Question 1

The Dietary Guidelines for Americans is published by the U.S. Department of Agriculture.

Accepted Answer

The Dietary Guidelines for Americans is published jointly by the U.S. Department of Agriculture (USDA) and the Department of Health and Human Services (HHS).

Question 2

Adequate intake (AI)values are based not only on the available scientific evidence but also on some educated guesswork.

Accepted Answer

Adequate Intake (AI) values are indeed based on both the available scientific evidence and some educated guesswork, especially when sufficient scientific evidence is lacking to establish a more precise Recommended Dietary Allowance (RDA).

Question 3

The Daily Values are nutrient standards used to compare the nutrient contents of packaged foods.

Accepted Answer

The Daily Values are indeed nutrient standards set by regulatory authorities that are used on food labels to help consumers compare the nutrient contents of different packaged foods and understand how those foods fit into their overall diet.

Question 4

If a nutrient does not have a Tolerable Upper Intake Level, this means that:

Accepted Answer

Insufficient data exist to establish a value for the Tolerable Upper Intake Level (UL) when it is not provided, indicating a lack of enough scientific evidence to determine a maximum level that is unlikely to pose risks of adverse health effects in the general population.

Question 5

Dietary Reference Intakes (DRI)are nutrient standards used on food labels and on grocery store signs.

Accepted Answer

Dietary Reference Intakes (DRI) are a set of reference values used to plan and assess nutrient intakes of healthy people. They are not specifically used on food labels or grocery store signs; those often use the Daily Value (DV) or Recommended Daily Allowance (RDA) for nutrient information.

Question 6

Varying food choices among and within food groups in the USDA Eating Patterns helps ensure adequate nutrient intakes and protects against consuming large amounts of toxins or contaminants from any one food.

Accepted Answer

Varying food choices helps to ensure a balanced intake of nutrients while minimizing the risk of overexposure to potential toxins or contaminants that might be present in higher amounts in certain foods.

Question 7

Which of the following establishes the average nutrient requirements for given life stages and gender groups used by nutrition policy makers?

Accepted Answer

Estimated Average Requirements (EARs) are used to assess the nutrient intakes of populations and are the average daily nutrient intake level estimated to meet the requirement of half the healthy individuals in a particular life stage and gender group. This makes them useful for nutrition policy makers in establishing guidelines.

Question 8

According to the Dietary Guidelines for Americans 2015 - 2020, choosing a healthy eating pattern at an appropriate calorie level helps in reducing the risk of chronic disease.

Accepted Answer

The Dietary Guidelines for Americans 2015 - 2020 emphasize that choosing a healthy eating pattern at an appropriate calorie level is crucial for health promotion and disease prevention, including reducing the risk of chronic diseases such as heart disease, diabetes, and obesity.

Question 9

"Diets low in sodium may reduce the risk of high blood pressure" is an example of a health claim allowed on a food label and is reliable because the FDA has substantial scientific support for the claim.

Accepted Answer

The FDA allows certain health claims that are supported by scientific evidence, including the claim that diets low in sodium may reduce the risk of high blood pressure, as there is substantial scientific agreement on this relationship.

Question 10

Which of the following statements is incorrect about the Dietary Reference Intakes (DRI)?

Accepted Answer

Dietary Reference Intakes (DRI) are not just minimum requirements; they are a set of reference values used to plan and assess nutrient intakes of healthy people. These values include Recommended Dietary Allowances (RDA), which are average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%-98%) healthy people, and Adequate Intakes (AI), which are used when RDA cannot be determined. Therefore, DRIs are indeed recommendations rather than mere minimum requirements.

Question 11

Identify a characteristic of the Dietary Reference Intakes (DRI).

Accepted Answer

The Dietary Reference Intakes (DRI) are designed to reflect daily intakes that should be achieved on average over time. This approach acknowledges that people's daily intake of nutrients may vary but aims for a balanced intake over a longer period.

Question 12

The absence of a Tolerable Upper Intake Level for a nutrient implies that it is safe to consume in any amount.

Accepted Answer

The absence of a Tolerable Upper Intake Level (UL) for a nutrient does not necessarily mean it is safe to consume in any amount; it may indicate that insufficient data exists to establish a safe upper limit.

Question 13

Users of the Food Lists for Diabetes and Weight Management can make an informed approximation of the energy-yielding nutrients and calories in almost any food they might encounter.

Accepted Answer

The Food Lists for Diabetes and Weight Management categorize foods based on their nutritional content, allowing users to estimate the macronutrients and caloric value of various foods, aiding in better dietary planning and management.

Question 14

One of the major disadvantages of the USDA Eating Patterns is that they cannot be adapted to other national and cultural cuisines.

Accepted Answer

The USDA Eating Patterns are designed to be adaptable to include foods from various national, regional, and cultural cuisines, allowing for flexibility in dietary choices while still meeting nutritional needs.

Question 15

The Dietary Reference Intakes (DRI)are international guidelines that are used around the world.

Accepted Answer

The Dietary Reference Intakes (DRI) are specific to the United States and Canada, developed by the National Academies of Sciences, Engineering, and Medicine to guide nutrition and health professionals in these countries.

Question 16

The Dietary Reference Intakes (DRI)committee recommends a diet that provides _____ percent of its calories from carbohydrate.

Accepted Answer

The Dietary Reference Intakes (DRI) committee recommends a diet that provides 45-65 percent of its calories from carbohydrate to support energy needs and nutritional adequacy.

Question 17

An important recommendation of the Dietary Guidelines for Americans 2015 - 2020 is to make physical activity a habit.

Accepted Answer

The Dietary Guidelines for Americans 2015 - 2020 emphasize the importance of physical activity as part of a healthy lifestyle, recommending that individuals make it a regular habit for overall health benefits.

Question 18

What are the Dietary Reference Intakes (DRI)designed for?

Accepted Answer

Dietary Reference Intakes (DRI) are designed for disease prevention in healthy people by providing guidelines on the intake of nutrients to maintain health and prevent chronic diseases, rather than treating or reversing conditions.

Question 19

There is strong scientific evidence that individual phytochemical supplements safely provide health benefits.

Accepted Answer

Most scientific evidence suggests that the health benefits attributed to phytochemicals are best obtained through whole food consumption rather than individual supplements, which may not provide the same benefits and could potentially pose health risks.

Question 20

Acceptable Macronutrients Distribution Ranges refer to healthy ranges of intake for carbohydrate, fat, and protein.

Accepted Answer

Acceptable Macronutrient Distribution Ranges (AMDRs) are guidelines that provide healthy ranges of intake for carbohydrates, fats, and proteins, aimed at balancing diet to prevent nutrition-related diseases.
