Fresh fish or canned fish, which is better to eat? It is better to eat fresh fish that has been thoroughly washed and cleaned. However, fish that’s been caught in the deep seas and canned, like Norwegian salmon and shrimp, is fine in the short-term.
When it comes to fish and meat, it is always better to eat it fresh, as the nutrition from fresh food will always be higher than that found in canned or tinned food. Ensure though that the fresh fish or meat has been washed and cleaned thoroughly before cooking. The process of cooking also removes chemicals to a large extent.
