Accepted Answer

Lactovegetarians include dairy products (foods in the milk group) in their diets but do not eat meat, fish, poultry, or eggs.

Question 2

Macronutrients

Accepted Answer

Macronutrients, which include carbohydrates, fats, proteins, and water, are essential for energy, growth, and development of body tissues. Water, while not providing energy, is crucial for many bodily functions.

Question 3

What is the term used to describe the average daily dietary intake that is sufficient to meet the nutrient requirement of nearly all healthy individuals?

Accepted Answer

The Recommended Dietary Allowance (RDA) is the average daily dietary intake level that is sufficient to meet the nutrient requirement of nearly all (97 to 98 percent) healthy individuals in a particular life stage and gender group.

Question 4

What is the term used to describe the recommended daily nutrient intake level based on observed or experimentally determined approximations of nutrient intake by a group of healthy people?

Accepted Answer

Adequate Intake (AI) is the term used when an RDA cannot be determined. AI is based on observed or experimentally determined estimates of nutrient intake by a group of healthy people and is used when there is not enough evidence to develop an RDA.

Question 5

Which statement about the typical American diet is FALSE?

Accepted Answer

Most Americans do not obtain adequate amounts of calcium in their diet, contrary to the statement in option C. The typical American diet is often criticized for its high content of saturated fats, excessive calorie intake, and insufficient fiber, but not for adequate calcium intake.

Question 6

The recommended daily dietary goal for cholesterol intake is no more than

Accepted Answer

The recommended daily dietary goal for cholesterol intake is no more than 300mg, according to guidelines aimed at promoting heart health and reducing the risk of heart disease.

Question 7

One example of a micronutrient is

Accepted Answer

Micronutrients include vitamins and minerals, which are essential for the body in small amounts.

Question 8

The Dietary Reference Intake (DRI) consists of which of the following reference intakes?

Accepted Answer

The Dietary Reference Intake (DRI) includes four reference values: Recommended Dietary Allowance (RDA), Adequate Intake (AI), Tolerable Upper Intake Level (UL), and Estimated Average Requirement (EAR).

Question 9

Of the following statements, which is true of a healthy vegetarian diet?

Accepted Answer

A healthy vegetarian diet can supply an adequate amount of nutrients while being relatively low in caloric content, provided it is well-planned.

Question 10

A good example of a nonessential nutrient is

Accepted Answer

Creatine is a nonessential nutrient because the body can synthesize it from amino acids, meaning it does not need to be obtained through the diet.

Question 11

Food manufacturers may make health claims under the new labeling regulations because the FDA believes that there may be sufficient scientific data supporting a relationship

Accepted Answer

The FDA allows health claims on food labels when there is sufficient scientific evidence to support a relationship between the consumption of a specific nutrient and the possible prevention of certain chronic diseases. This approach is intended to help consumers make more informed choices about their diets.

Question 12

Nutrients that the body needs, but cannot produce in adequate quantities are called

Accepted Answer

Essential nutrients are substances that the body needs but cannot produce on its own in sufficient amounts. These must be obtained through diet.

Question 13

According to the National Academy of Sciences, fat should provide of overall Calories in the diet.

Accepted Answer

Accepted Answer

Soybeans are a good source of lysine, an essential amino acid that is low in rice, making them complementary for a complete protein profile.

Question 19

When considering the key-nutrient concept, which of the following is NOT true?

Accepted Answer

The key-nutrient concept emphasizes the importance of obtaining nutrients from whole, minimally processed foods rather than relying on highly processed foods that have been fortified with vitamins. This approach suggests that a diet rich in a variety of whole foods is more likely to provide all essential nutrients in adequate amounts.

Question 20

Nutrient density

Accepted Answer

Nutrient density refers to how many nutrients you get from a food, given the number of calories it contains.
