Question 1

The 2015-2020 Dietary Guidelines for Americans focus on three examples of healthy eating patterns.Which one of the following was NOT included?

Accepted Answer

The Healthy Paleolithic Eating Pattern was not included in the 2015-2020 Dietary Guidelines for Americans. The other three options listed were included as examples of healthy eating patterns.

Question 2

Which of the following is the highest level of daily nutrient intake that is likely to pose no risk of adverse health effects to almost all apparently healthy individuals in the general population?

Accepted Answer

The Tolerable Upper Intake Level (UL) is the highest level of daily nutrient intake that is established to pose no risk of adverse health effects to almost all apparently healthy individuals in the general population. It is the maximum amount of a nutrient that can be consumed daily without causing harm in nearly all individuals.

Question 3

On May 20,2016,the FDA announced the new Nutrition Facts label for packaged foods.Which one of the following updates to the Nutrition Facts label was mandated by 2018?

Accepted Answer

The FDA mandated an increase in the type size for "Calories" to make this information more prominent and easier for consumers to find and read.

Question 4

The primary focus of the 2015-2020 Dietary Guidelines for Americans is ________.

Accepted Answer

The primary focus of the 2015-2020 Dietary Guidelines for Americans is promoting a healthy eating pattern, which includes a variety of nutrient-dense foods, while limiting added sugars, saturated fats, and sodium. While increasing intake of shortfall nutrients (like calcium, potassium, and vitamin D) and decreasing intake of saturated fats and cholesterol are important recommendations within the guidelines, they are not the primary focus.

Question 5

Which one of the following statements about early,observational dietary standards and guidelines is false?

Accepted Answer

Early observational dietary standards and guidelines were not developed from calorimetry and nitrogen balance studies on humans. Instead, they were based on observations of what people ate and what health outcomes resulted from those diets.

Question 6

The recommended intakes for most nutrients for infants up to age 1 year are expressed in terms of ________.

Accepted Answer

The recommended intakes for most nutrients for infants up to age 1 year are expressed in terms of Adequate Intake (AI) because the other options (Estimated Average Requirement, Recommended Dietary Allowance, and Tolerable Upper Intake Level) are not appropriate for infants due to limited data on nutrient requirements and potential toxicity. The AI is based on observed or experimentally determined approximations of nutrient intake by a group or groups of apparently healthy people that are assumed to be adequate.

Question 7

Broccoli dipped in batter and deep-fat fried would have ________ nutrient density compared to steamed broccoli,lightly salted,and served with a lemon wedge.

Accepted Answer

Deep-fat frying increases the calorie content and decreases the nutrient content of the food, therefore reducing its nutrient density compared to steamed and lightly seasoned broccoli.

Question 8

Which one of the following is NOT one of the five general guidelines for the 2015-2020 Dietary Guidelines for Americans?

Accepted Answer

The five general guidelines for the 2015-2020 Dietary Guidelines for Americans are to follow a healthy eating pattern across the lifespan, focus on variety, nutrient density, and amount, limit calories from added sugars and saturated fats and reduce sodium intake, shift to healthier food and beverage choices, and support healthy eating patterns for all. None of the guidelines mention specifically focusing on foods with high levels of antioxidant nutrients.

Question 9

Which of the following options correctly represents the chronological sequence in the development of the three graphic food guides listed?

Accepted Answer

The Food Guide Pyramid was first developed in 1992, followed by the MyPyramid in 2005. MyPlate was introduced in 2011, making the correct chronological sequence: Food Guide Pyramid; MyPyramid; MyPlate.

Question 10

Which of the following is a nutrient whose intake is less than the recommended intake level for a significant part of the population?

Accepted Answer

A nutrient whose intake is less than the recommended intake level for a significant part of the population is called a shortfall nutrient. This means that many people are not getting enough of this nutrient in their diet, which can lead to health problems. Examples of shortfall nutrients include calcium, vitamin D, and potassium.

Question 11

The food labeling values established by the Food and Drug Administration for use in the Nutrition Facts panel are known as ________.

Accepted Answer

The Daily Values are the food labeling values established by the Food and Drug Administration for use in the Nutrition Facts panel. The U.S. Dietary Goals and Dietary Guidelines for Americans are general recommendations for healthy eating, while Dietary Reference Intakes are specific nutrient intake recommendations for different populations.

Question 12

Which of the following is the nutrient intake level sufficient to meet the nutrient requirements of approximately 97% of people in a given sex/age group?

Accepted Answer

Recommended Dietary Allowance (RDA) is the nutrient intake level sufficient to meet the nutrient requirements of approximately 97% of people in a given sex/age group. RDA is based on the Estimated Average Requirement (EAR) with additional safety factors. Adequate Intake (AI) is used when there is insufficient scientific evidence to establish RDA, while Tolerable Upper Intake Level (UL) is the highest level of nutrient intake that is unlikely to cause adverse health effects.

Question 13

The recommendations contained within the Dietary Guidelines for Americans are applicable to the general public living in the United States ________.

Accepted Answer

The Dietary Guidelines for Americans are designed to be applicable starting at about two years of age, focusing on providing nutritional guidance that supports healthy growth and development from toddlerhood onward. Prior to this age, specific dietary recommendations, such as exclusive breastfeeding for the first 6 months, are typically advised.

Question 14

Which one of the following was developed by the USDA for assessing the quality of the diets of Americans?

Accepted Answer

The Healthy Eating Index was developed by the USDA to assess the quality of diets of Americans based on recommended dietary guidelines. The index takes into account various factors such as consumption of fruits, vegetables, whole grains, dairy, protein foods, added sugars, saturated fats, and sodium.

Question 15

Which one of the following statements is true about the nutrition recommendations developed by Carl Voit and Wilber Atwater?

Accepted Answer

The answer of Which one of the following statements is...

Question 16

The ________ system is a method of planning meals that simplifies controlling energy consumption (particularly from carbohydrate),helps ensure adequate nutrient intake,and allows considerable variety in food selection.

Accepted Answer

The Choose Your Foods system is a method of meal planning that simplifies controlling energy consumption, helps ensure adequate nutrient intake, and allows for variety in food selection. The other options listed (Dietary Guidelines for Americans, DRIs, and Daily Values) are not meal planning systems, but rather tools used to guide nutrient intake or inform dietary recommendations.

Question 17

Which one of the following represents the point of nutrient intake at which one half of the members of a given group will have its nutrient needs met while the remaining half will not?

Accepted Answer

The Estimated Average Requirement (EAR) represents the point of nutrient intake at which one half of the members of a given group will have their nutrient needs met while the other half will not. It is used to establish the Recommended Dietary Allowance (RDA) and is based on scientific research. The Adequate Intake (AI) is used when there is not enough data available to establish an EAR or RDA, and the Tolerable Upper Intake Level (UL) is the highest level of nutrient intake that is safe for most people.

Question 18

The ________ are dietary reference values intended to help consumers use food label information to plan healthy diets.

Accepted Answer

Daily Values are the dietary reference values used on food labels to help consumers make informed choices about their diets. The Dietary Guidelines for Americans are recommendations for overall healthy eating habits, DRIs (Dietary Reference Intakes) are a set of reference values for nutrient intake, and EARs (Estimated Average Requirements) are the amount of a nutrient that is estimated to meet the needs of half of the healthy individuals in a specific group.

Question 19

Which of the following is the recommended daily dietary intake level that is assumed to be adequate and that is based on experimentally determined approximations of observed nutrient intake by a group of healthy people?

Accepted Answer

Adequate Intake is the recommended daily dietary intake level that is assumed to be adequate and that is based on experimentally determined approximations of observed nutrient intake by a group of healthy people. Estimated Average Requirement (A) is the intake level for a nutrient at which the needs of 50% of the population will be met. Recommended Dietary Allowance (C) is the amount of a nutrient that is sufficient to meet the needs of almost all (97-98%) healthy individuals in a specific age and gender group. Tolerable Upper Intake Level (D) is the highest level of a nutrient intake that is unlikely to pose a risk of adverse health effects to almost all individuals in a specific age and gender group.

Question 20

Which one of the following was developed to assist persons with diabetes in planning their diets?

Accepted Answer

The Food Exchange System was developed specifically for persons with diabetes to assist them in planning their diets by categorizing foods into exchange groups based on their macronutrient content. The other options are general dietary guidelines and reference values that apply to the general population.
