Question
John is 21 years old and lives on his own, goes to school, and works part-time. He smokes about 1 pack of cigarettes per day. He eats breakfast at home and usually brings a sandwich for lunch, but dinner is always a fast-food meal because he is on the run. He recently heard a report indicating that fast-food was low in some vitamins, particularly Vitamin C. John doesn’t want to give up his fast food, so he looks at his other meals to make sure they provide plenty of Vitamin C. John’s averaged dietary intake of Vitamin C is 30 mg.
4. What is John's DRI for Vitamin C?
What percentage of his DRI for Vitamin C does he meet?
Explanation / Answer
The recommended daily intake by the US food and nutrition board shows that men more that 18 years old should take 90milligrams of vitamin C.So the dietary reference intervals for john would be 60-90 mg as per daily value.However smokers require 35mg/day more than non smokers.But the amount john is taking is not sufficient as per DRI value.
The percentage he meets is nearly 48%-50%.
