Reduce the risk of heart attack and stroke

Heart attack and stroke are the two most common causes of death in the world. Meanwhile, fish is considered one of the heart-healthy foods. Many studies show that people who eat fish regularly have a lower risk of heart attack, stroke, and death from heart disease. In a study of more than 40,000 men in the United States, those who regularly ate one or more servings of fish per week had a 15% lower risk of heart disease. Researchers believe fatty fish are even more beneficial for heart health due to their high omega-3 fatty acid content.

Fish contains important nutrients during fetal development

Omega-3 fatty acids are essential for growth and development. The omega-3 fat docosahexaenoic acid (DHA) is especially important for brain and eye development. Therefore, pregnant and breastfeeding women are generally recommended to eat enough omega-3 fatty acids.

However, certain types of fish are high in mercury, which has been linked to problems with brain development. Therefore, pregnant women should only eat fish that are low in mercury, such as salmon and sardines, and no more than 340 grams per week. In addition, pregnant women should also avoid raw and undercooked fish as it may contain microorganisms that can harm the unborn baby.

What is the most nutritious way to eat fish?

While eating fish is healthy, the way you cook it can change its nutritional profile, so it’s important to know which cooking method is best for your health.

Baking method

Baking is a method of applying dry heat to cook foods at high temperatures. However, this method is believed to cause the formation of several harmful compounds called heterocyclic amines (HA) and polycyclic aromatic hydrocarbons (PAH).

These two types of compounds form when muscle tissue from meat or fish is heated to very high temperatures, especially over direct fire. But the risks associated with these compounds are only related to their consumption. lots of red or processed meat. Eating grilled fish is not associated with the same risks.

The baking method can also lead to the formation of compounds known as AGEs. These compounds form naturally in the body as you age, but can also form in muscle foods like meat and fish when they are cooked to high temperatures. High levels of AGEs have been linked to a number of diseases, such as heart disease, diabetes, and Alzheimer’s disease. To reduce exposure to these compounds, avoid direct exposure to fire and try to keep baking times as short as possible to prevent the meat from burning. In addition, applying sauce to fish before grilling is considered the secret to reducing the formation of HA and PAH.

Pan frying and frying method

Pan frying and deep frying are methods of cooking at high temperatures in hot fats. Deep-frying involves submerging foods in a large amount of fat, while deep-frying uses much less fat. During the frying process, the fish will absorb some of the fat, increasing the calorie content and changing the type of fat that the fish has.

Frying fish with oil, such as vegetable oil, which is high in omega-6 fatty acids can increase inflammation-causing omega-6 levels. This has been shown to occur to a greater extent when fish is deep-fried rather than pan-fried, due to the greater amount of oil used. In general, lean fish also tend to absorb more oil than fatty fish.

The high heat during frying also damages the healthy omega-3 fatty acids in fish more than other cooking methods. In fact, one study found that frying tuna reduced beneficial omega-3 fatty acids by 70–85%. However, it appears that these effects may vary depending on the type of fish you fry. Other studies have found that some fish, such as herring, may still contain beneficial amounts of omega-3s after frying.

In general, pan-frying is considered healthier than deep-frying because less fat is needed. In addition, it is best to choose an oil that is stable at high temperatures such as olive oil as one of the healthier options.

Boiling and Steaming Methods

Boiling and steaming are cooking methods that use water or other liquids to cook foods. Boiling is the method of cooking food submerged in water or other liquids such as milk, wine, etc. While steaming is usually done in a pot or specially designed appliance to use hot, evaporating water as nine foods.

Neither of these methods will add any fat to the fish, so the fish after processing will add no calories nor change the fat previously present in the fish.

Boiling and steaming also cook fish at slightly lower temperatures than other methods, which preserves nutrients and is thought to minimize the formation of harmful chemicals like HA and PAHs.
