Question

Quizplus · Accepted Answer

Epidemiological studies are most commonly used as evidence for the benefits of phytochemicals. These studies look at large populations and analyze their diet and health outcomes to see if there is an association between consuming certain foods or nutrients (in this case, phytochemicals) and a reduced risk of certain diseases. While experimental studies (B) can provide more direct evidence, they are often done on animals or in cell cultures rather than in humans, and may not fully translate to humans. Survey studies (C) and retrospective studies (D) may provide insight but do not have the same level of evidence as epidemiological studies.
