Question 1

Recommendations for vitamins and minerals, carbohydrates, fibre, lipids, proteins, and energy have been published by the Dietary Reference Intakes (DRI) committee.

Accepted Answer

The Dietary Reference Intakes (DRI) committee publishes recommendations for vitamins and minerals, carbohydrates, fiber, lipids, proteins, and energy to guide dietary planning and to ensure nutritional adequacy for individuals and populations.

Question 2

Which term refers to the compound contained in flaxseed that is converted into biologically active phytoestrogens by bacteria in the human intestine?

Accepted Answer

Lignans in flaxseed are converted by intestinal bacteria into enterolignans, which are biologically active phytoestrogens. These compounds can mimic or modulate the body's own estrogens, potentially impacting various health aspects positively.

Question 3

According to the Canadian Physical Activity Guidelines for Adults-18-64 years, how much exercise is recommended for adults to maintain a healthy body?

Accepted Answer

The Canadian Physical Activity Guidelines for Adults aged 18-64 recommend at least 150 minutes of moderate- to vigorous-intensity aerobic physical activity per week, in bouts of 10 minutes or more.

Question 4

The Reference Daily Values on food labels for cholesterol, total fat, and sodium suggests an intake goal to strive to reach.

Accepted Answer

The Reference Daily Values on food labels for cholesterol, total fat, and sodium are intended to guide consumers on the maximum amount they should consume in a day, not a goal to strive to reach.

Question 5

Using the concept of portion control, which of the following common objects is an acceptable way to identify a medium-sized piece of fruit?

Accepted Answer

A regular 60-watt light bulb is often used as a visual guide for the size of a medium piece of fruit, such as an apple or an orange.

Question 6

On average, consuming 100 percent of the Dietary Reference Intakes (DRI) for every nutrient ensures adequate intake over time.

Accepted Answer

The Dietary Reference Intakes (DRI) are designed to cover the needs of nearly all (97-98%) healthy individuals in a specific age and gender group when consumed on average over time, ensuring adequate intake of essential nutrients.

Question 7

Which statement best describes Estimated Energy Requirements (EER)?

Accepted Answer

Estimated Energy Requirements (EER) are calculated values that predict the amount of energy (calories) an individual needs to consume to maintain their current body weight, taking into account factors like age, sex, weight, height, and level of physical activity. This is aimed at promoting a balance between energy intake and energy expenditure for maintaining a healthy body weight.

Question 8

Which of the following foods is a source of lycopene?

Accepted Answer

Lycopene is a phytonutrient found in red and pink fruits, with watermelon being a significant source.

Question 9

Which standard establishes population-wide average requirements used by nutrition policymakers?

Accepted Answer

Estimated Average Requirements (EAR) are designed to assess the adequacy of nutrient intakes in populations and are used by nutrition policymakers for this purpose.

Question 10

What does the absence of a tolerable upper intake level (UL) for a specific nutrient indicate?

Accepted Answer

The absence of a tolerable upper intake level (UL) for a specific nutrient indicates that there is insufficient data to establish a value for the nutrient. This means that scientists and nutrition experts do not have enough evidence to determine a maximum daily intake level beyond which the nutrient could potentially cause adverse health effects.

Question 11

As a nation, Canadians are eating too few servings of the protein food group.

Accepted Answer

According to Canada's Food Guide, Canadians are encouraged to consume a variety of protein foods, including plant-based options, but there is no widespread evidence suggesting that Canadians are eating too few servings of the protein food group overall.

Question 12

According to the comprehensive summary of Canada's Food Guide tools and resources, which of the following processed foods may be considered part of a healthy eating pattern?

Accepted Answer

Frozen vegetables are considered part of a healthy eating pattern as they can retain most of their nutrients and are a convenient option to include vegetables in meals.

Question 13

A diet-related health claim on a food label is acceptable for which of the following health conditions?

Accepted Answer

Diet-related health claims on food labels are acceptable for conditions like high blood pressure, where dietary choices (such as low sodium intake) can have a direct impact on managing the condition. Conditions like diabetes, food allergies, and celiac disease require more specific dietary management that goes beyond simple health claims.

Question 14

The primary difference between recommendations for nutrient intakes and values set for energy intake is that the value for energy intake is generous.

Accepted Answer

The primary difference is that recommendations for nutrient intakes are aimed at preventing deficiencies and promoting optimal health, while values set for energy intake are tailored to match an individual's energy expenditure to maintain body weight. Energy intake recommendations are not necessarily generous but are calculated to balance energy expenditure.

Question 15

Which statement best describes the recommended dietary allowances (RDA)?

Accepted Answer

RDAs are established as average intake levels sufficient to meet the nutrient requirements of nearly all (97-98%) healthy individuals in a particular life stage and gender group. They are not updated annually, nor are they minimum requirements or specifically based on chronic disease risk.

Question 16

What is the name for the type of fat in butter, milk, and other dairy products that has shown some healthful biological activity in animal studies?

Accepted Answer

Conjugated linoleic acid (CLA) is the type of fat found in butter, milk, and other dairy products that has demonstrated potential health benefits in animal studies. It is known for its possible anti-carcinogenic and anti-diabetes properties, among other health benefits.

Question 17

According to Canada's Food Guide, which of the following food items should fill half of your plate at meals?

Accepted Answer

According to Canada's Food Guide, half of your plate should be filled with fruits and vegetables, which includes options like mixed peas and carrots.

Question 18

You are speaking to a group of consumers about ways to use food labels to choose healthy foods in the grocery store. Which point would you emphasize during your presentation?

Accepted Answer

Understanding the descriptor terms used on food labels is crucial for consumers to make informed choices about the healthiness of food products. These terms can indicate if a product is low in a particular nutrient, such as fat or sugar, or if it is high in beneficial nutrients like fiber.

Question 19

Which statement best describes the dietary reference intakes (DRI)?

Accepted Answer

Dietary Reference Intakes (DRI) are designed for healthy individuals, providing guidance on nutrient intake levels to prevent deficiencies and reduce the risk of chronic diseases.

Question 20

The absence of a tolerable upper intake level (UL) for a nutrient implies that it is safe to consume in any amount.

Accepted Answer

The absence of a UL does not imply unlimited safety; it may indicate insufficient data to establish a safe upper limit.
