Seafood as a nutrient-rich food

Seafood is a valuable source of protein, omega-3 fatty acids, vitamins, and minerals. It provides essential nutrients that support tissue growth, immune function, and overall health.

Protein content and absorption

Proteins from animal sources, including seafood, are considered complete because they contain all nine essential amino acids. These are the building blocks of proteins that the body cannot produce on its own. Plant-based proteins often lack some of these amino acids but can be combined to form a complete profile. Animal proteins are also more easily absorbed by the body, with absorption rates ranging from 90 to 99%.

Omega-3 fatty acids and health benefits

Omega-3 fatty acids, particularly EPA and DHA, are crucial for heart health, brain function, and reducing inflammation. These nutrients are found in fatty fish such as sardines, mackerel, and salmon. The recommended daily intake of DHA and EPA is 250 mg each, but more than 90% of the French population does not meet this standard.

Vitamins and minerals in seafood

Seafood is also rich in various vitamins and minerals. Vitamin A supports vision and the immune system, while B-group vitamins such as B3, B6, and B12 help with energy metabolism and nervous system function. Fatty fish are a good source of vitamin D, which is essential for bone health. Minerals like calcium, iodine, selenium, phosphorus, and iron are also present in seafood, with sardines being particularly high in calcium and phosphorus.

Nutritional variation and preservation

The nutritional content of seafood can vary depending on the species, season, and environment. Factors such as water temperature and food availability influence the fat content and omega-3 levels in fish. Canning is a preservation method that retains most of these nutrients through heat treatment, allowing for long-term storage without significant loss of nutritional value.

Sustainable seafood and dietary recommendations

Phare d’Eckmühl, a French cannery, focuses on sustainable fishing practices and ensures the quality and traceability of its products. The National Nutrition and Health Program (PNNS) recommends consuming fish twice a week, alternating between fatty and lean species. Canned seafood offers a convenient and accessible way to meet these dietary guidelines.
