MULTIPLE CHOICE
1. The primary function of carbohydrates in the body is to provide
|
a. |
sweetness. |
|
b. |
satiety. |
|
c. |
energy. |
|
d. |
dietary fiber. |
ANS: C
The most important function of carbohydrates in the body is to provide energy. Unrefined sources of carbohydrates do provide dietary fiber, but refined carbohydrates do not. Similarly, unrefined carbohydrates may add to satiety, but refined carbohydrates contribute less to satiety than do protein and fat. Simple carbohydrates provide sweetness; this is pleasant but not essential to the body.

2. Fructose, galactose, and glucose are examples of
|
a. |
disaccharides. |
|
b. |
polysaccharides. |
|
c. |
monosaccharides. |
|
d. |
complex carbohydrates. |
ANS: C
Fructose, galactose, and glucose each consist of a single carbohydrate unit and are therefore monosaccharides. Disaccharides consist of two carbohydrate units; polysaccharides and complex carbohydrates consist of several carbohydrate units.

3. The sweetness in a banana comes mostly from
|
a. |
fructose and sucrose. |
|
b. |
fructose and glucose. |
|
c. |
glucose and maltose. |
|
d. |
maltose and sucrose. |
ANS: A
The most common sugars found naturally in fruits such as bananas are fructose and sucrose. It may also contain some glucose, but this contributes less to the sweetness. Fructose is the sweetest of the sugars, and so it contributes most to the sweetness. Maltose is found only in germinating grains or as a product of partial starch digestion in the gut.

4. A blood glucose level of 60 mg/dL is considered
|
a. |
inconclusive. |
|
b. |
representative of hypoglycemia. |
|
c. |
representative of normoglycemia. |
|
d. |
representative of hyperglycemia. |
ANS: B
The normal range for blood glucose level is 70 to 100 mg/dL. Therefore, 60 mg/dL is considered to represent hypoglycemia.

5. In comparison with table sugar (sucrose), honey tastes _____ because it contains _____.
|
a. |
sweeter; fructose |
|
b. |
sweeter; maltose |
|
c. |
less sweet; fructose |
|
d. |
less sweet; maltose |
ANS: A
Honey is sweeter than table sugar because it contains fructose, the sweetest of all the sugars. Maltose is less sweet than table sugar and is not found in honey; it is found only in germinating grains and as a product of partial starch digestion.

6. Someone who follows a strict vegetarian (vegan) diet and eats very few refined foods is likely to have _____ intake of _____ carbohydrates and dietary fiber.
|
a. |
low; complex |
|
b. |
high; complex |
|
c. |
low; simple |
|
d. |
high; simple |
ANS: B
Strict vegetarian diets contain only plant foods that have high levels of carbohydrates. Refined foods contain more simple sugars and some starch. Unrefined foods contain mostly complex carbohydrates and fiber. Therefore, someone who follows a strict vegetarian diet and eats very few refined foods is likely to have a high intake of complex carbohydrates and dietary fiber.

7. A person would be most likely to produce excessive ketones if his or her food intake that day consisted only of
|
a. |
green salad with oil and vinegar dressing. |
|
b. |
refried pinto beans and rice. |
|
c. |
cheeseburgers and French fries. |
|
d. |
fried eggs with bacon and hash brown potatoes. |
ANS: A
Ketones are produced when insufficient carbohydrate is available and the body has to metabolize fat for energy. A green salad with oil and vinegar dressing provides energy from fat but minimal amounts of carbohydrates. In the other meals, carbohydrate is provided by beans, rice, the bun for the burger, and the potatoes used to make the fries and hash browns.
