Question 2

The standard that represents the average nutrient intake estimated to meet the daily requirements of 50% of healthy individuals is called the

Accepted Answer

The Estimated Average Requirement (EAR) represents the average nutrient intake estimated to meet the daily requirements of 50% of healthy individuals.

Question 3

Gram for gram,which nutrient(s)provide(s)the least energy?

Accepted Answer

Both protein and carbohydrates provide 4 calories per gram, which is less than lipids (9 calories per gram) and alcohol (7 calories per gram).

Question 4

How many water-soluble and fat-soluble vitamins do we know of?

Accepted Answer

There are 10 water-soluble vitamins and 4 fat-soluble vitamins.

Question 5

The standard that represents the average nutrient intake estimated to meet the daily requirements of nearly 98% of healthy individuals is called the

Accepted Answer

Recommended Dietary Allowance (RDA) represents the average nutrient intake that meets the daily requirements of nearly 98% of healthy individuals. It is calculated based on age, gender, and life stage and is designed to prevent nutrient deficiencies.

Question 6

Minerals are classified into "major" and "trace" minerals.Which of the following lists only contains major minerals?

Accepted Answer

The list D contains only major minerals: potassium, sodium, magnesium, and calcium. Major minerals are required in larger amounts by the body, whereas trace minerals are required in smaller amounts.

Question 7

Linda takes calcium and vitamin D supplements but is worried about increasing her risk for kidney stones.Which of the following standards will provide Linda with the information necessary to determine the maximum amount of nutrients that would be safe for her to consume without the risk of side effects?

Accepted Answer

The Tolerable Upper Intake Level (UL) is the standard that provides information on the maximum amount of nutrients a person can consume safely without the risk of adverse effects. In Linda's case, she wants to know the maximum amount of calcium and vitamin D she can consume without increasing her risk of kidney stones, so the UL is the appropriate standard to use. The other options, such as Recommended Dietary Allowance (RDA) and Adequate Intake (AI), provide information on the minimum amount of nutrients needed for optimal health, while Acceptable Macronutrient Distribution Range (AMDR) deals with the proportions of different types of macronutrients (such as protein, carbohydrates, and fat) in the diet. The Estimated Average Requirement (EAR) is a standard used to assess the adequacy of nutrient intake in populations, but it is not typically used for individual recommendations.

Question 8

According to the Acceptable Macronutrient Distribution Range,20% to 35% of the total caloric intake should come from fat.If Marcus is on a 3,500 kilocalorie diet,how many kilocalories should he obtain from dietary fat?

Accepted Answer

The range for fat intake on a 3,500 kcal diet is 20% to 35%. Calculating 20% of 3,500 gives 700 kcal, and 35% gives 1,225 kcal. Therefore, Marcus should obtain between 700 and 1,225 kilocalories from dietary fat.

Question 9

Sarah is making a pound cake for the bake sale.Of the 2,400 total kilocalories for the entire cake,30% comes from fat.How many grams of fat are there in the cake?

Accepted Answer

To find the number of grams of fat in the cake, we need to first find the total number of kilocalories from fat. We can do this by multiplying the total number of kilocalories (2,400) by the percentage of calories that come from fat (30% or 0.3):

2,400 x 0.3 = 720 kilocalories from fat

Next, we need to convert kilocalories to grams, since the nutrition labels on food typically list fat in grams. One gram of fat has 9 kilocalories, so we can divide 720 by 9 to get the number of grams of fat:

720/9 = 80 grams

Therefore, there are 80 grams of fat in the pound cake. The correct answer is C, 80 grams.

Question 10

Which of the following statements is NOT true about epidemiological studies?

Accepted Answer

Epidemiological studies do not randomly assign subjects to experimental and control groups. Instead, they observe and collect data on variables in a population without any intervention.

Question 11

Based on the Acceptable Macronutrient Distribution Range,what is the recommendation for carbohydrate intake?

Accepted Answer

The Acceptable Macronutrient Distribution Range recommends that carbohydrates should make up 45%-65% of one's daily calorie intake. This range provides enough nutrients for energy and supports other bodily functions while also allowing room for a balance of fats and proteins in the diet.

Question 12

Which of the following is a water-soluble vitamin?

Accepted Answer

Water-soluble vitamins are those that can dissolve in water and are easily excreted from the body. Vitamin C is a water-soluble vitamin, while vitamins A, D, E, and K are fat-soluble vitamins.

Question 13

The standard that provides recommendations for healthy ranges of energy-yielding macronutrients is termed the

Accepted Answer

Acceptable Macronutrient Distribution Range (AMDR) provides recommendations for healthy ranges of energy-yielding macronutrients including carbohydrates, fats, and proteins. The AMDR is expressed as a percentage of total daily caloric intake and is designed to promote optimal health while reducing the risk of chronic diseases.

Question 14

What is the standard unit used to measure food energy?

Accepted Answer

Kilocalories (kcal) are the standard unit used to measure food energy. It is the amount of energy required to raise the temperature of 1 kilogram of water by 1 degree Celsius. This unit is commonly used on nutrition labels to indicate the amount of energy provided by a particular food.

Question 15

David is a football player consuming a high-calorie diet.His daily caloric intake is set at 4,500 kilocalories with the macronutrient distribution as follows: 45% carbohydrates,18% fat,and the rest from protein.How many grams of protein is David's diet providing? (Round your answer to the nearest whole number)

Accepted Answer

The answer of David is a football player consuming a...

Question 16

What is the correct sequence of steps in following the scientific method to conduct research?

Accepted Answer

The scientific method starts with making observations and then proposing a hypothesis based on those observations. The hypothesis is then tested by conducting an experiment. Finally, a theory can be developed based on the results of the experiment. So, the correct sequence of steps in following the scientific method to conduct research is to make observations, propose hypothesis, conduct experiment, and develop a theory.

Question 17

Which of the following diseases is NOT related to diet?

Accepted Answer

Pneumonia is an infection of the lungs and is not related to diet. The other options are all related to diet in some way.

Question 18

Micronutrients are those that are required in small quantities.Which of the following is NOT a micronutrient?

Accepted Answer

Fiber is not a micronutrient, it is a type of carbohydrate that is important for digestive health, but is not required in small quantities like micronutrients.

Question 19

Based on the Acceptable Macronutrient Distribution Range,what is the recommendation for protein intake?

Accepted Answer

The Acceptable Macronutrient Distribution Range recommends that protein intake should be between 10% and 35% of total daily calorie intake. This range is based on the needs of the average healthy adult and provides enough protein to support overall health and wellness, as well as physical activity and exercise. This range may be adjusted for individuals with specific health concerns or dietary needs, such as athletes or individuals with kidney disease, under the guidance of a healthcare professional. Option B falls within this range and is therefore the best choice.
