Nutrition and health editorial: How to present and interpret research findings in nutrition and dietetics research

Nutrition and Health as a nutrition and diet-focused journal aims to publish the most up-to-date and high-quality research papers for health professionals’ lifelong information and new knowledge acquisition. It has been highlighted and long discussed that nutrition and dietetics research requires advanced and complex methodological approaches due to the nature of the metrics used. For instance, when assessing a group’s or individual’s dietary habits, the level of accuracy is relatively low due the high variance of dietary habits between seasons, between days and within time for the same individual. This can become even more complex when a larger group of individuals is being observed, as between-individuals variance also plays a key role in reducing the accuracy of information. At the same time, the tools we use to assess all of the above have important drawbacks themselves. Thus, we should be aware that that all available tools have important error levels; 24-hour recall might not offer a wide variety of information for long-term food consumption, self-completed diaries might affect a person’s intake and a Food Frequency Questionnaire has important recall bias.
