Question 1

If a computerized dietary analysis system has a database with a large amount of incomplete data or many blanks in the database, the system's output may understate a client's actual nutrient intake. In such cases, reported low nutrient intakes represent a __________ deficiency, not necessarily an actual deficiency in the client's diet.

Accepted Answer

Database

Question 2

The on-line dietary assessment tool developed by the USDA's Center for Nutrition Policy and Promotion is Choose My Plate __________.

Accepted Answer

SuperTracker

Question 3

The system developed by W. O. Atwater to calculate the energy contributed by protein, fat, and carbohydrates in foods is known as the __________ system.

Accepted Answer

Atwater

Question 4

It is always preferable to have a diet analysis system with a database having a large number of foods and a large number of nutrients and food components.

Accepted Answer

A larger database isn't always preferable because it can include many irrelevant or rarely consumed foods, making it harder for users to find what they're looking for. Additionally, maintaining accuracy and up-to-date information on a vast number of nutrients and food components can be challenging, potentially leading to errors or outdated data. A well-curated, relevant, and accurate database is often more useful than a larger, less manageable one.

Question 5

Which one of the following is the nutrient database used to analyze food intake information collected by What We Eat in America, NHANES?
A) National Nutrient Database
B) Nutrient Database for Standard Reference
C) Food and Nutrient Database for Dietary Studies

Accepted Answer

The Food and Nutrient Database for Dietary Studies (FNDDS) is the nutrient database used by What We Eat in America, NHANES to analyze food intake information collected. The National Nutrient Database and Nutrient Database for Standard Reference are other nutrient databases maintained by the USDA, but they are not used for this specific purpose.

Question 6

When nutrient data for prepared or cooked products are unavailable or incomplete, nutrient values are __________ from comparable raw items or by recipe.

Accepted Answer

The answer of When nutrient data for prepared or cooked...

Question 7

The USDA began publishing food composition data in
A) the 1890s
B) the 1920s
C) the 1940s
D) the 1960s

Accepted Answer

The USDA started publishing food composition data in the 1890s, marking the beginning of a comprehensive effort to provide information on the nutritional content of foods.

Question 8

Every food item in a nutrient database may not contain complete information for every vitamin, mineral, or food component. These blanks in the database are referred to as __________ data.

Accepted Answer

The answer of Every food item in a nutrient database...

Question 9

Food composition data from the laboratory analysis of one or more samples of the food are known as __________ data.

Accepted Answer

The answer of Food composition data from the laboratory analysis...

Question 10

Although the USDA Nutrient Database for Standard Reference provides values on more than 140 nutrients and food components for more than 7900 foods, relatively few recipes and name brand foods are found in the database.

Accepted Answer

The statement accurately reflects the limitation of the USDA Nutrient Database for Standard Reference. While it provides detailed nutrient information for a wide variety of raw and unprocessed foods, it does not include as much information on specific branded products or complex recipe dishes.

Question 11

Which one of the following is the most important consideration to make when selecting a computerized diet analysis system?
A) how easy the program is to operate
B) the quality of its nutrient database
C) the system's output characteristics

Accepted Answer

The quality of the nutrient database is the most important consideration when selecting a computerized diet analysis system as it directly impacts the accuracy of the analysis. Easy operation and system output characteristics are important but secondary considerations.

Question 12

Choosing a similar food from a computer database when the specific food is not in the database is known as
A) derivation
B) imputing
C) retention
D) substitution

Accepted Answer

The answer of Choosing a similar food from a computer...

Question 13

An effort on the part of the United Nations to improve data on the nutrient composition of foods from all parts of the world is known by the acronym
A) AOAC
B) BHNRC
C) FSIS
D) INFOODS

Accepted Answer

INFOODS (International Network of Food Data Systems) is the United Nations effort to improve data on nutrient composition of foods from all parts of the world. AOAC (Association of Official Analytical Chemists) is a non-profit scientific organization that provides an independent forum for the development and validation of analytical methods. BHNRC (Beltsville Human Nutrition Research Center) is a research center focused on improving public health through research in nutrition and food safety. FSIS (Food Safety and Inspection Service) is a branch of the United States Department of Agriculture responsible for ensuring the safety and proper labeling of meat, poultry, and egg products.

Question 14

The identification number for each food item in the USDA Nutrient Database is known as
A) the derivation code
B) the food group code
C) the NDB number
D) the source code

Accepted Answer

The identification number for each food item in the USDA Nutrient Database is known as the NDB number.

Question 15

Which one of the following serves as the core for most commercial and many international nutrient databases?
A) National Nutrient Database
B) Nutrient Database for Standard Reference
C) Food and Nutrient Database for Dietary Studies

Accepted Answer

The Nutrient Database for Standard Reference serves as the core for most commercial and many international nutrient databases. It is developed and maintained by the United States Department of Agriculture (USDA) and contains nutrient data for over 8,000 foods. The National Nutrient Database and the Food and Nutrient Database for Dietary Studies are also maintained by the USDA but are not as widely used as the Nutrient Database for Standard Reference.

Question 16

Nutrient values in a database that are taken from another form of the same food or similar food are imputed values.

Accepted Answer

Imputed values are nutrient values estimated or assigned to a food item based on another form or a similar food's nutrient values in a database.
