Nutrition Test 1

What DRI value is expressed as a percent of total daily calories? Acceptable Macronutrient Distribution Range (AMDR) Estimated Average Requirement (EAR) Recommended Dietary Allowance (RDA) Adequate Intake (AI

Acceptable Macronutrient Distribution Range (AMDR)

Which of the following statements regarding RDAs is true? It is important to consume the RDA for each nutrient every day. The RDA for each nutrient is essentially equal to our requirement for that nutrient. If someone typically consumes less than the RDA for a nutrient, that person will develop a deficiency. As a person's intake of a nutrient decreases relative to the RDA, his or her risk of a deficiency increases.

As a person's intake of a nutrient decreases relative to the RDA, his or her risk of a deficiency increases.

What is the consequence of nutrient intake outside the adequate and safe range? Consuming less than the adequate and safe range over time may lead to depletion of nutrient stores and malnutrition. Function is impaired due to malnutrition when an individual's intake falls below the adequate and safe range, even if short term. Adverse effects can result in consuming less than, but not more than, the adequate and safe range. Meeting or exceeding adequate and safe range of a nutrient is the best way to avoid malnutrition.

Consuming less than the adequate and safe range over time may lead to depletion of nutrient stores and malnutrition.

What Dietary Reference Intake (DRI) value is used in setting the Recommended Dietary Allowances (RDAs)? Acceptable Macronutrient Distribution Range (AMDR) Adequate Intake (AI) Estimated Energy Requirement (EER) Estimated Average Requirement (EAR)

Estimated Average Requirement (EAR)

Which statement represents an appropriate use of the Dietary Reference Intake (DRI)? Sarahi is on a low-carbohydrate diet, so she is consuming less than the AMDR for percent of calories from carbohydrate. Joe heard that vitamin C is important for the immune system, so he plans to consume supplement beverages that provide double the Upper Limit. Fatima wants to maintain adequate iron intake, so she plans her diet to meet the EAR for iron. Kiko wants to get pregnant, so she takes a supplement that, combined with her diet, meets the RDA for folic acid.

Kiko wants to get pregnant, so she takes a supplement that, combined with her diet, meets the RDA for folic acid.

After her vitamin A intake has been determined, Nora observed that it was adequate and safe, meaning her intake was greater than the _____ but did not exceed the _____. Recommended Daily Allowance; Upper Limit Estimated Average Requirement; Toxicity Level Estimated Average Requirement; Upper Limit Dietary Reference Intake; Adequate Intake

Recommended Daily Allowance; Upper Limit

Why should the Estimated Energy Requirement (EER) be used with caution? The EER is set at the low end of a group's energy needs because there is a high rate of obesity in the United States. The EER is set to meet the needs of 98% of individuals in a group, so it overestimates the energy needs of most individuals. The EER represents average energy needs, so it meets or exceeds the needs of half of the individuals in a group. The EER does not take into account physical activity levels, so it may underestimate the energy needs of active individuals.

The EER represents average energy needs, so it meets or exceeds the needs of half of the individuals in a group.

Which of the following statements is NOT true about a randomized controlled trial? The subjects do not know which treatment they are receiving. Subjects are randomly assigned to an experimental group or a control group. The experimental group receives a treatment, while the control group receives a placebo. The main purpose of this research design is to observe variables in a population.

Which of the following is TRUE of both essential and nonessential nutrients? They must be obtained from food. The body is unable to synthesize enough of them to meet its needs. Our health will improve when we consume them regularly. They are required for maintaining body functions.

They are required for maintaining body functions.

The study of nutrition does NOT typically involve which one of the following activities? determining how a nutrient is broken down and excreted from the body determining if food additives used in commercial food packaging enter foods determining how food pricing affects food purchases determining how diet affects the risk of disease

Which of the following types of studies is NOT an experiment? randomized controlled trial epidemiological study cell culture study animal study

Organic compounds that are required in small quantities belong to which class of nutrients? fats trace minerals proteins vitamins

vitamins

Which of the following nutrients do NOT supply energy? vitamins fats carbohydrates protein

When is an Adequate Intake (AI) established? when ample evidence exists to determine the needs of most healthy individuals when insufficient data exist to determine an RDA for a nutrient when a nutrient is found to be healthful but not essential for human nutrition when a nutrient, such as sodium, is often overconsumed

when insufficient data exist to determine an RDA for a nutrient
