Document Summary
6 classes of nutrients : carbohydrates, lipids (fats), proteins(macros), water, vitamins, Body composition: 60% water, 13-21% fat (males)/23-31% females, carbs, protein, vitamin minerals and other constituents make up remainder. >minerals and water are inorganic: do not contain carbon. Essential nutrients- body makes insufficient quantities to meet needs, therefore need to obtain these nutrients through food. > therefore fat has a greater energy density than carbs and protein. Energy is created when bonds between nutrients atoms break, releasing energy. Metabolism: process by which nutrients are broken down to yield energy or used to make body structures. Vitamins: 13 vitamins, organic, do not provide energy, but facilitate the release of energy from carbohydrate, fat and protein, and participate in numerous other activities throughout the body. >water soluble : c and 8 b vitamins. Minerals: 16 minerals are essential in human nutrition, do not yield energy. Water: metabolic reaction purposes, supplies medium for transportation of vital materials.
