The energy obtained from carbohydrates, proteins, and fats is measured in units called calories.
Carbohydrates 1g = 4 calories
Protein 1g = 4 calories
Fat 1g = 9 calories
Alcohol 1g = 7 calories
A slice of bread has 9g of carbohydrates, 2g of protein, and 1g of fat.
Get out a piece of paper and see if you can do the calculations…
9 grams carbohydrates x 4 calories/gram
= 36 calories + 2 grams protein x 4 calories/gram = 8 calories + 1 gram fat x 9 calories/gram
= 9 calories _
Total calories = 53
