Question

8. Read the “How to 10-1” box on page 298 of your text. Calculate which food provides more vitamin A per one ounce serving and which is more nutrient dense -- Complete the following chart: Hint: To calculate the vitamin A per one ounce serving, divide the vitamin A, µg RAE by the number of ounces in the serving size; to calculate the nutrient density, divide the µg RAE by the number of kcalories in the serving size. Round fractions to two decimal places. Food Serving Size (kcalories) Vitamin A, µg RAE Vitamin A per one ounce serving Nutrient density (µg RAE / kcal) Corn Flakes, fortified 1 ounce (110 kcal) 205 Carrots ½ cup sliced, boiled, drained – 3 ounces (27 kcal) 665 Banana 1 medium raw – 4 ounces (109 kcal) 4 Milk, fortified 1 cup reduced fat 2% -- 8 ounces (121 kcal) 134 Cheddar Cheese 1½ ounces (171 kcal) 75 Pinto Beans ½ cup cooked -- 2 ounces (117 kcal) 0 Peanut butter 2 tbs – 1 ounce (188 kcal) 0 Egg 1 hard cooked – 2 ounces (78 kcal) 75 Beef Liver 3 ounces fried (184 kcal) 6586 What conclusions can

Answer 1

Food Item	Weight	Kcal	Vitamin A (µg)	Vitamin A per one ounce serving	Nutrient density
Corn Flakes	1oz	110	205	205 µg/oz	1.86µg RAE / kcal
Carrots ½ cup sliced, boiled, drained	3oz	27	665	221.67 µg/oz	24.63µg RAE / kcal
Banana 1 medium raw	4oz	109	4	1µg/oz	0.04µg RAE / kcal
Milk, fortified 1 cup reduced fat 2%	8oz	121	134	16.75µg/oz	1.10µg RAE / kcal
Cheddar Cheese	1½ oz	171	75	50µg/oz	0.44µg RAE / kcal
Pinto Beans ½ cup cooked	2	117	0	0	0
Peanut butter 2 tbs	1	188	0	0	0
Egg 1 hard cooked	2oz	78	75	37.5µg/oz	0.96µg RAE / kcal
Beef Liver	3oz	184	6586	2195.34µg/oz	35.80µg RAE / kcal

Conclusion - Beef is the richest source of vitamin A both in both the criteria of vitamin A per one ounce serving and nutrient dense followed by carrot.
