Accepted Answer

The leading causes of death among Americans are actually heart disease and cancer. Accidents and diabetes are among the top 10 causes of death, but they do not hold the top two spots.

Question 5

Reducing the proportion of adults who are obese and eliminating very low food security are Healthy People 2020 nutrition objectives for the nation.

Accepted Answer

This statement is true. The Healthy People 2020 objectives include decreasing the proportion of adults who are obese and eliminating very low food security as targets for improving nutrition and overall health in the United States.

Question 6

The American Heart Association concludes that future gains in heart health among Americans will stem primarily from _____.​

Accepted Answer

The American Heart Association concludes that future gains in heart health among Americans will stem primarily from improved dietary intakes. This includes reducing sodium and saturated fat intake and increasing fruits and vegetables consumption.

Question 7

Which type of diabetes is the most common?​

Accepted Answer

Type 2 diabetes is the most common type, accounting for more than 90% of all diabetes cases.

Question 8

Vitamins A and D function as antioxidants.​

Accepted Answer

While vitamin A may have some antioxidant properties, vitamin D is not known to function as an antioxidant.

Question 9

Chronic diseases are on the rise in countries adopting the Western diet.​

Accepted Answer

Numerous studies have shown that the adoption of a Western diet high in processed foods, saturated fats, and refined sugars is associated with an increase in chronic diseases such as obesity, type 2 diabetes, cardiovascular disease, and certain cancers.

Question 10

Beginning in 2011,food guidance materials became labeled "MyPyramid."​

Accepted Answer

Beginning in 2011, food guidance materials were labeled "MyPlate," not "MyPyramid." MyPlate replaced MyPyramid as the government's primary food group symbol.

Question 11

Low intake of fruits and vegetables and regular consumption of processed meat is linked to cancer.​

Accepted Answer

Numerous studies have shown a correlation between a low intake of fruits and vegetables, and regular consumption of processed meat and an increased risk of various types of cancer, including colon, stomach, and lung cancers. Consuming a diet rich in fruits and vegetables and limiting consumption of processed and red meats is recommended for cancer prevention.

Question 12

The bodies of modern humans adapted to exist on a diet of wild game,fish,fruits,nuts,seeds,roots,vegetables,and grubs.​

Accepted Answer

This statement is true. The human body evolved over thousands of years to be able to efficiently digest and derive nutrients from a diet that primarily consisted of wild game, fish, fruits, nuts, seeds, roots, vegetables, and grubs. This type of diet is often referred to as a paleo or ancestral diet.

Question 13

​Some diseases are promoted by interactions between nutrients and genes.

Accepted Answer

Nutrients can interact with genes to affect gene expression, which can contribute to the development of certain diseases. For example, individuals with certain genetic variations may be more susceptible to developing type 2 diabetes when consuming a high-sugar diet. Similarly, certain genetic variations have been linked to a higher risk of cardiovascular disease when consuming a diet high in saturated fat.

Question 14

Free radicals are chemical substances that are missing electrons.​

Accepted Answer

Free radicals are indeed chemical substances that are missing one or more electrons, making them unstable and highly reactive. They can cause damage to cells and tissues, and have been linked to various health issues, including aging, cancer, and heart disease.

Question 15

A dietary risk factor linked to Alzheimer's disease is _____.​

Accepted Answer

Regular intake of high animal-fat products has been linked to an increased risk of Alzheimer's disease. This is because high intake of saturated and trans fats can lead to inflammation and damage in the brain, contributing to the development and progression of Alzheimer's disease. Therefore, reducing intake of high animal-fat products may help lower the risk of developing Alzheimer's disease.

Question 16

Regular consumption of processed meats and low vegetable and fruit intake is associated with the development of _____.​

Accepted Answer

Processed meats and low intake of vegetables and fruits have been linked to an increased risk of cancer due to the presence of carcinogens and lack of protective nutrients.

Question 17

The National Health and Nutrition Examination Survey assesses dietary intake,health,and nutritional status in a sample of adults and children in the United States on a continual basis.​

Accepted Answer

The National Health and Nutrition Examination Survey (NHANES) is a program that assesses dietary intake, health, and nutritional status of a sample of adults and children in the United States on an ongoing basis. Therefore, the statement is true.

Question 18

​Americans have the highest life expectancy in the world.

Accepted Answer

Americans do not have the highest life expectancy in the world. According to World Bank data from 2018, countries like Japan, Switzerland, and Singapore have a higher life expectancy than the United States.

Question 19

Chronic diseases are an inevitable consequence of Westernization.​

Accepted Answer

Chronic diseases are influenced by a variety of factors including genetics, environment, lifestyle choices, and healthcare access, not solely Westernization. Many non-Western countries also experience high rates of chronic diseases due to these factors.

Question 20

Genetic traits exert the strongest overall influence on health and longevity.​

Accepted Answer

While genetic traits do play a significant role in determining an individual's health and longevity, environmental factors, lifestyle choices, and access to healthcare also have substantial impacts on these outcomes.
