Fish is one of the most recommended foods in a balanced diet, but not all species should be consumed in the same way. Despite the popularity of salmon and tuna, nutritionists point to small blue fish, such as sardines, mackerel and anchovies, as especially interesting options for protecting the heart and brain.
According to the Spanish newspaper, these fish are rich in proteins, vitamins, minerals and omega-3 fatty acids, nutrients associated with good cardiovascular and brain function. At the same time, because they are small species, they tend to accumulate less mercury than larger fish, such as tuna.
The recommendation does not mean abandoning other species, but varying consumption throughout the week. Alternating between blue fish and white fish allows you to enjoy different nutritional benefits and reduce potential risks associated with repeated consumption of the same species.
Small blue fish stand out
Among the most valued options are sardines, mackerel and anchovies. These fish stand out for their omega-3 content, a fat considered beneficial to the body.
Omega-3 fatty acids help modulate inflammatory processes and contribute to heart and vascular health. Therefore, they are often associated with protecting the heart and good brain function.
The great advantage of small blue fish is the balance between nutritional value and less exposure to contaminants. As they are smaller species, they accumulate less mercury throughout their lives.
This detail makes them a smart choice for those who want to include fish regularly in their diet, without always relying on species like salmon or tuna.
Salmon is recognized for its nutritional value and healthy fat content. Still, it can be more caloric due to its higher concentration of fat.
Tuna, on the other hand, is a relevant source of protein, but it raises more concerns due to its mercury content, especially when consumed very frequently.
For this reason, many experts argue that the ideal is to alternate between several species. This strategy allows you to maintain the benefits of fish in your diet and reduce exposure to possible risks.
Variety is especially important for more sensitive groups, such as pregnant women and children, who must pay greater attention to the type of fish consumed and how it is prepared.
White fish should also be included in the diet
In addition to blue fish, species such as cod and hake are good options to include in meals. These fish are high in protein and low in fat.
Because they have a milder flavor, they can be a practical choice for those who don’t like fish with a more intense flavor. They are also versatile and easy to prepare in simple dishes.
White fish can help balance your weekly diet, especially when combined with a serving or two of omega-3-rich fish.
The general recommendation is to consume fish two to three times a week, varying the species whenever possible.
Pay attention to preparation and anisakis
One of the risks associated with eating fish is anisakis, a parasite that can cause gastrointestinal problems and allergic reactions when fish is eaten raw or poorly prepared.
To reduce this risk, it is important to cook the fish well. When consumed raw, marinated or lightly cooked, prior freezing is an essential food safety measure.
This precaution is particularly relevant for pregnant women, young children and more vulnerable people, who should avoid higher-risk preparations.
Therefore, the most balanced choice is to include fish on a regular basis, favoring small species rich in omega-3, such as sardines, mackerel and anchovies, without forgetting the importance of varying and preparing each meal correctly.
