Question

Erin is a 28-year-old professional woman who is 5 feet 8 inches tall and vigilantly maintains her weight at 118 pounds by following a lacto-ovo (non-fat milk and egg whites only) vegetarian diet that supplies approximately 1200 calories a day. With her understanding that protein should provide between 10 and 35 percent of her daily calories, she reasons that her daily intake of 40 grams of protein from milk, eggs, legumes, and nuts is adequate for her needs. She is concerned, however, that she has been sick more than usual and has experienced two stress fractures in her leg over the past three years while exercising.

What is the protein RDA per kilogram of healthy body weight?
a. 1.2 g
b. 0.8 g
c. 1 g
d. 0.4 g
e. 0.6 g

Answer 1

Answer: B 0.8g is the protein RDA (Required Dietary Allowance) per kilogram of healthy body weight.

Step-by-step explanation:

An individual needs 0.8g of protein to meet his/her daily nutritional requirements.

0.8g of protein is needed to keep the body protein level at an optimum and not the specific amount one should eat everyday.

To determine Erin's daily protein intake,you multiply her weight of 118pounds by 0.36 which is a standard figure.

Taking into consideration her;

Age-28years

Weight-118pounds

Gender-Female

Height- 5feet, 8inches

Using a Dietary Reference Intake Calculator, Erin's Body Mass Index is 17.9, her estimated caloric need is 2393kcal/day and her required dietary allowance for protein is 43g.
