Sardines may be small in size, but they pack a substantial nutritional punch. Rich in omega-3 fatty acids, calcium, and vitamin D, sardines support bone health and cardiovascular function. Their small size means they are often consumed whole, providing the added benefit of calcium from their tiny, edible bones. Sardines are also one of the most sustainable fish choices, as they reproduce quickly and are abundant in the wild. Whether enjoyed fresh, canned, or smoked, sardines offer a convenient and affordable way to boost your nutrient intake. Their robust flavor and versatility make them a delightful addition to salads, pastas, or simply on toast.
