** THE SCIENCE OF NUTRITION ** We make our food choices based on taste, convenience, emotions, religion and culture, health beliefs, nutrition, medical conditions, and socioeconomic status. Nutrition is a relatively new science. Because we all eat, we are all experts, but our understanding of the science is lacking. The first known reference to nutrition was by Hippocrates about 2500 years ago, when he said: **“Let food be thy medicine and let medicine be thy food.”** The discovery of essential nutrients highlighted nutritional science from this point to the 20th century. Everything in this world and beyond is made up of chemicals. The building blocks of chemicals are ** //elements// **. These elements are the symbols that appear on the periodic table. Look at the periodic table to determine the elements that make up common foods. There are ** six main nutrients ** needed in your body for it to function properly. The main nutrients include:


 * 1) Carbohydrates
 * 2) Protein
 * 3) Fat
 * 4) Vitamins
 * 5) Minerals
 * 6) Water

Although many of these 6 ** nutrients ** contain the same ** elements **, they are arranged differently. Use various resources (textbooks; reference books- both in nutrition and science; pamphlets; internet; etc.) to determine the common ** elements ** (from the periodic table) found in each of the main ** nutrients **. Present your information in this graphic organizer:
 * Elements ** are presents in varying amounts in the foods we eat. Each contains specific elements.
 * HOMEWORK: **
