Summary A nutrition minicourse for 11th and 12th grade students has been developed at M.l.T. It can be incorporated into existing high school biology or chemistry courses as a 4- to 5-week special unit, deals with principles of food composition, health, and nutrient labeling. Four different types of American meals are studied (“Drive-in” hamburger, Macrobiotic, Basic Four Food Groups, and Vegetarian). The meals are fed to weanling laboratory rats, and water, carbohydrate, fat, and protein contents of the meals are determined chemically by standard analytical methods adapted for high school use. Student observations of differing biological effects and chemical compositions serve as starting points for the study of food components listed on food labels and in food composition tables. Recommended Dietary Allowances are studied as dietary goals and as nutrient labeling standards. Two developmental trials of the teaching materials and a teacher workshop indicate feasibility for high school classroom use. |
