- 9 cal
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept.
We are asked how many calories alcohol supplies compared to the other major nutrients.
Step 2: Key Approach.
A quick way to remember energy values is to rank them: carbohydrate and protein each give 4 kcal, fat gives 9 kcal, and alcohol falls in between at 7 kcal.
Step 3: Detailed Explanation.
This is why alcohol is labelled an empty calorie food, it hands the body real energy, close to fat's level, but brings almost no protein, vitamins, or minerals with it. Checking the choices, 1 cal is far too small to be a nutrient's energy value, 4 cal belongs to carbohydrate or protein, and 9 cal belongs to fat, so neither fits alcohol.
Step 4: Final Answer.
The correct energy value for alcohol is 7 cal, between the value for carbohydrate or protein and the value for fat.
