The idea of food as a powerful tool for healing and prevention is not new, tracing its origins over 2,500 years to ancient civilizations. The pivotal concept, encapsulated by Hippocrates's famous quote, laid the philosophical foundation for what we now understand as the sophisticated 'food is medicine' approach to health.

Historically, scurvy was a devastating disease, killing more British sailors during the 18th century than enemy action. What was the old cure for scurvy was a question that perplexed doctors for centuries, with the effective solution of fresh food, particularly citrus fruit, repeatedly being discovered and then forgotten.

In 1929, Danish biochemist Henrik Dam observed that chickens fed a fat-free diet developed severe, spontaneous hemorrhages. This discovery ultimately led to the isolation of vitamin K from alfalfa, and marked a pivotal moment in nutritional science.

In 1929, Danish biochemist Carl Peter Henrik Dam, while studying cholesterol in chickens, observed a hemorrhagic disease that led to the discovery of a new nutrient he named 'Koagulations vitamin' or vitamin K. While Dam's initial work centered on this blood-clotting factor, the subsequent discovery of its distinct forms, particularly vitamin K2, reveals a much deeper and more complex nutritional story.

In the early 20th century, pernicious anemia was a fatal and mysterious disease. It was during the search for its cure that Dr. William B. Castle famously referred to vitamin B12 as the "extrinsic factor," differentiating it from a necessary substance produced within the body. This name highlights its crucial role as a nutrient that must be obtained from external dietary sources.

In the late 19th century, beriberi was a widespread and deadly scourge, particularly in Southeast Asia, and its cause was a medical mystery. This prevailing confusion shaped the early investigation into what was the original hypothesis of beriberi, leading researchers to incorrectly suspect an infectious agent rather than a dietary deficiency.

During epidemics in the early 20th century, especially in the American South, the mortality rate of pellagra was high, with approximately 100,000 deaths recorded between 1906 and 1940. This niacin deficiency disease proved fatal for many, largely impacting vulnerable populations.

Coined in 1989 by Dr. Stephen DeFelice, the term **nutraceuticals** represents a modern bridge between nutrition and pharmaceuticals. While the name is relatively new, the underlying concept of using food for medicinal benefit dates back thousands of years.

Hippocrates, often called the 'Father of Medicine,' was the first to propose that diseases were caused by natural, not supernatural, factors. This foundational belief underpinned the Hippocrates regimen, a holistic approach to wellness centered on restoring balance to the body and fostering its innate healing abilities.

Over 80% of children in industrialized cities like Boston suffered from rickets around 1900, a condition that drove the critical research leading to the discovery of vitamin D3. This exploration reveals the specific timeline and the brilliant minds who pinpointed the precise chemical structure of this vital nutrient.
