Carencia de vitaminas

The video discusses the significant impact of vitamins on health, highlighting how deficiencies can lead to diseases like scurvy and rickets. It focuses on Dr. Joseph Goldberger's groundbreaking research in the early 20th century, which linked pellagra, a widespread disease in the southern United States, to a lack of dietary variety rather than germs. Goldberger's work led to the discovery of Vitamin B3 (Niacin) as the key to preventing pellagra, demonstrating the direct connection between vitamins and health. This discovery has virtually eradicated pellagra in the U.S. through dietary changes.
