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? - correct 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? - correct 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
_____________. - correct answer deficiency diseases.....vitamins, minerals, and protein
