Nice piece of research from the Journal of Nutrition (May) where scientists ran a randomised controlled trial comparing animal protein to plant protein (beef, pork and eggs versus red kidney beans, tofu and peanut butter) when protein per gram was matched across both groups. The results showed animal protein was both superior in terms of its anabolic response as well as suppressing protein breakdown. Researchers equated the findings with the superior amino acid content of the animal products.

Apart from its main finding, I think this study also drives another nail into the coffin of the ‘a calorie is just a calorie’ myth.
