Question 1

Which of the following is true about the use of the USDA MyPyramid?

Accepted Answer

The USDA MyPyramid emphasizes variety in food choices as the key to a healthy diet. It does not exclude any food groups, including fats, oils, and sweets, but encourages moderation and balance. While milk and meat are important sources of nutrients, the Guide also includes recommendations for plant-based sources of protein and calcium. The Guide does not apply to infants as their nutritional needs are different from those of older children and adults.

Question 2

Which of the following is not required on a nutrition label?

Accepted Answer

While nutrition labels are required to list the amount of vitamins and minerals for which there is an RDA, they are not required to list all vitamins and minerals.

Question 3

Which government agency is responsible for regulating most U.S. food labeling?

Accepted Answer

The Food and Drug Administration (FDA) is responsible for regulating most U.S. food labeling, ensuring that food products are accurately labeled with ingredients, nutrition information, and health claims. The U.S. Department of Agriculture (USDA) primarily regulates meat, poultry, and egg products, while the Bureau of Alcohol, Tobacco, and Firearms (ATF) regulates labeling of alcoholic beverages. The Center for Science in the Public Interest (CSPI) is a non-profit organization that advocates for improved food labeling and other nutrition policies, but does not have regulatory authority.

Question 4

The number of servings to consume from each MyPyramid food group depends on a person's

Accepted Answer

The number of servings to consume from each MyPyramid food group depends on a person's age, gender, and physical activity level. This information is used to create personalized dietary recommendations that take into account an individual's nutritional needs and goals. Height, weight, and waist circumference are factors that are considered in assessing overall health, but they are not directly used to determine serving sizes from each food group. Taste preferences and frame size are not relevant factors in determining serving sizes from each food group.

Question 5

Margaret, an elderly woman, needs to limit her kcalorie intake without sacrificing needed nutrients. Keeping in mind MyPyramid, which of the following could she do?

Accepted Answer

Margaret should carefully select foods that are rich in nutrients but low in kcalories to meet her nutritional needs while limiting her kcalorie intake. Eliminating a whole food group or macronutrient (such as carbohydrates or dairy foods) is not necessary and could lead to nutrient deficiencies. Counting kcalories can be a useful tool, but it is important to also consider MyPyramid recommendations and choose a variety of nutrient-dense foods from all food groups.

Question 6

Missy visits a doctor because she feels tired most of the time, is easily distracted, and feels chilled. As part of her examination, Missy has blood drawn to be tested for concentrations of nutrients and their by-products. This part of the examination is the

Accepted Answer

A biochemical evaluation involves testing body fluids, such as blood or urine, for concentrations of nutrients, hormones, and other by-products that can indicate a person's nutritional status and health conditions. This type of evaluation can help identify specific nutrient deficiencies or imbalances that may be causing Missy's symptoms. The other options are not specific to testing for nutrients and their by-products.

Question 7

Which of the following is not a limitation of nutritional assessments?

Accepted Answer

This choice is the only one that suggests a limitation that is not a common drawback of nutritional assessments. Nutritional assessments can be time-consuming and costly, but they do provide valuable information that can guide patient care. The other choices describe limitations that are well-established in the field of nutrition assessment.

Question 8

Nutrient density can be defined as the amount of

Accepted Answer

Nutrient density is a measure of how many essential nutrients a food contains per calorie. Choice A defines nutrient density as the amount of a particular nutrient in a serving of food divided by the number of kcalories in that serving, which is a common way to measure the nutrient density of a food. Choices B, C, and D do not accurately define nutrient density.

Question 9

Which of the following is not a wise application of the USDA MyPyramid?

Accepted Answer

Eliminating foods from the oils group entirely is not recommended as some oils can be beneficial in moderation for heart health. It is important to choose oils that are high in healthy fats, such as olive or canola oil, rather than eliminating them completely.

Question 10

Mrs. Mitchell was hospitalized after being found unconscious in her home. A dietitian conducted a nutritional assessment noting the general appearance of Mrs. Mitchell's skin, eyes, and tongue. Which part of the assessment is this?

Accepted Answer

The assessment conducted by the dietitian noting the appearance of Mrs. Mitchell's skin, eyes, and tongue is a part of the clinical examination, which helps to identify any physical signs and symptoms related to nutritional deficiencies or excesses.

Question 11

The Dietary Guidelines were issued in response to

Accepted Answer

The Dietary Guidelines were issued in response to concerns regarding disease patterns in the United States, particularly the prevalence of chronic diseases such as heart disease, diabetes, and obesity. The guidelines aim to provide recommendations for healthy eating patterns that can help prevent these diseases and promote overall health and well-being.

Question 12

When looking at the ingredient label of a bottled spaghetti sauce, you see that olive oil is the second ingredient. This means that olive oil is

Accepted Answer

The listing of ingredients on a label must follow FDA regulations, which require components to be listed in descending order of predominance by weight. Therefore, if olive oil is the second ingredient, it represents the second largest amount of ingredients by weight.

Question 13

Jeff, a world-class triathlete, visits a dietitian to obtain sports nutrition advice. During his visit, Jeff is asked to recall what he ate for the past 24 hours. Which part of a nutritional assessment is this?

Accepted Answer

Recalling what one ate for the past 24 hours is part of a diet history, which is an important component of a nutritional assessment. A biochemical evaluation involves analyzing blood or urine samples, a clinical examination involves physical assessments, and menu planning involves creating a meal plan based on individualized nutritional needs.

Question 14

The acronym DRI stands for

Accepted Answer

DRI stands for Dietary Reference Intake, which is a set of nutrient reference values that are used to assess and plan diets for healthy individuals. These values are updated and maintained by the Food and Nutrition Board of the National Academies of Sciences, Engineering, and Medicine.

Question 15

Kate consumes 1,900 kcalories each day. She requires 1,750 kcalories to meet daily energy needs. Over time, Kate's kcalorie consumption could lead to

Accepted Answer

Kate's kcalorie consumption exceeds her daily energy needs, which could lead to overnutrition and potentially weight gain or other health issues related to excessive intake of certain nutrients.

Question 16

According to the Dietary Guidelines the food groups to encourage are

Accepted Answer

The Dietary Guidelines recommend consuming a variety of fruits and vegetables, whole grains, and low-fat dairy products. These food groups provide essential nutrients for optimal health and should be emphasized in a healthy diet. Milk, meat, and beans are also important sources of nutrients but should be consumed in moderation as part of a well-balanced diet. Grains, beans, and oils are also important but should be consumed in moderation and chosen wisely, as they can be high in calories and fat. Fruit juice, while a source of vitamins and minerals, should be consumed in moderation due to its high sugar content.

Question 17

A nutrition label must be present on the product if

Accepted Answer

The answer of A nutrition label must be present on...

Question 18

The Dietary Guidelines for Americans recommends which of the following?

Accepted Answer

The Dietary Guidelines for Americans recommend being physically active each day as an important aspect of maintaining a healthy lifestyle. Option A and D are also recommended, but not as broadly applicable as Option C. Option B is not recommended as excessive alcohol consumption can have negative health effects.

Question 19

Which of the following statements is consistent with the Dietary Guidelines for Americans?

Accepted Answer

The Dietary Guidelines for Americans recommend balancing the food you eat with physical activity, meaning you should consume a variety of nutrient-dense foods in appropriate portion sizes while also engaging in regular physical activity. A is incorrect because the current guidelines focus more on reducing saturated and trans fats rather than all fats; C is incorrect because while animal products can be part of a healthy diet, the guidelines emphasize the importance of consuming a variety of food sources, including plant-based options; D is incorrect because the guidelines recommend limiting saturated fats as they have been linked to increased risk of heart disease.

Question 20

One cup of apple juice has 111 kcalories and 1.4 mg of vitamin C. The same serving size of orange juice has 112 kcalories and 124 mg of vitamin C. Which of the following is true regarding their nutrient density?

Accepted Answer

Orange juice has a higher amount of vitamin C per serving size, making it more nutrient dense in terms of vitamin C compared to apple juice. However, if an individual is watching their overall kcalorie intake, they may choose to consume a smaller serving size of orange juice or opt for a lower kcalorie alternative for their vitamin C needs.
