Saury fish
Sardines are tiny, soft-boned, saltwater fish. Sardines are typically sold in cans containing sauces, water, or oil, but they are also available raw. They are extremely nutritious because they contain nearly every nutrient in sufficient quantities. One cup (150 grams) of dried sardines contains 554% of the recommended daily allowance of vitamin B12. In addition, sardines are an excellent source of omega-3 fatty acids, which promote cardiac health and reduce inflammation.
