Fish are renowned for their high nutritional value. They are also a source, particularly marine fish, of mineral substances such as phosphorus, selenium, magnesium, or calcium; the latter two are mainly present in the fish skeleton. Fish also contain fluorine, iodine, and vitamins A and D.
Health advantages derived from fish consumption
Fish are a rich source of polyunsaturated omega-3 fatty acids in the blood, which lower the level of overall cholesterol, particularly the LDL fraction, which is responsible for the development of atherosclerosis. Consumption of fish can also lead to an increase in the level of HDL, which is known as good cholesterol. Omega-3 fatty acids also lower the consumer's blood pressure and reduce the risk of blood clot formation. They also decrease arterial blood pressure levels, which reduces the risk of cardiovascular diseases and atherosclerosis. The antioxidant properties of omega-3 fatty acids can also contribute to reducing the risk of cancer and aging processes in the body. Fish is also a source of macro- and microelements, including selenium, which has antioxidant and anticancer properties. It is important to consume fish in appropriate amounts, which can contribute to reducing the risk of cardiovascular diseases and other chronic diseases. However, it is worth noting that fish can also contain heavy metals and other substances that may have negative effects on health.
What fish should be ingested?
The best choice are seafood, as their flesh is extremely rich in unsaturated fatty acids. They include: mackerels, salmons, tunas, sardines, and herrings. Atlantic wild salmon contains around 6.5 g of fat per 100 g, smoked mackerels 13.8 g, sardines in water 12.7 g, fresh herrings 9 g, and salted 18 g. When it comes to heat treatment of fish, cooking or steaming is recommended. An electric grill or aluminum foil can also be used for frying. The use of fat for frying is not recommended, however, if someone cannot give up this method of preparation, they should pay attention to not overheating the fat, as its maximum temperature should not exceed 180°C. It is also important to check the fat content of fish sold already in processed form, such as salted herrings, smoked mackerels, or tuna in oil. The process of salting or smoking increases the fat concentration in the product, which results in a higher proportion of unsaturated fatty acids. The situation is different when the fish is preserved, which can lead to a significant loss of nutrients.
General description
In the case of choosing fish for purchase, it is ultimately essential to note that its freshness is a key factor. The fish's eyes should not be hazy or murky.
