This document discusses vitamins, nutrition, and body mass index (BMI). It defines vitamins as organic compounds needed in small amounts for normal metabolism. Vitamins are categorized as either fat-soluble (A, D, E, K) or water-soluble. Fat-soluble vitamins are stored in fatty tissues while water-soluble vitamins dissolve in water and must be replenished daily. Important minerals like calcium, iron, magnesium and others are also outlined. Proper nutrition and obtaining necessary vitamins and minerals from foods is vital for health. BMI is defined as a ratio of weight to height used to indicate healthy body weight.
