It is very common to think that eating fish, whether oily or white, is synonymous with maintaining a healthy lifestyle. However, do we really know what oily fish or white fish gives us? Which is lighter? Which is more suitable for a low-fat diet? From Pescados y Congelados Guerrero we tell you all about it.
Which is better, oily fish or white fish?
Blue fish get their name as a common characteristic among the fish in this category. They need large amounts of fat for their long journeys, which influences their skin colour, which is a shade of blue.
This type of fish is a great source of omega-3 fatty acids, which is considered an essential and necessary heart-healthy fat that our body does not generate on its own. Omega-3 is very beneficial for cardiovascular health, as it helps to reduce blood pressure and prevent cardiovascular disease, among other benefits. This is why they recommend eating oily fish 2 to 3 days a week.
Unlike oily fish, white fish contains much less fat and calories. This makes it a much easier food to digest. It is renowned for its high levels of protein, which is necessary for the correct functioning of our body. They also provide large amounts of B vitamins, iron, phosphorus and calcium, among others, as well as contributing to development and growth, as well as combating hypothyroidism and osteoporosis.
One trick to differentiate between them is the shape of their tails: blue fish have an arrow-shaped tail and white fish have a rounded tail.
