Video 2 of 2 explaining our Best Practice Guidelines. The Best Practice Guidelines have been developed to provide you with step-by-step guidance to selecting the most appropriate dietary assessment tool. Although there are 4 steps to the guidelines: Define, Investigate, Evaluate and Think Through, this video focuses on the last 3, Investigate, Evaluate and Think through. For information on the first step, please see our previous video ‘Best Practice Guidelines: Define’. Just to warn you the clip does contain music, so if you're in a busy office it may be worth putting some earphones in or turning the sound off!
