What do we mean by essential
and non-essential amino acids?
John has been living in an apartment all junior year, eating a lot of fast food. He has heard that it is "bad for you" because it is too high in calories and
too low in essential nutrients, particularly vitamin A. John looks up the nutrient composition of two of his favorite fast-food meals (see table).
1. If John chooses the Big Mac, fries, and soda, for lunch, how many micrograms of vitamin A would he be consuming? (Hint: You first need to convert
% Daily Value to micrograms of vitamin A.)
Vitamin A
Energy (% Daily

1.5
Soda (20 oz)
240
*Hint: first you need to look-up the daily Value for vitamin A: 900 µg (I just gave you the Daily Value).
For dinner, John has 2 cups of spaghetti with meat sauce, a slice of Italian bread with 1 tsp butter, and a cup of 1% milk.
2. How much vitamin A does this provide? (use iProfile to for this solution)
3.…
