Nutrition calculation

 

Carbohydrates: 4g per serving
Fats: 10g per serving
Proteins: 5g per serving

Calories from Carbohydrates: $\text{Carbohydrates} = 4g \times 4 \text{kcal/g} = 16 \text{kcal}$

Calories from Fats: $\text{Fats} = 10g \times 9 \text{kcal/g} = 90 \text{kcal}$

Calories from Proteins: $\text{Proteins} = 5g \times 4 \text{kcal/g} = 20 \text{kcal}$

Step 1: Calculate the kcal contributed by the carbohydrates, fats, and proteins per serving

From the label:

• Carbohydrates: 4g per serving
• Fats: 10g per serving
• Proteins: 5g per serving

Calories from Carbohydrates: $\text{Carbohydrates} = 4g \times 4 \text{kcal/g} = 16 \text{kcal}$

Calories from Fats: $\text{Fats} = 10g \times 9 \text{kcal/g} = 90 \text{kcal}$

Calories from Proteins: $\text{Proteins} = 5g \times 4 \text{kcal/g} = 20 \text{kcal}$

Step 2: Calculate the TOTAL kcal/serving

$\text{Total kcal/serving} = 16 \text{kcal} + 90 \text{kcal} + 20 \text{kcal} = 126 \text{kcal}$

Step 3: Calculate the TOTAL kcal in the package

• Number of servings per container: 2

$\text{Total kcal in the package} = 126 \text{kcal/serving} \times 2 \text{servings} = 252 \text{kcal}$

Step 4: Does the total kcal/serving that you calculated match the total on the package? Why or why not?

• The total kcal per serving on the package is listed as 124 kcal.
• My calculation shows 126 kcal per serving.

Reason for discrepancy: This small difference could be due to rounding in the values of macronutrients (carbs, fats, proteins) or the energy value of each macronutrient. The FDA allows for some rounding in nutritional labels, which can cause such slight discrepancies.

Step 5: Energy density evaluation

• Calories per serving: 124 kcal
• Serving size: 8 fl oz (240 mL)

Considering the serving size and calorie content, this food (likely a dairy-based drink due to the high fat content and presence of proteins) has a moderate calorie density. It is not particularly high in calories compared to many processed foods or snacks, which can have much higher calorie densities. This product provides a balance of macronutrients (fat, protein, carbohydrates) that contribute to its overall energy content, making it neither highly energy-dense nor low in energy density, but rather moderate.

This balanced energy content could make it suitable for a snack or part of a meal rather than being classified as a high energy-dense food that provides a lot of calories with little volume
