Tuna fish (Euthynnus affinis) is a type of marine fish from the Scombridae tribe. Mainly exploring in shallow waters near the coast in the Indo-West Pacific region, mackerel is one of the most important types of catch for fishermen. In international trade it is known as kawakawa, little tuna, mackerel tuna, or false albacore.
Medium sized fish; the maximum length is about 100 cm FL (fork length), but generally only about 60 cm. Back is dark metallic blue, with an intricate slanted streak pattern running from the middle of the first dorsal fin to the back; the sides and belly are silvery white, with characteristic dark spots between the pectoral and pelvic fins, which are not always present. No scales, except in the corselet and lateral line.
Here are some of the benefits of consuming tuna for your health:
1. Meet protein needs
You can use cobs as an alternative source of cheap animal protein to complete the daily requirement (RDA).The protein content in tuna can help meet your daily nutritional needs. Protein is important for building new cells and tissues in the body to replace damaged ones. In addition, protein can help repair damaged cells, boost the immune system, and strengthen bones and muscles. Protein also functions to maintain healthy hair, skin, nails, and body muscles.
Protein deficiency is a fairly rare condition.
But if you experience it, the symptoms of this nutritional deficiency can make you sick more easily, the body continues to feel weak, and it is slower to heal from wounds.
If the body lacks protein, you are at risk for low immunity, wounds on the body take longer to heal, and the body often feels tired.
2. Help lose weight
If you are on a diet program, you can benefit from weight loss from tuna.Tuna is a low-calorie food, which only contains 109 calories per 100 gram portion. Thanks to the high protein content of tuna, this fish, which is still a relative with skipjack and tuna, can be used as a daily diet menu. Eating a high-protein diet can lower ghrelin levels. Ghrelin is a hormone that is responsible for stimulating hunger so that it triggers your cravings for foods containing carbohydrates.
Decreased levels of ghrelin in the body can help reduce appetite and prevent excessive food cravings.Protein also slows gastric emptying which makes you feel full longer.
3. Maintain the body's electrolyte levels
Additional sodium intake from tuna provides good benefits for maintaining fluid balance in the body.Sodium also plays an important role in maintaining normal nerve and muscle function.The body obtains sodium through daily food and drink. Most of the sodium in the body is stored in the blood and lymph fluid.
To stay consistent, the kidneys are in charge of maintaining sodium levels by removing excess urine and sweat.
However, when the amount of intake and output is not balanced, the total supply of sodium in the body is affected. Eating tuna that contains sodium can help you avoid the problem of hyponatremia, aka low sodium levels. When sodium in the body is low, you are prone to dehydration, vomiting, and diarrhea.
4. Improves thyroid gland health
Mackerel also has other benefits, namely maintaining the health of your thyroid gland. The thyroid gland in the neck is responsible for regulating metabolism, producing hormones, and maintaining the body's energy levels.
If the thyroid gland is disturbed, you are at risk of experiencing symptoms in the form of drastic weight changes, changes in bowel movements, and can even interfere with your sexual abilities.
Not only that, tuna meat contains selenium which can help maintain a healthy thyroid gland.
5. Helps improve brain function
The next benefit of tuna is to maintain brain function. Tuna has many nutrients that are important for the brain, such as omega-3 fatty acids and niacin. Niacin is a mineral that can reduce the risk of Alzheimer's disease and dementia due to aging. Meanwhile, omega-3 fatty acids can improve brain function and can prevent mental health problems, such as depress
6. Rich in antioxidants
Antioxidants are compounds that can neutralize harmful free radicals in the body. The buildup of free radicals in the body can damage cells and pose a risk of many diseases, such as cancer. Eating foods that are high in antioxidants is very good for preventing the development of conditions such as heart disease, diabetes, cancer and certain autoimmune disorders. Well, according to a study published in the World Journal of Biological Chemistry, tuna contains high selenoneine which is one of the antioxidants.
7. Reduce inflammation
Inflammation is actually a normal body response that occurs when the immune system works against viruses, bacteria, infections and diseases. Usually, the inflammation will go away on its own as the disease heals.
However, if inflammation persists for a long time, it may be due to an increased risk of certain diseases, such as heart disease and cancer.
The benefit of fish that contain omega-3 fatty acids, such as tuna and tuna, is to help speed up the healing process of inflammation or reduce it altogether.
It also has the potential to reduce the risk of disease.
The reason, omega-3 fatty acids are also at the same time a strong anti-inflammatory.
There are many studies looking at the benefits of fish oil high in omega-3s in reducing the risk of developing autoimmune diseases, such as Crohn's disease, lupus, rheumatoid arthritis (rheumatism), and psoriasis.
