquire it.
