Protein energy ratio (Protein energy percentage)
It is a quantitative measure for assessment of protein.
It measures the percentage of energy that is provided by the protein in the food.
PE percent = Energy from protein / Total energy in diet x 100
If the PE ratio is less than 4%, the subject will be unable to eat enough to satisfy protein requirements.
