People with hypoglycemia should eat balanced snacks that include complex carbohydrates, proteins, and healthy fats to maintain stable blood sugar levels, rather than relying on simple sugars which can cause spikes and crashes.

Question 3

The primary role of fiber in the diet is to provide quick energy.

Accepted Answer

Fiber's primary role is to aid in digestion and maintain bowel health, not to provide quick energy.

Question 4

Carbohydrate-rich foods are obtained almost exclusively from plants.

Accepted Answer

Most carbohydrate-rich foods, such as grains, fruits, and vegetables, are derived from plants, with few exceptions like lactose from milk.

Question 5

What is the condition in which the body is unable to digest lactose?

Accepted Answer

Question 6

The body's form of stored glucose is called glucagon.

Accepted Answer

Glucagon is a hormone that raises blood glucose levels, while glycogen is the stored form of glucose in the body.

Question 7

The protein in a meal stimulates glycogen secretion, which opposes insulin and prevents it from storing glucose.

Accepted Answer

Protein in a meal stimulates glucagon secretion, not glycogen. Glucagon opposes insulin by promoting the release of glucose into the bloodstream, while insulin promotes the storage of glucose.

Question 8

Carbohydrate digestion begins in the mouth.

Accepted Answer

Carbohydrate digestion begins in the mouth with the enzyme amylase, which breaks down complex carbohydrates into simpler sugars.

Question 9

Fat is used efficiently as fuel by the brain and nerves.

Accepted Answer

The brain and nerves primarily use glucose as their source of energy and have a limited ability to metabolize fats directly. Ketone bodies, produced from fats during periods of low carbohydrate intake, can be used as an alternative energy source by the brain, but fats themselves are not directly utilized efficiently.

Question 10

For certain body systems,  ____ are the preferred energy source and are the ideal fuel for the body.

Accepted Answer

Carbohydrates are the body's preferred energy source, especially for the brain and muscles during exercise, as they are easily converted into glucose.

Question 12

What is another name for low blood glucose?

Accepted Answer

Hypoglycemia is the medical term for low blood glucose levels.

Question 13

What are the two major types of complex carbohydrates?

Accepted Answer

Question 17

When a person is hungry and needs to replenish blood glucose, s/he should eat ____.

Accepted Answer

Carbohydrates, protein, and fats provide a balanced source of energy and nutrients, helping to replenish blood glucose and sustain energy levels.

Question 18

Babies develop the ability to digest lactose when they are about six to nine months old.

Accepted Answer

Babies are born with the ability to digest lactose, as it is the primary sugar found in breast milk, which is essential for their nutrition from birth.

Question 19

Adding foods sweetened with sugar substitutes to the diet will ensure successful weight loss.

Accepted Answer

While sugar substitutes may reduce overall calorie intake, research has shown that they may actually increase food cravings and lead to overeating. Additionally, some studies suggest potential health risks associated with long-term consumption of certain sugar substitutes. Therefore, relying solely on sugar substitutes to promote weight loss may not be effective or healthy in the long run. A balanced and nutritious diet, along with regular physical activity, is a more sustainable approach to weight management.

Question 20

Soluble fibers help lower blood cholesterol levels.
