Mackerel is a name for some species of oily cold water fish. This type of fish generally lives far in the high seas, although some species can also be found in the bay waters not far from the beach. Mackerel has received widespread attention thanks to the content of omega-3 fatty acids. The AHA (American Heart Association) recommends us to eat fish which is rich in omega-3 at least twice a week to maintain heart health.
Four Benefits of Frozen Mackerel
You can eat frozen mackerel since the fresh one is more expensive. The nutrition is still the same as the fresh mackerel. Here are some of the nutritional content and benefits of frozen mackerel for health.
- Relieve hypertension
The study, published in the journal Atherosclerosis in 1985 and 1986, found that mackerel fish can benefit various indicators of heart health. In the study showed that people who suffer from mild hypertension experience a decrease in blood pressure after regularly consuming mackerel fish for eight months.
- Lowers bad cholesterol
One indication of our heart health can be seen from the cholesterol content in the blood. The good news is that mackerel fish can be beneficial for those with high cholesterol. Research in 1985 showed that there was a positive relationship between consumption of mackerel fish and a decrease in bad cholesterol. In the study, it revealed that the participants who consumed mackerel fish routinely experienced a decrease in triglycerides by 28 percent. As for bad cholesterol level dropped by 14 percent. In contrast, good cholesterol level increased by 12 percent.
- Good for bones
One of the nutrients needed to support bone strength is vitamin D. People rarely experience vitamin D deficiency because these vitamins can easily be obtained from sunlight, especially in the morning. However, people who have minimal activity outside the home can experience a vitamin D deficit if they are not equipped with food sources. Mackerel provides vitamin D which can be an alternative source for those in need.
- Nutrition for the brain.
The benefits of omega-3 fatty acids are not only for heart health but also can improve brain intelligence. A pregnant woman is highly recommended to consume fish rich in omega-3 as well as mackerel. Fresh mackerel contains about 2.2 grams of omega-3 fatty acids in 3 ounces.
Tips to Choose Frozen Mackerel
Buying fish in a fresh state is the right choice. But there are several types of fish that cannot be obtained fresh and are only available frozen like frozen mackerel. If you want to buy the frozen one, see the tips below
- See the label
Before buying frozen mackerel, pay attention to the label attached to the fish packaging. This label usually contains a code or description of where the fish is obtained. Are they caught in a legal or illegal way?
- See the origin of the fish area
Pay attention to where the fish comes from. Usually, there is information on the sticker attached to the packaging. The description of the water area is very important because you have to know where the fish comes from. Never buy fish from polluted sea waters. America is a country whose government is strict about the safety of food in circulation.
- Pay attention to the process of freezing fish
Frozen mackerel is processed in two ways, which are frozen directly on the ship when they are newly captured or frozen after arriving on land. There is a code that can be identified that is the FAS code which means it is frozen directly on the ship and IQF which means fish are frozen on land. The quality of frozen fish will be reduced if the fish is repeatedly frozen and then thawed and then frozen again.
