Question

Activity 1 -Energy Where you get energy and why you need it You get energy from only three of the classes of nutrients: proteins, fats, and carbohydrates. (Alcohol, which is not a required nutrient, also provides energy.) Energy from food is measured in Calories. 1. Use your memory, your notes, and a calculator to fill in the following table Cal/ounce Cal/g x 28.4 nutrient protein carbohydrate fat alcohol Cal/lb Cal/gx454.5 Cal/g Cal/oz Cal/lb 13 1313 2.Here is the Nutrition Facts label from your instructor's breakfast cereal. As you can see, part of the label is missing. Based on this label, how many calories are there in one serving of this cereal? (Note: You need to know that Total Carbohydrate on the food label includes fiber, which has no Calories.) Nutrition F Serving Size: 1 cup (55 Servings per containen Total Fat 2.5 Seturated Fet O.58 Trans Fot or Cholesterol om Sodium 270 mg Total Carbohydrate 38 iber Protein 9 g

Explanation / Answer

here the amount of carbohydrate = 38 gm but net carbohydrate that will provide energy = 38-11= 27gm

the amount of fat = 2.5 gm

the amount of protein = 9 gm

so total calories from this serving = 27x4 + 2.5x9 + 9x4 = 166.5 cal
