Question 1

Basal metabolic rate generally increases with age.

Accepted Answer

Basal metabolic rate actually decreases with age because muscle mass decreases and body fat increases, which leads to a decrease in the body's energy needs.

Question 2

Diet plans generated at ChooseMyPlate.gov are based on age,sex,and weight but not physical activity level.

Accepted Answer

This statement is incorrect. The diet plans generated at ChooseMyPlate.gov are based on age, sex, weight, and physical activity level.

Question 3

Children of long-lived parents tend to live somewhat longer as a group than children whose parents had shorter life spans.This relationship strengthens as parents live beyond the age of _____.

Accepted Answer

The relationship between the longevity of parents and their children strengthens as the parents live beyond the age of 80. This suggests that genetic factors associated with longevity become more influential as parents reach older ages.

Question 4

Among adults and the elderly in the United States,average dietary intake of vitamins A,D,and E are below the recommended intake levels.

Accepted Answer

According to the National Health and Nutrition Examination Survey (NHANES), the average dietary intake of vitamins A, D, and E are below the recommended intake levels among adults and the elderly in the United States.

Question 5

Above average intake of vegetables,fruits,and _____ may delay the development or help prevent a number of types of cancer,heart disease,hypertension,and cataracts.

Accepted Answer

The question asks for what may delay the development or help prevent a number of types of cancer, heart disease, hypertension, and cataracts. Out of the given options, whole-grain foods would be the best choice to fit that criteria as they contain fiber, vitamins, and minerals that are beneficial for overall health and disease prevention. Fruits and vegetables are also mentioned in the question and they are a good source of many of the same nutrients as whole-grain foods. Dairy products, meats, seafood, and alcohol are not specifically mentioned as being beneficial for disease prevention in the question.

Question 6

The RDA for _____ is higher for adults over 70 compared to adults 19-50 years old.

Accepted Answer

The RDA for calcium is higher for adults over 70 compared to adults 19-50 years old, as bone mass decreases with age, making calcium intake important for maintaining bone health. The RDA for folate, vitamin C, vitamin A, and potassium do not differ based on age.

Question 7

Diseases such as Alzheimer's disease can affect the senses of taste and smell.

Accepted Answer

Alzheimer's disease can cause a decrease in the sense of taste and smell. This can impact a person's appetite and quality of life.

Question 8

Adequate _____ and engaging in regular physical activity during the adult years may help maintain muscle mass and strength.

Accepted Answer

Protein is necessary for building and repairing muscle tissue, and adequate protein intake, along with regular physical activity, can help maintain muscle mass and strength during adulthood. While water, potassium, fiber, and polyunsaturated fat are all important for overall health, they do not specifically target muscle mass and strength maintenance.

Question 9

Reduction in calorie need with age increases the importance of energy-dense diets.

Accepted Answer

As people age, their calorie needs generally decrease, but the importance of nutrient-dense diets increases to ensure they get the necessary vitamins and minerals without excess calories.

Question 10

Which group has the highest life expectancy in the United States?​

Accepted Answer

Hispanic American women generally have the highest life expectancy in the United States, often attributed to various socio-cultural factors, including strong community and family support networks.

Question 11

Some species of animals fed low-calorie diets have increased life expectancies.

Accepted Answer

Studies on animals like mice, rats, and worms have shown that lower calorie diets can extend their lifespans. However, it's important to note that these findings may not necessarily apply to all species, including humans, and further research is still needed.

Question 12

Which group has the lowest life expectancy in the United States??​

Accepted Answer

African American women have the lowest life expectancy in the United States due to a combination of factors, including socioeconomic disparities, access to healthcare, and chronic health conditions.

Question 13

Isolation and loneliness do not appear to contribute to poor diets in older adults.

Accepted Answer

Studies have shown that isolation and loneliness are associated with poor diets in older adults. The lack of social support and companionship may lead to decreased motivation to cook and eat healthy meals. Additionally, social isolation may limit access to fresh and nutritious food options.

Question 14

Optimism and an active social life appear to enhance well-being and longevity.

Accepted Answer

Research studies have consistently shown that individuals who have a positive outlook on life and an active social life tend to live longer and have better overall well-being compared to those who are more pessimistic and socially isolated. Optimism can help reduce stress, promote positive coping strategies, and improve physical health, while social connections provide emotional support, motivation, and a sense of purpose.

Question 15

As an older adult,the production of _____ in the skin upon exposure to sunlight is less than at younger ages.

Accepted Answer

The production of vitamin D in the skin upon exposure to sunlight decreases with age. This is why older adults are more likely to be deficient in vitamin D and may need to take supplements or increase their dietary intake.

Question 16

The RDA for _____ is lower for adults over 70 compared to adults 19-50 years old.

Accepted Answer

The Recommended Dietary Allowance (RDA) for sodium is lower for adults over 70 compared to adults aged 19-50 years old, reflecting concerns about blood pressure and cardiovascular risk in older populations.

Question 17

Taste usually declines more with age than other senses such as hearing.

Accepted Answer

Hearing and vision typically decline more with age than taste. Age-related changes in these senses are more pronounced and common, affecting daily life significantly.

Question 18

Adults should engage in _____ minutes of vigorous-intensity exercise or _____ minutes of moderate-intensity exercise each week.

Accepted Answer

The American Heart Association recommends that adults engage in at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity exercise each week to maintain cardiovascular health. Option C provides these recommended time frames.

Question 19

Adults aged 20-65 years who tend to live the longest are _____ for height.

Accepted Answer

Research has shown that individuals who fall within the normal weight range for their height tend to have a longer lifespan compared to those who are underweight, overweight, obese, or extremely obese.

Question 20

The RDA for vitamin C increases as we age.

Accepted Answer

The Recommended Dietary Allowance (RDA) for vitamin C does not increase with age for adults after the age of 19. It remains constant at 90 mg/day for men and 75 mg/day for women, with adjustments only for pregnant and lactating women.
