Energy, Calories, and Nutrition (6.1.2)

Question 1

• The unit of measure for heat in chemistry is the calorie; the unit of measure for
heat in nutrition is Calories.

Answer 1

• The unit of measure for heat in chemistry is the calorie; the unit of measure for
heat in nutrition is Calories.

Question 2

• Protein and Carbohydrates each yield 4 kcal per gram; fats yield 9 kcal per gram.

Answer 2

• Protein and Carbohydrates each yield 4 kcal per gram; fats yield 9 kcal per gram.

Question 3

• Artificial sweeteners and fats give the impression of sweetness or fat without the
calories.

Answer 3

• Artificial sweeteners and fats give the impression of sweetness or fat without the
calories.

Question 4

A familiar measure for heat used by chemists is the
calorie.
Calories used to measure food energy, called
kilocalories or “large C calories”, represent 1000
chemists’ calories.
Nutritional labeling specifies the amount of each
nutrient per serving in a food product.
Protein contains about 4 kcal/gram, carbohydrates
contain about 4 kcal/gram and fats contain about
9 kcal/gram.
Caloric values can be calculated for each nutrient by
multiplying the number of grams of each nutrient by
its caloric value. A 26-gram serving of this cereal
contains 110 Calories.
Each serving provides 1 gram of protein (4 calories),
23 grams of carbohydrate (92 calories) and 1.5
grams of fat (14 calories).
Artificial sweeteners such as saccharin and
aspartame provide the sweetness of sugar with
practically no calories, since so little is used.
The artificial fat Olestra™, which is indigestible by
humans, has the taste and feel of fat with no
calories.
