In addition to being delicious, sardines are rich in omega-3 fatty acids and a source of potassium. For this reason, they are excellent allies for heart health and help maintain normal blood pressure (as long as they are not excessively salted). Polyunsaturated fatty acids also protect against cardiovascular disease, help prevent inflammatory conditions, and support learning and memory.

But there’s more. Their richness in B-complex vitamins (B12, niacin, B2, and B6), iodine, and potassium—especially when combined with a healthy lifestyle—benefits the nervous system. Furthermore, sardines contribute to normal psychological function and help reduce tiredness and fatigue.

It is also known that sardines have a positive impact on bone health due to their high vitamin D content. They are one of the fish with the highest calcium levels, particularly when the small bones are consumed.
