Protein recommendations are the daily dietary protein requirements for an individual based on that individual's weight.
<h3>What was the dietary protein requirement?</h3>
For a typical sedentary adult, the suggested dietary allowance is 0.8 grams per kilogram of body weight. For instance, 60 grams of protein should be consumed daily by a person who weighs 165 pounds, or 75 kilograms.
Christine has already ingested half of the 40 grams of dietary protein that her doctor recommended. This indicated that she had already ingested roughly 20 grams of the recommended dietary protein and needed an extra source of protein to meet her daily needs. Christie must therefore have four more servings of snacks to complete her daily protein requirements.

The placenta also enables the mother remove waste produced by the fetus into her bloodstream.
