Examine the macronutrient profile of the three types of milk. What was the source of the extra calories?multiple choice 2FatProteinSugar

To examine the macronutrient profile of various types of milk (such as whole, skim, and 2% milk), it's essential to analyze the contributions of fat, protein, and sugar to the overall caloric content.

1. Whole Milk: This typically contains about 3.25% fat, along with protein and sugar (lactose). The fat in whole milk provides a significant source of calories.

2. 2% Milk: Contains 2% fat, which results in fewer calories than whole milk but still contributes a notable amount to the total caloric content.

3. Skim Milk: Has virtually no fat (less than 0.5%), hence, the calories primarily come from protein and sugar.

Analysis of caloric sources:

• Fat: Each gram of fat provides approximately 9 calories. Therefore, whole and 2% milk can have a higher caloric content based on fat.
• Protein: Each gram of protein provides approximately 4 calories. All types of milk contribute protein, but it is a smaller source of overall calories compared to fat.
• Sugar (Lactose): Each gram of sugar also provides around 4 calories. Sugar contributes to the total calorie count but is generally less impactful than fat in whole and 2% milk.

Conclusion:

Therefore, the source of extra calories in whole and 2% milk primarily comes from Fat.

Final Answer:

Fat is the source of the extra calories in milk types with higher fat content.
