Eating tinned fish is a practical, affordable, and often delicious way to get a variety of nutrients in a small serving of food. Tinned fish contains high levels of omega-3 essential fatty acids, which cannot be produced by the body and must be consumed through food or supplements. Omega-3s provide a variety of health benefits, such as helping to prevent heart disease, reducing the risk of diabetes, and lowering blood pressure. Eating tinned fish can also provide you with essential vitamins, such as vitamin D, which is needed for bone health, and vitamin B12, which supports metabolic functioning. Tinned fish is a great source of calcium and an amino acid called taurine, which has anti-inflammatory and antioxidant properties. Alongside its other benefits, tinned fish is a handy source of protein that can easily be added to sandwiches, salads, and many other dishes. Salmon, mackerel, anchovies, sardines, and herring are generally the most nutritious varieties of tinned fish, which can be remembered using the acronym “SMASH.”
