Herring and mackerel are outstanding sources of vitamin D and Omega-3. According to NIFES (Norwegian National Institute of Nutrition and Seafood Research), 100 g herring gives twice as much vitamin D as the daily recommendation for both children and adults.
– “Herring is a very good source of vitamin D”, says researcher Lisbeth Dahl in an report published 10.04.2015.
According to the same research, the Norwegian spring spawning herring (NVG), contains almost twice as much vitamin D as the Pacific herring, 25 µg versus 14 µg, and almost five times what you will find in mackerel.
When measuring Omega-3, both herring and mackerel score high, but it seems that nobody beats the mackerel, which is an outstanding source of the Omega-3 fatty acids EPA and DHA. What the researchers also found, was that the content of Omega-3 in the mackerel found in Norwegian waters, is almost twice what found in the Japanese mackerel (4,9 g/100g versus 2,8g/100g).
