Dietary protein, resistance training and health: a call for evidence

Background Purposeful intake of ample dietary protein remains controversial, as illustrated by uncertain and/or dissuasive material in introductory dietetics texts and statements by professional organizations (Lowery L and Huffman J, Dietary Protein in Sport: Still Controversial, ASEP National Meeting, 2008). Common health concerns include undue "stress" on renal function, bone loss, and deleterious effects on other dietary components such as fiber and saturated fat. Particularly dissuasive language has been targeted toward strength athletes.
