This article talks about the discovery of scientists and diseases that are caused by vitamin deficiency. Initially, we will learn about how chicken blindness was treated in ancient Egypt, which in our time is caused by vitamin A deficiency. Next we learn that in 1747 James Lind discovered that citrus products help prevent scurvy, and in 1753 Lind published his text " Treatise on the Scurvy». We also learn that Lind was not widely recognized among the participants of the Arctic expeditions of the Royal Navy in the 19th century, it was believed that scurvy could be prevented by observing hygiene rules and much more. At the beginning of the 20th century, Robert Falcon Scott discovered the theory that scurvy is caused by "tainted" canned food. In 1881, Nikolai Lunin studied the effects of scurvy at the University of Tartu. He conducted the experiment on mice, From there followed a conclusion that was rejected by other researchers. In 1897, Christian Eikman discovered which product prevents vitamin deficiency disease and the following year Friedrich Hopkins postulated. Hopkins was awarded the Nobel Prize in Physiology or Medicine in 1929 together with Christian Eikman for the discovery of several vitamins. Fletcher and Funk named the micronutrient complex "vitamin". In 1931 Albert St. Gyorgy and Joseph Svireli determined that "hyaluronic acid" is vitamin C, for which in 1937 St. Gyorgy was awarded the Nobel Prize, and in 1943 Edward Albert Doisi and Henrik Dam were awarded the Nobel Prize for the discovery of vitamin K.
