Question

the table shows the amount of protein, carbohydrate, and fat for several different foods.
food\tprotein (g)\tcarbohydrate (g)\tfat (g)
apple, 1 medium\t0\t22\t0
bacon, 2 slices\t5\t0\t6
chocolate, 1 bar\t3\t23\t13
eggs, 2 whole\t12\t0\t9
2% milk, 1 cup\t8\t12\t5
potato chips, 15 chips\t2\t14\t10
sourdough bread, 2 slices\t8\t36\t1
skinless roasted turkey, 3 slices\t11\t3\t1

1. interpret data per serving, which of the foods included in the table has the most protein? which has the most carbohydrates? which has the most fat? eggs got more protein, sour bread got the most carbs, chocolate got the most fat
2. reason quantitatively approximately how many more calories are there in 2 slices of bacon than there are in 3 slices of roasted turkey? why is there a difference?

Explanation:

Step1: Recall calorie - conversion

Protein and carbohydrates have 4 calories per gram, fat has 9 calories per gram.

Step2: Calculate bacon calories

Bacon: $(5\times4)+(6\times9)=20 + 54=74$ calories.

Step3: Calculate turkey calories

Turkey: $(11\times4)+(1\times9)+(3\times4)=44+9 + 12=65$ calories.

Step4: Find calorie difference

$74 - 65 = 9$ calories. The difference is due to different amounts of macronutrients.

Answer:

There are about 9 more calories in 2 slices of bacon. The difference is due to macronutrient amounts.
