Question 1

Which statement best describes the healthful diet principle of moderation?

Accepted Answer

Moderation involves paying attention to portion sizes and ensuring that you do not overconsume nutrients and kilocalories. Option C describes this principle accurately. Option A describes the principle of variety, option B describes the principle of balance, and option D describes the principle of nutrient density.

Question 2

A food label states that a serving of a particular product provides 20 percent of the Daily Value for fat. This means that

Accepted Answer

B

Question 3

According to MyPlate, an adult age 18 or older should consume how many cups of milk or milk equivalents per day on a 2,000-calorie diet?

Accepted Answer

MyPlate recommends that adults on a 2,000-calorie diet consume 3 cups of milk or milk equivalents per day to ensure adequate intake of calcium and other essential nutrients.

Question 4

Which statement best describes nutrient density?

Accepted Answer

Nutrient density refers to the amount of nutrients present in a food in relation to the amount of calories it provides. Foods that are nutrient-dense are those that provide a lot of valuable nutrients (such as vitamins and minerals) relative to the energy/calorie content. Therefore, consuming foods that have the most nutrients when compared to their kilocalories is the best way to ensure a diet that is nutrient-dense.

Question 5

According to MyPlate, consumption of foods from the Grains group should include

Accepted Answer

MyPlate recommends that at least half of the grain servings should come from whole grain sources such as whole grain cereals, breads, crackers, rice, or pasta, every day. This ensures intake of essential nutrients, fiber, and other health-promoting compounds found in whole grains. However, the other half can come from refined grain products as well, but it is important to make sure that they are enriched or fortified with essential nutrients like iron and folic acid. Therefore, option B is the best choice.

Question 6

The acronym RDA stands for

Accepted Answer

RDA stands for Recommended Dietary Allowance, which refers to the average daily level of intake sufficient to meet the nutrient requirements of nearly all (97–98%) healthy people.

Question 7

The RDAs for nutrients generally are

Accepted Answer

The RDAs (Recommended Dietary Allowances) for nutrients are designed to be adequate for almost all healthy people. They are set to cover the needs of 97-98% of the population, taking into account age, gender, and other factors. This means that if you meet the RDA for a particular nutrient, you are most likely getting enough to meet your body's needs.

Question 8

Tina is consuming 15 mg of iron per day. Her RDA is 18 mg. She has no condition warranting a greater-than-normal need for iron. Which of the following statements is true about her consumption of this nutrient?

Accepted Answer

Tina is not consuming the recommended daily allowance (RDA) of 18 mg of iron. However, she is not necessarily deficient in iron, as her intake is only slightly below the recommended amount. According to the Institute of Medicine, an intake of at least 70% of the RDA is generally considered adequate to meet the needs of most individuals. Therefore, unless her intake consistently falls below 70% of the RDA, Tina is not at great risk of nutritional deficiency. She may need to consume slightly more iron to reach the RDA, but not significantly more.

Question 9

Measurements of height, weight, body circumferences, and body fat are called

Accepted Answer

Measurements of height, weight, body circumferences, and body fat are called anthropometry. Sonography is a medical imaging technique that uses sound waves to visualize organs and tissues in the body, electrocardiography is a test that records the electrical activity of the heart, and echocardiography is a type of ultrasound that uses sound waves to create images of the heart.

Question 10

Which of the following measures does NOT assess nutritional status?

Accepted Answer

The measure that does NOT assess nutritional status is psychoanalysis, as it is a form of therapy for mental health issues and is not related to dietary or biochemical evaluations.

Question 11

Which of the following is true about the way we should eat to achieve good nutritional status?

Accepted Answer

Eating a wide variety of foods is essential for good nutritional status as no single natural food can provide all the nutrients we need. While fruits and vegetables are important, they do not provide all the necessary nutrients. Taking supplements to fill in deficient areas is not the preferred approach, as it is always best to get nutrients from actual foods. Finally, animal products can provide important nutrients, but it is important to choose leaner cuts of meat and dairy products low in saturated fats.

Question 12

Which term describes failing health that results from a long-standing dietary intake that is inadequate to meet nutritional needs?

Accepted Answer

Undernutrition is the term used to describe failing health that results from a long-standing dietary intake that is inadequate to meet nutritional needs. Desirable, balanced, and inferior nutrition are not specific terms used to describe this condition.

Question 13

Ann Miles, a triathlete, wants to eat a health-promoting diet and achieve dietary adequacy. Which of the following behaviors exemplifies the concept of dietary moderation?

Accepted Answer

Moderation involves balancing food choices, such as compensating for a high-fat, high-sodium meal with a lower-fat, lower-sodium meal later.

Question 14

The term "Daily Values" on a food label refers to

Accepted Answer

Daily Values are a generic standard set at or close to the highest RDA value or related nutrient standard. They are used as a reference for the amount of nutrients and calories needed in a day and are based on a 2,000 calorie diet. This allows consumers to easily compare different foods and make informed decisions about their diet.

Question 15

The RDAs are considered to be adequate to meet the known nutritional needs of

Accepted Answer

The RDAs are designed to meet the nutrient needs of nearly all healthy persons. However, there may be certain individuals with unique needs (such as pregnant or lactating women) who require higher intakes and may need to exceed the RDA. The RDAs may also not be adequate for individuals with certain medical conditions or those taking certain medications.

Question 16

Adequate Intakes (AI)

Accepted Answer

Adequate Intakes (AI) are established for nutrients for which there is not enough information to set RDAs.

Question 17

The RDAs for nutrients are set

Accepted Answer

The Recommended Dietary Allowances (RDAs) are set to meet the nutrient needs of 97% - 98% of the healthy population.

Question 18

Which meal contains foods from all food groups represented in MyPlate?

Accepted Answer

The meal of refried beans, onions, tomatoes, and cheddar cheese wrapped in a tortilla, orange and water has foods from all the food groups represented in MyPlate. The tortilla provides grains, refried beans provide protein, onions and tomatoes provide vegetables, cheddar cheese provides dairy, and the orange provides fruit.

Question 19

You pick up a box of Cheerios cereal in the supermarket. The Nutrition Facts panel tells you that a 1-cup serving provides 25 percent of the ______ for iron.

Accepted Answer

The Daily Value (DV) is the percentage of recommended daily intake of a nutrient that can be found in a serving of food. The RDA (A) is the average daily intake level that meets the nutrient needs of 97-98% of healthy individuals, and the Minimum Requirement (C) is the minimum amount of a nutrient that must be consumed to prevent deficiency. The ESADDI (D) is the Estimated Safe and Adequate Daily Dietary Intake, which is an older term that is no longer used.

Question 20

One serving of Raisin Bran cereal contains 50 percent of the 18 mg Daily Value for iron. How much iron will one serving of your cereal provide?

Accepted Answer

Since one serving of Raisin Bran cereal provides 50 percent of the 18 mg Daily Value for iron, that means it provides 9 mg of iron (50% of 18 mg).
