The “gold standard” is randomized clinical trials of dietary interventions on hard endpoints such as cancer and heart disease. However, such trials are often infeasible due to high cost, low long-term compliance, and potential ethical issues. In the absence of evidence from such trials, the strongest study design would be well-designed prospective cohort studies, in which a large number of healthy participants are followed for years or decades for disease outcomes. Cohort studies are usually superior to retrospective case-control or cross-sectional studies, which are prone to biases due to recall of dietary factors and selection of control participants. Animal studies can help understand disease mechanisms but the results may not apply to humans. Smaller human dietary intervention trials on intermediate biomarkers such as blood glucose or cholesterol can also help to illuminate biological mechanisms, and evidence from such trials is complementary to that from large cohort studies. In the end, combined evidence from several types of studies—prospective cohort studies and human intervention trials in particular—can be used to inform dietary guidelines and policies. Summarizing evidence using meta-analyses or systematic reviews can be helpful, but meta-analyses should be conducted with caution and interpreted in light of the totality of the evidence.
