1. Types of Research Studies and How To Interpret Them – Nutrition
Researchers use many different types of study designs depending on the question they are trying to answer, as well as factors such as time, funding, and ethical ...
The field of nutrition is dynamic, and our understanding and practices are always evolving. Nutrition scientists are continuously conducting new research and publishing their findings in peer-reviewed journals. This adds to scientific knowledge, but it’s also of great interest to the public, so nutrition research often shows up in the news and other media sources. You might be interested in nutrition research to inform your own eating habits, or if you work in a health profession, so that you can give evidence-based advice to others. Making sense of science requires that you understand the types of research studies used and their limitations.
2. The Scientific Method – Nutrition - Open Oregon Educational Resources
Missing: standardized | Show results with:standardized
Similar to the method by which a police detective investigates a crime, nutritional scientists discover the health effects of food and nutrients by first making an observation and posing a question that they’d like to answer. Then they formulate a hypothesis, test their hypothesis through experiments, and finally interpret the results. After analyzing additional evidence from multiple sources, they may form a conclusion on whether the food suspect fits the claim. This organized process of inquiry used in forensic science, nutritional science, and every other science is called the .

Dietary Reference Intakes (DRIs) are reference values that are quantitative estimates of nutrient intakes to be used for planning and assessing diets for ...
The development of DRIs expands on the periodic reports called Recommended Dietary Allowances, which have been published since 1941 by the National Academy of Sciences. It is expected that as additional groups of nutrients and food components are reviewed over the next few years, the process and initial models developed will evolve and be further refined. As new information or processes develop, reference intakes will be periodically reassessed in keeping with this evolving process.

FAQs
What type of research provides convincing evidence about relationships between nutrients and health? ›
Randomized controlled trials provide the strongest evidence of a causal relationship between an exposure and health outcome. However, randomized trials of dietary interventions have several limitations and are often unfeasible for ethical or practical reasons.
What is the science of nutrition describe the types of research studies and methods used in acquiring nutrition information? ›The science of nutrition is the study of the nutrients in foods and the body's handling of those nutrients. Epidemiological studies, case-control studies, animal studies, and human intervention (or clinical) trials are all used to acquire information.
Is the scientific study of how nutrients and compounds in foods affect body functions and health? ›Nutrition is the study of nutrients in food, how the body uses them, and the relationship between diet, health, and disease. Nutritionists use ideas from molecular biology, biochemistry, and genetics to understand how nutrients affect the human body.

Which of the following study types is considered the most reliable evidence for a nutritional or medical research claim? ›Systematic Reviews and Meta Analyses
Well done systematic reviews, with or without an included meta-analysis, are generally considered to provide the best evidence for all question types as they are based on the findings of multiple studies that were identified in comprehensive, systematic literature searches.
Observational studies that describe factors correlated with human health are also called epidemiological studies. One example of a nutrition hypothesis that has been investigated using observational studies is that eating a Mediterranean diet reduces the risk of developing cardiovascular disease.
What is the study of nutrients and their relationship? ›Nutritional Sciences is the study of food, nutrients, and other food substances, the intake and biochemical processing of food substances, their relationship to health and disease, and the application of this information to policy and programs.
What is the evidence based approach to nutrition? ›This approach to nutrition emphasizes the importance of rigorous scientific research in determining what constitutes a healthy diet and nutritional needs and seeks to dispel myths and misinformation about nutrition that are not supported by current scientific evidence.
