Globally, about two billion people suffer from “hidden hunger” – a chronic deficiency of vitamins and minerals. The health effects of this form of malnutrition can be severe, especially for children. They include increased risk of poor cognitive development, impaired growth and early death. Ironically, our latest research found that many coastal countries where hidden hunger is rife, have plenty of nutritious fish just off their coast. Yet these fish are not reaching those who need them the most.
Fish are a source of protein and omega-3 fatty acids and are rich in calcium, iron, zinc, vitamin A and vitamin B12. Fish also increase the “bioavailability” – that is, increase absorption – of nutrients provided through other foods eaten in the same meal.
Humans eat more than 2,000 species of fish, but the nutritional value of these species varies greatly. Until recently, we didn’t know enough about this variability to advise fisheries and policymakers to help them address malnutrition.
