1. Food Label Activity Ms. Levasseur Biology

2. Purpose: To examine the typical teenage diet and compare the organic compounds ingested to those required for healthy living. Problem: Will the foods I consume align with the recommendations set forth by the Food & Drug Administration’s guidelines for intake of proteins, carbohydrates, and fats?

3. Background Information: According to the FDA, it is helpful to know that a 2,000- calorie diet is about right for moderately active women, teenage girls, and sedentary men, and 2,500 calories is the target level for many men, teenage boys, and active women. Some active men and teenage boys and very active women may want to base their calorie consumption of 2,800 calories per day. While it is important to note that you are consuming the correct amount of calories, it is also important to have the right amount of the organic compounds that make up this diet. Almost everything we eat is a protein, lipid, or carbohydrate... many are combinations of these organic compounds. Most of the calories you consume for the day should come from carbohydrates (55 - 60%), proteins (15-20%), and lipids (25 - 30%).

7. Total Carbohydrate Calories / Grand Total Calories X 100 = % carbohydrates b. Total Protein Calories / Grand Total Calories X 100 = % protein c. Total Lipids Calories / Grand Total Calories X 100 = % lipids Table #4: Percent of Daily Calories from Carbohydrates, Proteins, and Lipids % carbohydrate calories % protein calories % lipid calories

8. Analysis Questions: 1.How close were you to the recommended percentages of carbohydrates (55-60%), protein (15-20%), and lipids (25- 30%)? 2.If your numbers are higher than the ideal diet in one of your organic compounds, then which food item(s) will you consider decreasing or eliminating from your diet to improve it? Be specific. 3.If your diet is too low in one or more organic compound, which food item(s) will you consider increasing to improve your diet? Be specific.

9. Conclusion: As always… Write the answers in a flowing paragraph to the following questions: 1.What did you like about this activity? 2.What did you learn about this activity? 3.What would you change to make this activity better? 4.What possible sources of error did you have?
