Given the inherent complexity of measuring individual dietary intakes and patterns, nutrition researchers employ a wide variety of scientific approaches to address specific health questions. What are the research designs used in nutrition research, and how do they contribute to the evidence base that shapes dietary recommendations and public health policy?

Over 70% of news reports on diet and health are based on observational studies, leading to frequent headlines that seem to contradict previous findings. To properly evaluate nutritional claims, it is crucial to understand what are the two main types of studies in nutrition: observational studies and experimental studies. These distinct research methods provide different levels of evidence and are used for different purposes within nutrition science.
