(Fotokat/Age Fotostock America, Inc.) C H A P T E R 2 C O N C E P T S There are many types of nutrition recommendations designed to promote health by guiding nutrient intake and food choices. The Dietary Reference Intakes are a set of reference values for the amounts of calories, nutrients, and food components needed in the diets of healthy people. The Food Guide Pyramid is a tool to plan diets that meet nutrition recommendations. Food labels provide information about the nutrient content of individual foods and how they fit into a healthy overall diet.

The New York Times U.S. Considers Food Labels with Whole-Package Data By Sherri Day Nov. 21, 2003—The Food and Drug Administration said yesterday that it was considering whether to require food companies to list nutrition information in its entirety, rather than by serving size, on packaged-food labels. Currently, if a package contains more than one serving, consumers must multiply nutrition data by the number of servings to determine total calories, fat and carbohydrates. Some consumer groups and nutritionists have argued that such food labels are misleading and could cause consumers to take in more calories, sodium and fat than they realize. Now, it seems, the F.D.A. may agree.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
