Affordable Nutrient Density of Aquatic Foods in the FAO uFISH Database Assessed Using Nutrient Rich Food Price Index
Fish and shellfish have the potential to improve global public health by alleviating protein-energy malnutrition and closing micronutrient gaps. The aim of this study was to determine nutrient density of fish and shellfish in the FAO/INFOODS uFISH database using the Nutrient Rich Food (NRF) index and compare their affordability in relation to protein and priority micronutrient content. Two versions of NRF index were applied to the uFISH database. NRF6.2 was based on 6 priority micronutrients: iron, zinc, calcium, vitamin A, vitamin B12, and folate. NRF9.2 used protein, calcium, iron, potassium, magnesium, selenium, vitamin A, vitamin D, and omega-3 fatty acids. The NRF6.2 score identified mollusks, and especially bivalves, as the best aquatic source of priority micronutrients. The NRF9.2b identified small pelagic fish as the most nutrient rich, followed by bivalves. Mackerel, tilapia, squid, and mussels provided the most protein, NRF6.2 nutrients, and NRF9.2b nutrients per penny. The results of this analysis confirm that fish and shellfish can be an affordable source of protein, omega-3, and priority micronutrients.
