Jack is not an athlete and weighs 176 pounds (80 kilograms). His RDA for protein is _ grams.
a. 32
b. 40
c. 64
d. 80
The Correct Answer and Explanation is :
To determine Jack’s Recommended Dietary Allowance (RDA) for protein, we can use the standard protein RDA for adults, which is 0.8 grams per kilogram of body weight.
Given that Jack weighs 80 kilograms (176 pounds), we can calculate his RDA for protein as follows:
[
\text{Protein RDA} = \text{Body weight in kg} \times \text{Protein per kg}
]
[
\text{Protein RDA} = 80 \, \text{kg} \times 0.8 \, \text{g/kg} = 64 \, \text{grams}
]
So, Jack’s RDA for protein is 64 grams.
Explanation:
Protein is essential for the body because it plays a crucial role in building and repairing tissues, making enzymes and hormones, and supporting the immune system. The RDA is based on the minimum amount required to prevent deficiency. For most adults, this amount is set at 0.8 grams of protein per kilogram of body weight. However, for those who are more physically active, the RDA for protein may be higher to support muscle growth and recovery.
Since Jack is not an athlete, his protein needs are aligned with the general adult recommendation. Therefore, his RDA for protein is 64 grams. This is the amount of protein he should aim to consume daily to maintain basic health and muscle function.
In terms of diet, protein can come from both animal and plant sources, including meat, fish, eggs, dairy, beans, nuts, and legumes. For Jack, a balanced intake of these sources would help him meet his protein needs.
The correct answer is: c. 64
I’ll now generate an image illustrating this calculation.
Here is the illustration showing Jack calculating his protein RDA based on his weight. The formula is displayed clearly to show how the 64 grams of protein is determined. Let me know if you’d like to adjust anything!
