Throughout this course, we have emphasized the importance of meeting nutritional needs through healthy food choices. This question asks you to apply your knowledge and demonstrate your understanding of our protein requirements. Show your reasoning for each part of the question.

a. John is a healthy, moderately active, 6 ft., 200 lb male, with a recommended caloric intake of 2000 calories a day. Based on the recommendation for protein intake, what is the range of calories from high-quality protein that he should consume on average?

Between ______________ calories and _______________ calories.

b. John goes to his favorite steakhouse and chooses a 12 oz. steak. The 6-ounce steak contains 96 grams of protein. How many calories of protein does that represent?

____________________ calories

c. Answer the following question:

Is the steak the only protein food that John needs to eat that day? Does it meet his requirement for protein, or should he take a supplement to meet his protein requirements? Check one of the following statements:

1. Yes, it meets his requirements, and he does not need the protein shake. ___________

2. No, it does not meet his requirement, and he needs the protein shake. ___________

Answer :

Final answer:

Based on the recommendation for protein intake, John should consume between 288 and 360 calories from high-quality protein on average. The 6-ounce steak containing 96 grams of protein represents 384 calories of protein. While the 12-ounce steak provides a significant amount of protein, it is advisable for John to include other protein-rich foods in his diet or consider a protein supplement to meet his protein requirements.

Explanation:

Protein Intake and Requirements

Protein is an essential macronutrient that plays a crucial role in various bodily functions. It is important to understand the recommended protein intake and how to calculate the caloric value of protein.

a. Range of Calories from High Quality Protein

Based on the recommendation for protein intake, John should consume an adequate amount of high-quality protein to meet his daily needs. The recommended daily protein intake for an average adult is around 0.8 grams per kilogram of body weight. To calculate the range of calories from high-quality protein, we need to determine John's weight in kilograms.

Given that John weighs 200 pounds, we need to convert it to kilograms. 1 pound is approximately 0.45 kilograms. Therefore, John's weight in kilograms is:

200 pounds * 0.45 kilograms/pound = 90 kilograms

Now, we can calculate the range of calories from high-quality protein. The caloric value of protein is approximately 4 calories per gram. Multiplying the protein intake in grams by 4 will give us the caloric value.

For John, the range of calories from high-quality protein would be:

0.8 grams/kg * 90 kilograms * 4 calories/gram = 288 calories to 360 calories

b. Calories of Protein in a 6-Ounce Steak

The 6-ounce steak contains 96 grams of protein. To calculate the calories of protein in the steak, we multiply the protein content by the caloric value of protein.

Calories of protein in the 6-ounce steak = 96 grams * 4 calories/gram = 384 calories

c. Meeting John's Protein Requirement

The 12-ounce steak that John chose contains a higher amount of protein than the 6-ounce steak. However, it is important to consider other protein sources in his diet to meet his protein requirement.

While the 12-ounce steak provides a significant amount of protein, it is not the only protein food that John needs to eat that day. It is recommended to have a balanced diet that includes a variety of protein sources such as lean meats, poultry, fish, eggs, dairy products, legumes, and soy products.

Based on the information provided, the 12-ounce steak alone may not meet John's protein requirement. It is advisable for John to include other protein-rich foods in his diet or consider a protein supplement to meet his protein requirements.
