For centuries, general public have been aware that undeniable foods were necessary to good health, on the contrary it wasn't until the 1700s that the study of nutrients moved from folklore into science. James Lind, a surgeon with the British Regal Navy, realized scurvy was taking exceeding casualties from naval ranks than battles. Although it wasn't a common practice, Lind had heard of some trading ships that carried citrus fruits for health.
Lind took twelve sailors with scurvy and divided them into six groups. He fed them all the duplicate basic diet, but added a contradistinctive supplement for each group:
Cider
Oil of vitriol (sulfuric acid)
Barley water
Seawater
Vinegar
Oranges and lemons
By the time he ran absent of fruit, the citrus-fed sailors were cured. The only other aggregation that showed improvement (not as dramatic) was the cider drinkers. Although the abundant 'fruits' of his labour wouldn't earnings until more than a century later, his study opened the door to the eventual isolation of vitamin C and the development of supplements.
In the late 1800s, a Japanese physician observed that in Asia, where rice was the basic food for most people, those who apart ate polished bloodless rice were more susceptible to beriberi than those who ate whole-grain brown rice. His study showed that convert of diet could reverse the disease, and inspired extended studies that eventually identified the vital ingredient in rice hulls as thiamine, a B vitamin.
Vitamin A was first remoted in the early 20th century by the extraction of a lipid from fish oil used to treat rickets -- a public disease at the time. Ironically, it was eventually erect that it was the vitamin D in the lipid -- not the vitamin A -- that was culpable for elimination of rickets.
In 1912, a Polish scientist dubbed the basic nutrients in foods 'vitamines', from the Latin vita-, belief life, and -amine, from the chemical compounds get going in the nutrient loney from rice husks. It was eventually discovered that not all vitamins were amines, so the name was shortened to 'vitamin'.
