Summary
This record represents an update to the USDA FoodData Central database, specifically focused on marine foods. FoodData Central is the principal US government nutritional composition reference, and updates of this kind typically reflect improved analytical methods, expanded species coverage, or revised sampling protocols. The marine foods dataset is of particular relevance to research on dietary omega-3 intake, seafood's role in nutrient-dense diets, and food labelling accuracy.
UK applicability
FoodData Central is a US government resource and its compositional data may not fully reflect the species, aquaculture practices, or seasonal variation relevant to UK seafood. However, it serves as a widely used international reference, and UK researchers may draw on it for comparative purposes or where equivalent UK datasets (such as those from McCance and Widdowson's food composition tables) have gaps.
Key measures
Nutrient composition per food item (e.g. omega-3 fatty acids, protein, minerals such as iodine, selenium, zinc; vitamins); number of food items updated or added to the database
Outcomes reported
The dataset update reports revised and expanded nutritional composition values for marine foods, likely including macro- and micronutrients, fatty acids, and minerals across a range of seafood species. It provides a reference resource for researchers, dietitians, and policymakers assessing the nutritional contribution of marine-sourced foods.
