Question: is pickled herring good for you?
Answer: As with fresh herring, pickled herring is an excellent natural source of both vitamin D3 and omega-3 fatty acids. It is also a good source of selenium and vitamin B12. Just 100 grams may provide 680 IU of vitamin D, or 170% of the DV, as well as 84% of the DV for selenium, and 71% of the DV for vitamin B12.
