An observational study would be the best choice to investigate the association between consuming diets high in sodium during adolescence and developing high blood pressure in adulthood. This type of study involves observing and recording data on individuals without manipulating any variables. It allows researchers to collect data on the potential risk factor (sodium intake) and the outcome (high blood pressure) over a long period of time, which is important for determining causality. An experimental study, on the other hand, involves manipulating the independent variable (sodium intake) and may not be ethical or feasible in this case. Double-blind and single-blind studies are experimental designs that involve blinding participants or investigators to the intervention, but they do not apply to observational studies.
