Question 1

The bottom portion of the Nutrition Facts panel on a food package:

Accepted Answer

The bottom portion of the Nutrition Facts panel is identical on every label and lists the Daily Values standards.

Question 2

Any food providing 10%-19% of the Daily Value for a nutrient is considered to be a _____ source of the nutrient.

Accepted Answer

A food providing 10%-19% of the Daily Value for a nutrient is considered to be a "good" source of that nutrient.

Question 3

When referring to the DRI recommended intakes, it is important to remember that:

Accepted Answer

The Dietary Reference Intakes (DRIs) are based on the latest available scientific research to provide guidelines for nutrient intake to maintain health and prevent deficiencies.

Question 4

George is a 35-year-old athlete using nutrient supplements to give him a competitive advantage. Which of the following nutrient intake recommendations would you suggest that George become familiar with?

Accepted Answer

Tolerable Upper Intake Levels (ULs) are the maximum daily intakes of nutrients that are unlikely to cause adverse health effects in almost all individuals within a population. As an athlete using nutrient supplements, George is at risk of consuming excessive amounts of nutrients, which can be harmful to his health. Therefore, familiarizing himself with the Tolerable Upper Intake Levels is vital to ensure he does not consume excessive amounts of nutrients. Adequate Intakes, Estimated Average Requirements, and Recommended Dietary Allowances are not as relevant for George's situation.

Question 5

In exchange lists, foods are categorized by:

Accepted Answer

In exchange lists, foods are categorized by the average nutrient values in grams for whole groups of foods. This allows individuals to easily choose foods from a particular group based on their desired nutrient intake without having to memorize the exact nutrient values for each food item.

Therefore, the best choice is C.

Question 6

Your sister has evaluated her usual diet by comparing it to the U.S. Dietary Guidelines and has found that her intakes of fruits, vegetables, and dairy foods are lower than recommended. How would you interpret her results?

Accepted Answer

The U.S. Dietary Guidelines recommend consuming a variety of fruits, vegetables, and dairy foods daily. If her intakes of these food groups are lower than recommended, she needs to eat more of these foods and possibly cut back on other foods to balance her calorie intake.

Question 7

When creating and evaluating meals on a daily basis it is best to:

Accepted Answer

While the DRI and USDA Food Patterns can be helpful tools in creating and evaluating meals, they should not be the sole source of information. Computerized diet analysis programs can also be useful, but they may not always provide accurate information. Using a combination of analysis tools, such as these, can provide the most accurate assessment of nutrient adequacy.

Question 8

All of the following are characteristics of exchange systems except:

Accepted Answer

Exchange systems sort foods by their carbohydrate, protein, and fat contents, not just their carbohydrate contents.

Question 9

The MyPlate educational tool has been designed to:

Accepted Answer

The MyPlate educational tool has been designed to help a diet-planning individual create a diet that more closely follows the USDA Food Patterns. It provides guidance on the types and amounts of food to eat from different food groups to form a balanced and healthy diet. It does not create an alternative diet plan nor substitute for the recommendations of the Dietary Guidelines for Americans in diet planning. It can be helpful for individuals who need to make major changes in their diet for chronic disease control, but it is not designed specifically for this purpose.

Question 10

Concerned about the toxic effects of added nutrients in fortified foods and supplements, when eaten in addition to staple foods, scientists established the _____ category of the Dietary Reference Intakes (DRI).

Accepted Answer

The Tolerable Upper Intake Levels (UL) category was established to address concerns about the potential toxicity of overconsumption of added nutrients. This category sets the maximum daily intake of a nutrient that is unlikely to result in adverse health effects for almost all individuals in a population.

Question 11

Which of the following people would not be covered by the DRI, based on assumptions made by the DRI committee?

Accepted Answer

The DRI committee takes into consideration the specific nutritional needs of individuals with medical conditions. Cystic fibrosis is a disease that affects the digestive system and requires a specialized diet, which would not be covered by the general DRI guidelines. The other individuals (A, B, and D) would be covered by the DRI guidelines as they do not have any medical conditions that would require specific nutritional recommendations.

Question 12

The implications of the U.S. Dietary Guidelines include all of the following except:

Accepted Answer

The U.S. Dietary Guidelines recommend healthy eating patterns and nutrient-dense foods, but they do not necessarily require detailed meal planning. Rather, the guidelines prioritize a balance of food groups and portion sizes, and emphasize the importance of incorporating physical activity into one's daily routine.

Question 13

When public health officials were determining the amount of folate to add to grain products in the food supply for fortification, they most likely reviewed which of the following values for that particular vitamin for women of child-bearing age?

Accepted Answer

The Estimated Average Requirements (EAR) value for folate for women of child-bearing age was most likely reviewed by public health officials when determining the amount of folate to add to grain products for fortification. The EAR represents the estimated average daily nutrient intake level that meets the requirement of half the healthy individuals in a particular life stage and gender group. It is used to establish the Recommended Dietary Allowance (RDA) for a nutrient. Since the primary purpose of folate fortification is to prevent neural tube defects in infants, the focus is on women of child-bearing age who may become pregnant.

Question 14

When comparing the two categories of nutrient standards, the Dietary Reference Intakes and the Daily Values, one difference between the two is:

Accepted Answer

The Daily Values are specific to the United States and are used on food labels to help consumers understand the nutrient content of a food item in the context of a total daily diet.

Question 15

The percentages of the Daily Values on food packages are given in terms of a person requiring _____ calories each day.

Accepted Answer

The Daily Values on food packages are based on a person requiring 2,000 calories each day, so the best choice is A. It is important to note that individual calorie needs may vary depending on factors such as age, gender, height, weight, and physical activity level.

Question 16

Which of the following foods is exempt from listing ingredients on the label?

Accepted Answer

All foods are required to list ingredients on the label, regardless of their type or classification.

Question 17

Amounts of which types of lipids must be listed on food labels?

Accepted Answer

According to FDA regulations, trans fat and cholesterol must be listed on food labels. Monounsaturated and other types of fats are not required to be listed.

Question 18

Exchange systems help primarily with:

Accepted Answer

Exchange systems are designed to help with calorie control by categorizing foods into groups with similar nutritional values, allowing individuals to manage their intake more effectively.

Question 19

A person is trying to eat the best diet to reduce the risk of developing chronic disease. She wants to be sure that she will consume adequate nutrients in the best proportions from her foods she selects. Which would be the best DRI recommendation for her to use to ensure she has the best energy nutrient intakes to reduce chronic disease risk?

Accepted Answer

The Acceptable Macronutrient Distribution Ranges (AMDR) provide guidelines on the percentage of daily calorie intake that should come from carbohydrates, fats, and proteins. Following these ranges can help ensure that a person is consuming adequate nutrients in the best proportions from the foods they select. This is particularly important for reducing the risk of chronic disease, as an unbalanced intake of macronutrients (either too much or too little) has been linked to an increased risk of chronic disease. The Recommended Dietary Allowances (RDA) and Adequate Intakes (AI) provide guidance on individual nutrients, but do not provide the same level of guidance on overall energy nutrient intake. Daily Values (DV) are used as a reference for food labeling and are not specific to individual needs.

Question 20

Your grandfather has been advised by a neighbor to select his foods using the Dietary Guidelines for Americans to help cure his high blood pressure. What advice would you give him?

Accepted Answer

The Dietary Guidelines for Americans can provide general advice for healthy eating, but for specific health conditions like high blood pressure, it's important to consult a healthcare provider for personalized recommendations.
