Skill Level 2

1. Have the Nutrition Honor.

The answers for the Nutrition honor can be found in the Household Arts chapter of this book.

2. Keep a record of what and how much food you eat for two weeks. Compare your diet to that of the food pyramid.

If you have access to the Internet, you can visit the USDA's MyPyramidTracker.gov web site, the official home of the Food Pyramid. Once you register, you can enter all the foods you eat in a day, and it will analyze your nutrient intake (among other things) based on this information. MyPyramidTracker can retain the information you enter for up to a year, so tracking it for a week will be easy.

If your Pathfinders do not have access to the Internet, have them record their diets on paper. You can then use the website to extract the necessary data by entering each food individually, or you can find a cookbook that has nutrient values of various foods in an appendix. Another option would be to meet in a place that has public Internet access, such as a library or Internet cafe. Then your Pathfinders can enter the data they have collected for a week and analyze it there.

The values in the table below are for children who are physically active for 60 minutes or more per day. Use the USDA website for adults and less active children.
