IAFNS is committed to sharing the results of the research we support, regardless of the outcomes. Our publications undergo stringent peer-review by qualified experts prior to publication and include disclosure of all sources of funding.
IAFNS is one of six partners whose goal is to improve public health and the sharing of open data by expanding and enhancing the USDA National Nutrient Database — now known as USDA FoodData Central — with nutrient composition and ingredient information on branded and private label foods to better reflect the food supply.
Interest in improving accuracy, and replacing self-reports with passive tools when estimating energy balance (EB) using intake (EI), storage (ES) and expenditure (EE)) has led to wide use of commercial devices e.g. Fitbits. A study with free-living adults looked at repeatability, and measurement error of these devices and showed varying degrees of validity when used to estimate EB compared to gold-standard techniques, with EE measures being the most robust and ES the poorest.
The science and tools of measuring energy intake and output in humans have rapidly advanced in the last decade. Engineered devices such as wearables and sensors, software applications, and Web-based tools are now ubiquitous in both research and consumer environments.
Fundamental to developing a specific dietary recommendation for a sodium-to-potassium ratio is a well-designed human intervention trial.
