Phyllis is analyzing her intake of Vitamin Z for the food diary project. She consumes 700 mcg of
vitamin Z per day during her food diary project. The DRI for Vitamin A is 1000 mcg/day and the
UL is 3700 mcg/day. Which of the following is/are CORRECT about Phyllis' Vitamin A intake?
A. She is currently consuming 170% of the DRI for Vitamin A, which while above 100%, is still
not a concern because she is still below the UL.
B. She is currently consuming 70% of the DRI for Vitamin A, which means that even though her
intake is less than 100%, it is not marginal.
C. Phyllis' intake of Vitamin A is just 3000 mcg away from the UL, so she should be concerned
about toxicity and seek to lower her intake. - correct answer ✔✔B. She is currently consuming
70% of the DRI for Vitamin A, which means that even though her intake is less than 100%, it is
not marginal.
Phyllis is looking at the results of her food diary analysis and sees that she has averaged 53% of
the DRI for Vitamin D, 115% of the DRI for Vitamin C, and is getting 40% of her total calories
from protein. Which of the following accurately describes her levels of intake?
A. Her Vitamin D and protein intake would both be classified as marginal.
B. She has marginal intake of Vitamin D and is over-consuming Vitamin C.
C. Her protein intake is above the recommended range, but her Vitamin D intake is marginal.
D. Her Vitamin C intake would be classified as excess. - correct answer ✔✔C. Her protein intake
is above the recommended range, but her Vitamin D intake is marginal.
As Phyllis reflects on her food diary analysis, she notices that many of her levels of intake vary
widely from day-to-day. For example, on some days she consumed very little iron, while on
, other days she has well above the DRI for iron. Overall, she has adequate intake of iron. What
should Phyllis do?
A. Seek to consume more high iron foods each day. Her intake is likely marginal because she is
not consuming adequate iron each day.
B. Because her overall intake of iron is adequate, she can continue eating as she has been. The
DRIs are designed to be met over a period of time, not each and every day.
C. Aim for a more balanced diet so that she is close to the DRI most every day; wide swings can
increase the risk for a variety of different diseases as the body struggles with nutrient
uncertainty. - correct answer ✔✔B. Because her overall intake of iron is adequate, she can
continue eating as she has been. The DRIs are designed to be met over a period of time, not
each and every day.
Last week, your roommate Satoko ate an orange for lunch every day; however, this week, she
ran out of oranges and hasn't eaten any. She confesses to you that she is worried that she might
develop scurvy and asks you what you think. What should you tell Satoko?
A. "Satoko, you should not worry about developing scurvy, since it is a deficiency disease that
tends to occur from little to no intake of Vitamin C over weeks to years. You likely have other
sources of vitamin C in your diet, putting you at little risk for developing this deficiency disease."
B. "Scurvy is the result of less than optimal intake of vitamin C over the course of years. While
this might put you at risk for chronic disease, Satoko, not eating an orange this week will likely
have little impact on the likelihood you will develop this chronic disease." - correct answer
✔✔A. "Satoko, you should not worry about developing scurvy, since it is a deficiency disease
that tends to occur from little to no intake of Vitamin C over weeks to years. You likely have
other sources of vitamin C in your diet, putting you at little risk for developing this deficiency
disease."
If the DRIs for fat and carbohydrate were expressed in absolute gram amounts as they are for
vitamins and minerals a consequence could be:
