Protein sources can be ranked by their digestibility. Digestibility refers to how much of ingested protein is absorbed and utilized by the body. Animal protein sources tend to be among the best digested protein sources. Dairy, eggs, and isolated protein powders tend to be the most completely digested protein sources. After these, meat and soy products are a close second.

On average, plant-sourced protein is much less efficiently digested in part due to cellulose–a component of plant cell walls that cannot be broken down by the human gut. Processed plant protein sources can be healthier than non-processed whole food options because of this; the processing of plant protein can break down cellulose and make the amino acid contents more accessible. Some exceptions are mycoprotein (a fungus-based protein) and nutritional yeast. Because fungus and yeast do not contain cellulose, they are much better digested and absorbed.
