Changes

** The "vitamin deficiency" should go parenthetically under "Undernutrition" in the category column and the event type column could be something like "Discovery"

** " I'd like to see more coverage of malnutritions and severe nutrient deficiencies, specifically, when they were first identified, and when the nutrient for them was identified (e.g., scurvy being identified as due to vitamin C deficiency✔, rickets being identified as due to vitamin D deficiency✔, etc.)"

** Sebastian: cover more discoveries on vitamins.✔
