Explanation:

A cohort study follows a group of individuals (a cohort) over time to observe the development of an outcome (heart disease in this case) and how exposure (dietary habits) relates to it. A case - control study looks back from the outcome. An experimental study involves intervention. A cross - sectional study is a snapshot in time. Since the research team is following participants over 10 years, cohort study is appropriate.

1. Cohort
