Salmon, also called salmon or salmon, is one of the commonly used fish ingredients in western food. There are different kinds of salmon in consumer markets in different countries. Norwegian salmon is mainly Atlantic salmon, Finnish salmon is mainly red-fleshed rainbow trout, and American salmon is mainly Alaska salmon. Salmon generally refers to salmon belonging to the family Salmonidae, and there are many kinds, such as salmon and humpback salmon produced in northeast China.

Nutritional value of salmon

Salmon is rich in protein, vitamins A, B, E, zinc, selenium, copper, manganese and other mineral forms related to immune function, and has very high nutritional value. Salmon is also rich in unsaturated fatty acids, which can improve the activity of brain cells and high density lipoprotein cholesterol, thus preventing and treating cardiovascular diseases. The ratio of vitamin E to polyunsaturated fatty acids in salmon is as high as 0.73, which shows its high nutritional value and balanced nutritional distribution.

A Swedish scientist has confirmed that women who eat salmon once a week are much less likely to develop kidney cancer than others. If you eat salmon regularly, the risk of kidney cancer is 74% lower than that of people who don't eat salmon. Omega-3 unsaturated fatty acids extracted from salmon can eliminate active biological substances that damage skin collagen and skin moisturizing factors, and play an anti-wrinkle role. Omega-3 unsaturated fatty acids contained in salmon can reduce the triglyceride content in human blood, increase high density lipoprotein cholesterol, enhance blood vessel elasticity, effectively reduce blood lipid and blood cholesterol, and have a good effect on the prevention and treatment of cardiovascular diseases and Alzheimer's Harmo's disease.

Health-preserving efficacy of salmon

1, rich in protein Like other fish, salmon is also rich in protein, and it is higher than other fish, so eating more salmon can maintain the balance of potassium and sodium; Eliminate edema. Because it is rich in high protein, it can also improve immunity. Because protein is rich, it helps to protect the elasticity of blood vessels, so it can lower blood pressure. Hemoglobin is also a kind of protein, so it can buffer anemia and is beneficial to growth and development.

2. Rich in copper, copper is an indispensable mineral for human health, which is related to the color of our hair. If copper is lacking, juvenile gray hair will appear. Copper has an important influence on the development and function of internal organs such as blood, central nervous system and immune system, skin and bone tissue, brain, liver and heart. Lack of copper can also lead to anemia, so salmon supplementation is one of the better ways to ingest copper.

3. Prevent stroke. Because salmon can live in the deep sea, there is an unsaturated fatty acid in its blood, which can remove excessive saturated fatty acid in blood, reduce blood lipid, strengthen blood circulation, reduce the damage of lipid toxins to blood vessel wall and maintain the elasticity of blood vessel wall, so it can effectively prevent stroke.

4. Other functions. Because salmon contains DHA, it is called the protector of the brain, so it has the function of enhancing brain function and preventing Alzheimer's disease, and can be used for adjuvant treatment and prevention of Parkinson's disease, stroke, vision loss and other diseases. Salmon can also effectively prevent diabetes.
