You are going for a trip on the web to plan out your meals for the day! You need to keep track of the energy nutrients. Be very careful to write down how many servings you are going to eat. After you plan your Breakfast, Lunch and Dinner, analyze your daily intake and compare it to the FDA recommendations.

Questions for the Activity:

1. Analyze your Breakfast, Lunch and Dinner separately. Which meals are within the recommendations? Which meal is heavier in fat, carbohydrate, and protein? Do you think that the total for the day will be withing the FDA recommendations?
2. After you plan you three meals, draw the pie chart for your food intake for the three meals and the FDA recommended daily intake. Are you within the recommendations? Draw the graphs here and write the percentage from each nutrient in each region.

Breakfast	Lunch	Dinner

Daily Total	FDA

3. If you are not within the recommendations, try changing three foods during the day to see if you can get in line with the recommendation. Write the changes you make. After you try to change your meals once, go to the next problem and use the TI-73 program NUTRITIO.
4. Enter and run the TI-73 program NUTRITIO, given below, to quickly do the your work. Remember that all of the steps you just did to calculate your circle graphs is being done in much the same way when you use this program. See the TI-73 Guidebook for details on entering and running a program.

You will be asked to input the grams for each nutrient. Here is what you will see!
