Are all sources of protein created equal?

Not quite. While many plant foods, including nuts and beans, can provide a good dose of protein, the best sources are dairy products, eggs, lean meat and fish, says Donald Layman, an emeritus professor of nutrition at the University of Illinois in the US.

Unlike plant-based proteins, animal protein is complete, meaning it contains the right proportions of the essential amino acids your body can't make on its own.

It's possible to build complete protein from plant-based foods by combining legumes, nuts and grains, but you'd need to eat 20 to 25 per cent more plant-based protein to reap the same benefits that animal-derived sources provide, says Mark Tarnopolsky, who studies nutrition at McMaster University in Ontario, Canada.
