Recommended Dietary Allowance Lab: Comparing Your RDA for Energy and Nutrients to Your Actual Nutritional Intake Key Question: Does my diet meet the Recommended Dietary Allowance (RDA) for energy and nutrients considered adequate to meet my needs (maintain weight) under environmental stress? Hypothesis: If I track the food I consume for 5 days, I will find that my diet does not meet my RDA for energy and nutrients considered adequate to maintain my needs under environmental stress. I'm a busy teenager, my meals are often on the go. Since my daily activities, such as volunteering, prevent me from getting home in time for dinner, I often have to rely on fast food for my meal. Furthermore, morning classes rarely allow me to have a proper breakfast, which results in me buying breakfast in the school canteen. Also, when I go out with my friends, we don't choose the healthiest foods. All of these factors tell me that my diet is inadequate to meet my needs under environmental stress. Variables: Independent variable: the food consumed Dependent variable: the nutritional value of the food consumed compared to the RDA Controlled variables: same reference for the nutritional values of the foods used for consistency of information Materials:* Internet* Nutrition booklet with calculator ------- -----Procedure:1. Determine your total daily calories (kcal/day) based on your nutritional profile on the following website: http:www.cyberdiet.com/profile/profile.html2. Convert this total to total kJ of energy per day (using the ratio 1 kcal = 4.2 kJ)3.a. Use a calculator for this and the following calculations4. Calculate total energy in kJ of protein per day based on the fact that a person needs about 10% protein in an ideal balance
