Accepted Answer

Heart disease, stroke, and diabetes are all considered to be diet-related causes of death. While cancer can have some links to diet, it is generally not considered to be directly caused by dietary factors. The other answer choices do not include a combination of three diet-related causes within the 10 leading causes of death.

Question 7

Compared with the Estimated Average Requirement, the Recommended Dietary Allowances for nutrients are set at _____ level.

Accepted Answer

The answer of Compared with the Estimated Average Requirement, the...

Question 8

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 is the standard that provides information on the maximum amount of nutrients that can be consumed without the risk of adverse effects. This standard is used to set safe upper limits of nutrient intake and is appropriate for Linda's concern about the risk of kidney stones associated with excess calcium intake.

Question 9

The Acceptable Macronutrient Distribution Range recommends that carbohydrates contribute _____ of daily calories.

Accepted Answer

The Acceptable Macronutrient Distribution Range (AMDR) recommends that carbohydrates contribute 45%-65% of daily calories. This range provides enough carbohydrates to meet the body's energy needs while also allowing for appropriate intake of protein and fat. A lower intake of carbohydrates can lead to inadequate energy and decreased physical and mental performance, while an excessively high intake of carbohydrates can contribute to weight gain and other health issues.

Question 10

According to findings of the National Health and Nutrition Examination Survey (NHANES):

Accepted Answer

All of these findings are correct according to the NHANES.

Question 11

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

Accepted Answer

To find the grams of fat in the cake, we need to convert the total kilocalories to calories and then multiply by the percentage of calories that come from fat.

1 kilocalorie = 1,000 calories

So, the total calories in the cake = 2,400 x 1,000 = 2,400,000 calories

30% of the total calories come from fat, so:

Calories from fat = 2,400,000 x 0.3 = 720,000 calories

Each gram of fat contains 9 calories, so:

Grams of fat = 720,000 / 9 = 80,000 / 1,000 = 80 grams

Therefore, the answer is (C) 80 grams.

Question 12

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) is the standard that represents the average nutrient intake estimated to meet the daily requirements of nearly 98% of healthy individuals. It takes into account factors such as age, gender, and life stage and is based on scientific evidence of nutrient intake and health outcomes. The other options, such as Adequate Intake (AI) and Acceptable Macronutrient Distribution Range (AMDR), are also important guidelines for nutrient intake, but they do not represent the same level of certainty as the RDA. The Estimated Average Requirement (EAR) is a separate guideline that represents the nutrient intake level that is estimated to meet the requirements of half of healthy individuals, while the Estimated Energy Requirement (EER) represents the average daily energy intake that is predicted to maintain energy balance in healthy adults.

Question 13

What is the primary form of fat in our bodies?

Accepted Answer

Triglycerides are the primary form of fat in our bodies. They are composed of three fatty acids attached to a glycerol molecule and are stored in adipose tissue for energy. Cholesterol, phospholipids, and lipoproteins are also types of fats, but they are not the primary form stored in our bodies. Omega-3 fatty acids are essential fatty acids that must be obtained from the diet and are important for many bodily functions, but they are not the primary form of fat in our bodies.

Question 14

The risk of adverse effects associated with intake of a nutrient:

Accepted Answer

The risk of adverse effects associated with nutrient intake increases both at levels below the Recommended Dietary Allowance (RDA), due to potential nutrient deficiencies, and above the Tolerable Upper Intake Level (UL), due to potential toxicity or adverse effects.

Question 15

A nutrient that cannot be made by the body in sufficient quantities and that must be obtained from food is a/an:

Accepted Answer

An essential nutrient is a nutrient that the body cannot produce in sufficient amounts and must be obtained from the diet. Organic and inorganic nutrients refer to the chemical composition of the nutrient, while phytochemicals and functional nutrients refer to specific properties or functions of certain nutrients.

Question 16

David is a football player consuming a high-calorie diet. His daily caloric intake is set at 4,500 kilocalories with the following macronutrient distribution: 45% carbohydrate, 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 17

Which of the following is NOT considered an essential nutrient?

Accepted Answer

Phytochemicals are beneficial compounds found in plants, but they are not considered essential nutrients because the body can still function without them. Essential nutrients are those that the body cannot produce on its own and must be obtained through food or supplements.

Question 18

Which of the following is the only animal product with significant carbohydrate?

Accepted Answer

Milk is the only animal product that contains significant carbohydrates, specifically lactose. The other choices, such as chicken, beef, butter, and eggs, contain minimal to no carbohydrates.

Question 19

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

Accepted Answer

Major minerals are those that are required in larger amounts by the body, and D contains the major minerals of potassium, sodium, magnesium, and calcium.

Question 20

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

Accepted Answer

The correct sequence of the scientific method is to first make observations to identify a pattern or problem. Based on those observations, a hypothesis can be proposed as a possible explanation. Then, an experiment can be designed and conducted to test the hypothesis. Finally, the results of the experiment can be used to develop a theory that explains the phenomenon being studied. Option B follows this correct sequence.
