Polish sandacz fish praised for heart‑healthy nutrients

The sandacz, a large pike‑perch native to Poland's clean, oxygen‑rich rivers, lakes and reservoirs, is widely regarded as the "king of Polish waters." Historically prized by Polish royalty such as Władysław Jagiełło, it remains a coveted trophy for anglers and a favored ingredient for chefs because of its firm, white flesh and minimal bones.

Nutritionally, sandacz is a lean, protein‑rich fish low in fat and cholesterol. A 100‑gram serving supplies full‑value protein, iron, potassium, magnesium and selenium, while providing an exceptionally high amount of vitamin D—about 143 % of the daily requirement. It also contains vitamin B12. These nutrients support cardiovascular health by helping regulate blood pressure, reducing the risk of atherosclerosis, and protecting cells from oxidative stress, making the fish a valuable component of a heart‑friendly diet.
