With a normal diet, only about 10 percent of our total calories come from protein.
a.All three statements are true.
b.Two of the three statements are true.
c.Only one of the statements is true.
d.None of the statements is true.
The correct answer and explanation is :
The correct answer depends on verifying whether the statement is true or false.
Answer: C. Only one of the statements is true.
Explanation:
Protein is one of the three macronutrients in our diet, alongside carbohydrates and fats. The statement in the question claims that only about 10% of total calories in a normal diet come from protein. However, this figure is not entirely accurate when considering general dietary recommendations.
- Recommended Protein Intake:
- According to the Dietary Guidelines for Americans, protein should make up between 10-35% of daily caloric intake.
- The Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight for an average adult.
- In most standard diets, protein typically accounts for 15-20% of total daily calories, not just 10%.
- Typical Protein Consumption:
- In Western diets, the percentage of calories from protein often exceeds 10%, especially with diets high in meat, fish, dairy, and legumes.
- The protein intake in different populations may vary, but in general, most people consume more than 10% of their calories from protein unless they follow specific low-protein diets.
Why is Option C Correct?
Since the statement “only about 10 percent of our total calories come from protein” is not universally true, only one of the three possible statements in the question set would be correct. Hence, option C (Only one of the statements is true) is the correct choice.
