Question 1

When referring to the Dietary Reference Intakes (DRI)recommendations, it is important to remember that:

Accepted Answer

The Dietary Reference Intakes (DRI) recommendations are based on the latest available scientific research to provide guidance on the intake of nutrients to support health. They are not specifically for recovery from illness, updated by non-scientific communities, required to be consumed on alternate days, nor are they non-specific regarding age or gender.

Question 2

A group of public health officials are trying to determine the amount of folate to be added to fortify grain products for women of child-bearing age. Which of the following nutrient standards are the officials most likely to use?

Accepted Answer

Estimated Average Requirements (EAR) are used to determine the amount of a nutrient needed to meet the requirements of half of the healthy individuals in a group. This is useful for setting recommendations for populations, such as determining the amount of a nutrient to add to foods for fortification purposes.

Question 3

According to the Dietary Guidelines for Americans , who among the following cannot enjoy the best possible health?

Accepted Answer

The Dietary Guidelines for Americans suggest that overconsuming calories and proteins can lead to health issues such as obesity, heart disease, and other conditions, thus not allowing individuals to enjoy the best possible health.

Question 4

Any food providing 10 to 19% of the Daily Value for a nutrient in one serving is considered to be a(n)_____ source of the nutrient.

Accepted Answer

Foods that provide 10 to 19% of the Daily Value for a nutrient in one serving are considered to be a good source of that nutrient.

Question 5

Which of the following is recommended by the USDA's Physical Activity Guidelines for Americans?

Accepted Answer

The USDA's Physical Activity Guidelines for Americans recommend that adults engage in at least 150 minutes (2.5 hours) of moderate-intensity physical activity each week, which aligns with choice C.

Question 6

A person is trying to follow the best diet to reduce the risk of developing chronic disease. She wants to make sure that she consumes adequate nutrients in the best proportions from the foods she selects. Which would be the best Dietary Reference Intakes (DRI)standards for her to use to ensure she has the best energy nutrient intakes to reduce chronic disease risk?

Accepted Answer

Acceptable Macronutrient Distribution Ranges (AMDR) are designed to provide ranges of intake for different energy nutrients (carbohydrates, proteins, and fats) that are associated with reduced risk of chronic diseases while providing adequate intakes of essential nutrients.

Question 7

According to the USDA Eating Patterns, which of the following includes the recommended daily amounts of nutrient-dense food from each group for a sedentary, 32-year-old woman who requires 2,000 kcal\day?

Accepted Answer

The USDA dietary guidelines recommend a balanced intake of fruits, vegetables, grains, protein foods, dairy, and oils. Choice B closely aligns with these recommendations for a sedentary woman requiring 2,000 kcal/day, offering a balanced and nutrient-dense selection from each food group.

Question 8

When you see that foods have a high nutrient density, you should:

Accepted Answer

High nutrient density foods are rich in vitamins, minerals, and other nutrients important for health, without being high in calories. The USDA Eating Patterns recommend these foods as they provide essential nutrients while helping to maintain a healthy weight and overall health.

Question 9

Which of the following best fits into a meal plan for a person who must eat 1 cup vegetables, 2 ounces grains, and 2 ounces protein foods at lunch?

Accepted Answer

This option provides 1 cup of vegetables (bean salad), 2 ounces of grains (1 cup cooked rice), and 2 ounces of protein foods (1/2 cup tofu).

Question 10

According to the USDA Eating Patterns, one teaspoon (tsp)oil is equal to:

Accepted Answer

One teaspoon of oil is equivalent to one teaspoon of soft margarine according to the USDA Eating Patterns. This is because both provide a similar amount of fat and calories, fitting into the same category of fats and oils in dietary guidelines.

Question 11

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

Accepted Answer

She needs to increase her intake of fruits, vegetables, and dairy to meet the USDA recommendations, while ensuring her overall calorie intake remains balanced.

Question 12

Tea and certain spices are not included in the USDA Eating Patterns. Which of the following should one consider while deciding whether to include them in their diet or not?

Accepted Answer

Tea and certain spices contain phytochemicals, which are beneficial compounds that can have health-promoting properties. Therefore, despite not being included in the USDA Eating Patterns, they might be considered for inclusion in one's diet for their potential health benefits.

Question 13

Identify a similarity between the USDA Eating Patterns and the Food Lists for Diabetes and Weight Management.

Accepted Answer

Both the USDA Eating Patterns and the Food Lists for Diabetes and Weight Management can be used by healthy people to guide their dietary choices and ensure balanced nutrition.

Question 14

Who among the following cannot adopt the Dietary Reference Intakes (DRI)recommendations?

Accepted Answer

The Dietary Reference Intakes (DRI) are designed for healthy individuals and populations. Robert, who has cystic fibrosis, has specific nutritional needs that may not be met by the general DRI recommendations due to his health condition.

Question 15

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 important for athletes like George who use nutrient supplements, as they indicate the maximum daily intake unlikely to cause adverse health effects. This helps in avoiding the potential risks associated with excessive nutrient intake.

Question 16

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

Accepted Answer

The percentages of the Daily Values on food labels are based on a diet of 2,000 calories a day.

Question 17

A person has eaten the following vegetables over the past week: carrots, pinto beans, corn, cauliflower, coleslaw, and potatoes. Which of the following vegetables should he eat to be sure that he has included vegetables from each of the subgroups for the week?

Accepted Answer

Broccoli belongs to the dark green vegetable subgroup, which is not represented in the list of vegetables the person has already eaten.

Question 18

Which of the following is set upon the scientific basis formed by the Estimated Average Requirements (EAR)?

Accepted Answer

The Recommended Dietary Allowances (RDA) are set based on the Estimated Average Requirements (EAR), which are the average daily nutrient intake levels estimated to meet the requirements of half the healthy individuals in a particular life stage and gender group. The RDA is calculated from the EAR by adding a safety margin to cover the needs of most (97-98%) individuals in the population.

Question 19

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

Accepted Answer

The bottom portion of the Nutrition Facts panel on food packages serves as a reminder of the Daily Values for selected nutrients, helping consumers understand how a particular food fits into their daily nutritional needs.

Question 20

Which of the following statements is true of the Daily Values?

Accepted Answer

The Daily Values are standards established in the United States that are used on food labels to give consumers a frame of reference for the nutrient content of different foods. They are not specific to age or gender, do not provide toxicity ranges, are not expressed as a percentage of total protein content, and are not necessarily a better way of determining individual nutrient goals.
