[History of vitamins]

Area of Science:

• Biochemistry and Nutritional Science
• History of Medicine and Nutrition

Context:

• Beriberi initially misunderstood as microbial, later linked to nutritional deficiencies.
• Early 20th-century research shifted focus from toxins to essential dietary components.

Purpose:

• To trace the historical development of vitamin discovery.
• To elucidate the scientific journey from nutritional observation to molecular identification of vitamins.

Summary:

• Initial observations linked beriberi to poor nutrition, prompting research into 'accessory factors'.
• Feeding experiments revealed substances essential for metabolism, not synthesized by the body.
• Between 1912 and 1948, these factors were isolated, identified, and collectively named vitamins.

Impact:

• Established the field of vitamin research and nutritional science.
• Led to the identification of essential micronutrients crucial for human health.
• Revolutionized understanding of diet-related diseases and metabolic functions.
