Question

1. A meal of pasta contains 16 grams protein, 80 grams Carb and 8grams fat. a. How many Calories does the meal provide from these energy nutrients? (Remember Calories and kcals are the same thing) ________*___________= ________ kcal protein ________*___________ = ________kcal carb ________*___________ = ________kcal fat Total = _______ kcal b. What percentage of the Calories in the meal comes from each of the energy-yielding nutrients? (this relates to the second part of practice question

2) _____________________ = __________% kcal protein _____________________ = __________ % kcal carb _____________________ = __________% kcal fat Total = __________% (should be almost 100%) Doesn’t it make sense that it should add up to 100% since Protein, Carbohydrates and Fat are the three macronutrients that provide calories. *If the item has alcohol in it then that would have to be considered too.

2. If a Hot Dog has 150 calories per link and the fat content is 14 grams, how many calories are from fat and what percentage is that? Remember to keep straight what unit you are working with. You may need to change one unit to another (hint, hint). Show your work.

3. If ½ cup of ice cream is 120 calories and the calories from protein are 24, then how many grams of protein are in it?

4. If that ice cream provides you with 8% of the DV (daily value) of cholesterol then how many mg of cholesterol is in that serving. (The DV of cholesterol is 300 mg.) Remember what Daily Values are. They are the generic amounts used on food labels. So one serving of the ice cream is providing 8% of 300 mg so that is how many milligrams?

5. If MyPlan suggests that an individual has 2,200 kcal a day, then how many grams of carbohydrates, protein and fat are they ‘allowed?’ Use the amounts of 50% carbs, 20% protein and 30% fat.

Could use help/explanation on all 5 questions. Thank you

Answer 1

1) 16 gram protein, 80 gram carbs and 8 gram fats.

Each gram of protein has 4 calorie

Each gram of carb has 4 calories and

Each gram of fat has 9 calories.

So, 16 x 4 = 64 kcal

So, 80 x 4 = 320 kcal

So, 9 x 8 = 72 kcal

Total = 456 kcal.

B) 14.03% from protein

70.17 % from carb

15.78% from fats
