The Importance of Fish and Omega-3 Fatty Acids

Fatty acids in oily fish are said to be necessary for normal growth and development. The role of these fatty acids in the diet, especially the balance between omega-3 and omega-6, has long been a subject of research. These fatty acids, which the body cannot produce on its own, are essential compounds that must be obtained from food. Below are the roles of omega-3 and omega-6 in the body, which foods contain them, and what to keep in mind in daily consumption. What are omega-3 and omega-6? Linoleic acid (the omega-6 family) and linolenic acid (the omega-3 family), which belong to the polyunsaturated fatty acid (PUFA) group, are considered essential fatty acids that the body cannot synthesize. For this reason, these fatty acids are said to need to be obtained regularly from food. In the body, ARA is synthesized from linoleic acid among the omega-6 fatty acids, while EPA and DHA are synthesized from linolenic acid among the omega-3 fatty acids. However, because this synthesis process is quite slow, obtaining EPA and DHA directly from sources such as fish and fish products is considered important nutritionally. Which foods are considered rich sources? Oily fish are considered a good source of omega-3 (EPA, DHA); salmon, mackerel, sardines, and anchovies are among the notable varieties in this group. Under EU food labeling rules, foods containing at least 80 milligrams of EPA and DHA per 100 grams and per 100 kilocalories are considered high in omega-3 fatty acids. Omega-6 is abundant in sunflower oil, corn oil, and processed foods; although plant sources such as flaxseed and walnuts are also known to contain omega-3, they are not considered as effective a source as fish because the conversion process from these sources is very slow. Ratios for fatty acids are a matter for an individual nutrition plan; this article focuses on preparing fish in the kitchen. The recommended omega-6/omega-3 ratio is said to be less than 4. Fish and different oil sources can be used on the menu according to the recipe's flavor. The type and amount of oil are chosen based on how the dish is prepared. Weekly fish consumption recommendation The American Heart Association recommends eating 2 servings of fish, particularly fatty fish, per week. Fish can be served on different days of the week, prepared using different cooking methods. To make regular fish consumption sustainable, varying it with different cooking methods and recipes can help. Grilled, baked, or steamed fish offers balanced options in terms of both flavor and nutritional value. Using different oils in the kitchen changes a dish's flavor and texture. Choosing olive oil instead of sunflower oil in salad dressings is a simple change that can help achieve this balance. Freshness is an important criterion when buying fish; bright eyes, firm flesh, and a mild smell are considered signs of fresh fish. Cooking freshly purchased fish the same day or the next day helps preserve both its flavor and fatty acid quality.
