Both groups would undergo testing to measure cardiovascular health. In this study, the independent variable is fried food consumption, which is measured by recording the amount and type of fried food consumed by the intervention group. Cardiovascular health would be the dependent variable. The research would be conducted as a randomized controlled trial, a type of experimental study.
