B. The Food Guide Pyramid

The Food Guide Pyramid was released by the USDA in 1992 [ 7 ], and has been widely distributed to both health professionals and consumers. Its solicitation is double : It is a simpleton and actionable graphic, and it is based on detailed analyses that demonstrate its scientific accuracy. Both the shape and the contentedness of the Food Guide Pyramid undergo across-the-board test. numerous stress groups were conducted to ensure that consumers understood the messages being conveyed, and that the pyramid was a meaningful graphic for offering dietary guidance [ 45 ]. In addition, extensive analyses were conducted to determine what guidance would ensure adequacy ( provision of commend levels of nutrients ) and temperance ( low-fat, low-energy choices from each of the groups ) [ 45 ]. finally, distinctive dietary patterns in the United States were considered, which led to the choice of the food groups, and the number of servings of each, that would provide the recommend levels of nutrients at three daily energy levels ( 1600, 2200, and 2800 kcal/day ) as shown in Fig. 2. Because the food groups are broadly defined, they can be adapted to meet particular cultural and personal preferences. thus, the Food Guide Pyramid combines the dietary guidelines and the RDAs/DRIs into a single tool that is both scientifically based and consumer friendly. Serving sizes for the foods in each Food Guide Pyramid food group, except the tap, are specified [ 7 ] as shown in Fig. 3. Serving sizes are smaller than many distinctive portions. For exemplar, a slice of bread or one-half cup of pasta is a serve of the grains group, although distinctive portions are substantially larger than these. ( Adults typically consume about two slices of bread per eating affair, and about one cup of pasta [ 46 ]. ) FIGURE 3. What counts as a serve ?

[ From U.S. Department of Agriculture and U.S. Department of Health and Human Services ( 2000 ). ‘ ‘Dietary Guidelines for Americans, ” 5th ed., Home and Garden Bulletin No. 232. U.S. Government Printing Office, Washington, DC. ] Copyright © 2000 many variations of the Food Guide Pyramid have been proposed, but most are specific interpretations of the pyramid ‘s more general steering. For case, a children ‘s pyramid was released by the USDA in 1999 that offers a graphic that includes foods frequently consumed by children [ 47 ] ( see Fig. 4 ). It is besides a departure from the master ( pornographic ) Food Guide Pyramid, in that the importance of physical action is emphasized with pictures of children engaged in respective types of physical activeness shown around the pyramid graphic. Although pyramids for assorted cultural or cultural groups have been proposed, there is rarely the like charge of analytic research for these variations as was conducted for the original, more general, Food Guide Pyramid. Health professionals should be timid about recommending food guides that have not undergone the rigorous examination of the Food Guide Pyramid.

[ From U.S. Department of Agriculture ( 1999 ). ‘ ‘Tips for Using the Food Guide Pyramid for Young Children 2 to 6 Years Old, ” Program Aid 1647. U.S. Department of Agriculture, Center for Nutrition Policy and Promotion, Washington, DC. ] Copyright © 1999 The Food Guide Pyramid is based on the 1989 RDAs and on the 1990 dietary guidelines. As explained in Section II of this chapter, the 1989 RDAs are being substantially revised as function of the process of setting the fresh DRIs. In addition, the dietary guidelines have been modified and expanded twice ( in 1995 and 2000 ) since the pyramid was developed. To date, the entirely deepen in either type of guidance that is likely to importantly affect the Food Guide Pyramid is the increase recommendation for calcium. As reflected in the Food Guide Pyramid that is included in the 2000 dietary guidelines [ 5 ], three ( quite than two ) servings of dairy products would be required for adults over the age of 50 in orderliness to meet the modern AI for calcium of 1200 mg/day. Three servings would besides be recommended for children and youthful adults 9–18 years of long time ( preferably than those 13–24 years of age ). It is anticipated that the Food Guide Pyramid will be reevaluated when the process of setting the DRIs is complete .
