Ch 6 Case Study: Protein Adequacy

What is the protein RDA per kilogram of healthy body weight?

0.8 g

Erin loves whole grains. Suppose she makes herself a snack from one serving of grains and one cup yogurt topped with a serving of fresh strawberries. How much protein is in her snack?

10 to 11 grams

What percentage of total energy intake should come from protein?

10 to 35%

Remembering that protein provides 4 kilocalories per gram, what percentage of Erin's current total energy intake comes from protein?

13.3%

Erin enters her profile information into the MyPlate website and discovers that she needs 2000 kilocalories per day to achieve a healthy body weight. Which of the following menu plans would allow her to meet the 2000-kcal intake while following the MyPlate lacto-ovo vegetarian guidelines?

2 cups of various fruits; 2.5 cups of various vegetables; 2 eggs; 2 slices bread; 1cup lowfat milk; 1 Tbsp peanut butter and 2 Tbsp strawberry jam spread on 2 slices of bread; 1 cup ice cream; ½ cup beans over 1 cup rice; ½ oz. nuts sprinkled over 1 cup lowfat yogurt; 5 oz. wine

Assuming a healthy weight for Erin is 141 pounds, what is her recommended daily protein requirement?

51 g

What can be said about Erin's protein intake?

Although it falls within the recommended range in terms of the percentage of total energy intake, her protein intake is less than recommended in terms of the absolute amount needed to maintain a healthy body weight.

What features of Erin's diet would explain why she has been sick more than usual?

Her low energy intake (1200 kilocalories) is forcing the body to use some of the limited dietary protein to meet energy needs rather than make needed antibodies to fight an infection.
