There are many methods that can be used to assess dietary intake - for example, using a food frequency questionnaire (FFQ), food diary or a 24-hour recall. Deciding what is the most appropriate dietary assessment tool can be difficult, as each have their own strengths and weaknesses, which can then have implications on research studies themselves. Previously, we wrote an article to help you decide which dietary assessment method to use. You can also download a free cheat sheet on Dietary Assessment Methods covering all you need to know about food diaries, FFQs and 24hr recalls.
