In the field of nutrition the outstanding advance of the 20th century was the discovery and the appreciation of the importance to health of the “accessory food factors”, or vitamins. Various works had shown that animals did not thrive on a synthetic diet containing all the correct amounts of protein, fat, and carbohydrate; they even suggested that there must be some unknown ingredients in natural food that were essential for growth and maintenance of health. But little progress was made in this field until the classical experiments of the English biologist F. Jowland Hopkins were published in 1912. The name “vitamine” was suggested for these substances by the biochemist Casimir Funk.
