Layla loves pumpkin spice, and one of her favorite seasonal treats is a
Pumpkin Spice Latte (PSL), which she knows is 380 calories. Hearing that
Starbucks just released a new Pumpkin Cream Cold Brew, she is wondering

Pumpkin Cream Cold Brew contains 12 g fat, 31 g carbohydrate, and 3 g
protein, does it contain more or fewer calories than the PSL? - ANSWER The
new Pumpkin Cream Cold Brew drink is 244 calories, which means it contains
fewer calories than the traditional PSL beverage

,Latte that is 100 calories. If this latte contains 5 g of protein and 14 g of
carbohydrate, then how many grams of fat must it contain? - ANSWER 3
grams of fat
Alcohol is a macronutrient because it provides 7 cal/g of energy. - ANSWER
Flase
Julia is trying to teach her sister about the difference between
macronutrients and micronutrients. What should Julia tell her sister? -
ANSWER We find macronutrients in food in relatively larger amounts than
micronutrients.
B. Macronutrients are present in the body in relatively large amounts
compared to micronutrients.
C. Micronutrients have daily requirements that are relatively smaller than
that of macronutrients.
(All of the above are CORRECT)
Abel's DRI for vitamin E is 15 mg. If his intake of vitamin E is marginal, which
of the following could NOT have been his actual level of intake? - ANSWER
11 mg
Abel is studying his dietary analysis. He sees that his intake for carbohydrate
is expressed as 48% of his total calories and that his intake of fat is 37% of
total calories. He has two questions:
· Why aren't these values expressed as a percent of a fixed number?
· Are these in fact "good" levels of intake relative to what is recommended?
Which of the following is/are CORRECT regarding these questions? -
,ANSWER If carbohydrate and fat levels were expressed as a percent of a fixed
number, as is true for the other nutrients, many people would be at risk for
obesity if they were to try and meet the recommendation.
Abel's carbohydrate intake is within the recommended range.
(A and B are correct)
When the DRIs were first developed, the primary nutrient-related public
health concerns were____________. Therefore the first DRIs focused on
identifying optimal levels for _____________. - ANSWER deficiency
diseases.....vitamins, minerals, and protein
Abel is now examining his protein intake and realizes that he has two
percentages listed on his printouts—one is a percent of his total calorie intake
and the other is a percent of his DRI. Which of the following statements
concerning these values is/are CORRECT? - ANSWER The DRI for protein,
expressed as a percent of total calories, exists because protein contributes
calories to our diet.
Amanda has been feeling tired a lot recently. "I think I need to add some

Someone living in a refugee camp
Someone consuming above the UL
A typical American - ANSWER Deficient intake of micronutrients
Excess intake of micronutrients
, Marginal intake of micronutrients
Which of the following is/are CORRECT about the DRIs? - ANSWER The DRIs
are set two standard deviations above the EAR because if they were set at the
EAR, then a large portion of the population would not be meeting their
nutrient needs.
Although Americans get more than enough of the macronutrients today,
getting too little of the micronutrients is a problem due to a wide variety of
factors, including lack of knowledge, lack of money, limited access to foods
that are rich in micronutrients - ANSWER True
Over the years, an increased understanding of nutrient needs among older
adults has led to a general decrease in most of the DRIs for this age group as
researchers have realized that the relative inactivity in this population
translates into lower nutrient requirements. - ANSWER False
The DRI for vitamin K is 120 mg and there is no UL determined for vitamin K.
When Raquel gets her food diary printout, she discovers that her intake of
vitamin K is 130 mg. Which of the following is/are CORRECT about her
