AMDR=acceptable macronutrient distribution range.
EAR=estimated average requirement.
Smoking status was not considered; smoking may change vitamin C requirements.
Comparison to EAR for ages 50 y and older are difficult because 10% to 30% of older people may malabsorb food-bound vitamin B-12.
AI=adequate intake.
P<0.05 between plausible and implausible reported energy intake.
P<0.01 between plausible and implausible reported energy intake.
