Although our freshwater fish consumption is on par with the European average, statistics show that overall, Hungary is still among the nations that eat the least fish in the world. Real change will only come if a new generation grows up for whom weekly fish consumption is a natural habit learned at home.
A 1998 study revealed that among those who ate seafood once a week or more, the incidence of sudden cardiac death was 52% lower than among those who only consumed it once a month. In Hungary, where more than half of all deaths are caused by heart and circulatory diseases, this fact is particularly striking.
Fish Oil
Fish meat has a loose tissue structure, is easy to digest, but due to its high water content, it spoils quickly. With its favorable balance of energy, fat, and an average of 15–20% protein, fish — when prepared properly — fits perfectly into weight-loss diets. Based on fat content, we can distinguish fattier fish (e.g., carp, catfish, tuna, mackerel, salmon, herring) from leaner ones (e.g., silver carp, grass carp, pike perch, cod, hake). Composition also depends on the fish’s age and diet — for example, a four-year-old fish can have up to four times the fat content of a juvenile.
Fish oil — especially from marine species — contains polyunsaturated fatty acids (omega-3s), which are vital for health. Since the human body cannot produce these essential fatty acids, we must obtain them from our diet. They are proven to prevent blood clotting, lower blood lipid levels, regulate blood pressure, and reduce the risk of coronary heart disease.
Some omega-3 fatty acids also play a role in brain and eye development. During the last stage of pregnancy, they accumulate in the fetal brain, which is why premature babies — who miss this developmental stage — require supplementation through breast milk or formula. For this reason, seafood is especially recommended for pregnant and breastfeeding women.
Fish is an excellent source of fat-soluble vitamins, especially vitamins A and D. These help the body neutralize free radicals (substances that damage blood vessels and may cause cancer) and boost resistance to disease.
Among water-soluble vitamins, fish is particularly rich in B1 and B2, and in terms of minerals, it provides significant amounts of iron, selenium, zinc, and iodine. Canned fish, thanks to their soft, edible bones, are also high in calcium.
It is less well known that cooking and frying do not significantly reduce the content of polyunsaturated fatty acids — meaning their health benefits remain intact. Moreover, not only fresh fish but also processed fish products contain fish oils. Among marine fish, mackerel is the richest source of polyunsaturated fats, while among freshwater species, silver carp, bighead carp, and sterlet stand out.
