Study shows greater metabolic response to animal versus plant proteins

Protein from two ounce-equivalents (oz-eq) of animal-based protein foods provides greater essential amino acids (EAA) bioavailability than an equal two oz-eq of plant-based protein foods, according to scientists at Purdue University.

The protein quality of a food or meal (i.e., the EAA content of a meal) is a major factor in determining how the body can use amino acids for muscle and whole-body protein building.

The Dietary Guidelines for Americans (DGAs) puts an emphasis on consuming a variety of protein foods based on ounce-equivalent portions with similar nutritional content. One oz-eq equals one ounce of meat, one whole egg, 0.25 cups of beans or 0.5 ounces of nuts.
