Estimate and measure your caloric needs and outputs. 3. Compare the nutritional value of various foods. Before Lab : 1. Read Chapter 21.13 - 21.20 in Campbell et al. , Biology: Concepts and Connections . 2 nd , 3 rd or 4 th ed. or 21.14 -21.24 in the 5 th ed. or 21.14 – 21.23 in 6 th ed. 2. This lab requires the use of a pedometer. Completion of at least 5 lab units, with write-ups submitted and quizzes taken, is required before the equipment will be sent to you. In addition, you must submit the completed request for equipment on the last page of this lab unit. In addition, please send an e-mail request for the equipment to patty_aune@ncsu.edu or james_mickle@ncsu.edu. Turn in: This entire completed lab unit, including all tables and questions. Introduction All organisms require a source of energy and raw materials for growth, maintenance, and reproduction. Nutrition is the study of the needs, use and acquisition of the complex of organic and inorganic substances referred to as food . Some organisms, such as plants, require only inorganic substances from their environment and have the ability to fashion these inorganic substances directly into organic substances. Other organisms, such as animals, must have an outside source of organic foodstuffs. Nutrition Animals, unlike photosynthetic plants, must have an external source of organic compounds as a part of their food. Included in these organics must be those amino acids and vitamins that they cannot manufacture in their bodies and therefore must be in the diet. Like plants, animals must have external sources of minerals. Activity A Nutritional Analysis For this activity, you will maintain a record of all the food that you eat for a five day period. In lab, you will analyze the diet you have recorded using a computer software package that gives nutritional information about the food that you have eaten. You can then evaluate your diet for nutritional excesses and deficiencies. This information will allow you to make modifications in your diet as necessary. Activity A-1 Estimate Your Energy Needs Your energy needs have two components: the basal metabolic rate (BMR) and energy for activities. The BMR is defined as energy needs at rest. BMR varies with height, weight, gender, and age. Energy for activities includes the energy needed for skeletal muscle action. This varies with the level of activity which is correlated to a certain extent with occupation. In order to estimate you total energy needs, we must estimate each of these two components.
