What are the 2 types of assessment methodology for assessing nutritional intake
Retrospective: Examination of food taken in the past
Prospective: Monitoring ongoing food intake

3 days.
<3 days: High intra-individual variability
> 4days: Greater subject compliance required
What may be limitations faced when assessing dietary intake for athletes?

Inaccurate reporting to improve perception of what is consumed
