Endemic goiter was so prevalent in the early 20th century in certain regions, like the American Midwest's 'goiter belt', that it became a major public health concern. This widespread issue was the primary catalyst for the practice of adding iodine to salt, a simple yet groundbreaking solution to a devastating deficiency.

In 1912, Polish American biochemist Casimir Funk coined the term "vitamine" after his groundbreaking work on deficiency diseases like beriberi. This moment sparked a global awareness of essential nutrients, with a coalition of researchers, public health officials, and marketers working to popularize vitamins and transform modern nutrition.

The first iodized salt appeared on grocery store shelves in Michigan on May 1, 1924, marking a pivotal moment in public health history. This initiative was a response to widespread iodine deficiency, particularly in the "goiter belt" region of the Great Lakes and Northwest. The story of how they began adding iodine to salt is a tale of scientific discovery, public health advocacy, and a simple solution to a devastating problem.

In 1931, a researcher named Lucy Wills first discovered that a factor in brewer's yeast could prevent a serious form of anemia in pregnant women. This nutrient, later identified and synthesized as folic acid, was originally used for combating macrocytic anemia and has a rich history that paved the way for modern nutritional science.

For centuries, fish liver oil was a folk remedy, especially for conditions like rickets, but its true biological power was unknown. So, what vitamin was isolated from fish liver oil in 1917? The scientific breakthrough of isolating this specific nutrient represented a monumental step forward in understanding human health and diet.

In 1747, a British naval surgeon named James Lind proved that citrus fruits could cure scurvy through a controlled experiment, a disease that had killed millions of sailors. However, pinpointing who truly discovered the value of vitamin C involves contributions from multiple scientists over centuries.

The medicinal use of iron can be traced back to antiquity, with ancient civilizations employing iron-rich substances to combat weakness. However, the first recognized oral iron supplement, known as Blaud's pills, was not introduced until 1832.

The origins of the word "scurvy" are tied to early linguistic descriptions of its symptoms, primarily the scaly skin and general miserable condition of those afflicted. This is why is it called scurvy, a name that evolved from older Germanic and Norse words to describe the affliction's visible effects.

Thiamine was the first water-soluble vitamin to be discovered and its history is deeply intertwined with the ancient disease beriberi, which long plagued populations relying on a polished rice diet. The journey to understand this essential nutrient reveals a fascinating narrative of colonial medicine, groundbreaking animal experiments, and international scientific collaboration.

In 1912, Polish biochemist Casimir Funk coined the term 'vitamine' after recognizing that certain diseases, like beriberi and scurvy, were caused by specific nutrient deficiencies rather than infections. His groundbreaking theory, detailed in his 1912 publication, revolutionized nutritional science, even though he did not successfully isolate a specific vitamin that year.
