Animal vs. Plant Protein: Scientists Find a Surprising Nutritional Difference

Protein is often counted as if all grams are equal. A label may show the same amount of protein in two meals, but the body does not always receive the same nutritional value from them. That difference is now at the centre of new attention around animal and plant protein.

The key finding is not that plant protein is “bad” or animal protein is always “better.” The point is more precise: equal serving sizes can deliver different amounts of essential amino acids that the body can use for muscle-building and repair. SciTechDaily reported that animal-based protein foods provided greater essential amino acid bioavailability than equivalent portions of plant-based protein foods, based on research challenging the idea that all protein-ounce equivalents are nutritionally identical.
