Fatty fish

Fatty fish contain between 5 to 20-30% fat. Since they are mainly captured from the wild, they are of different ages and from different environment, so possibly consuming different diets, therefore have a variable composition.

 Farmed salmon is fatty, whereas wild salmon in general contains less fat, in part because wild salmon have a limited food intake on their journey from the open sea to the rivers for spawning.

In fatty fish the fat is contained in the muscle-fillet, while in lean fish the fat is located primarily in the liver.

Salmon

Fatty fish are rich source of protein, niacin, vitamin B6, iodine and selenium. They are a source of iron, zinc, thiamine, and riboflavin and an extremely rich source of vitamin B12.

Fatty fish contain high levels of unsaturated fatty acids which are susceptible to attack by atmospheric oxygen leading to rancidity. Hence, fatty fish such as sardines always have a shorter storage life than lean fish. Fatty fish offers potential health benefits from omega-3 fatty acids.

Benefits Associated with Nutrients from Seafood

Benefits Associated with Nutrients from Seafood
The high nutritional quality of seafood makes it an important component of a healthy diet.

While protein is an important macronutrient in the diet, most American already consumes enough and do not need to increase their intake.

Fats and oil are also part of a healthy diet, but the type and amount of fat can be important - for example, with regard to cardiovascular disease.

Many Americans consume greater than recommended amounts of saturated fat as well as cholesterol from high-fat protein foods such as beef and pork.

Many seafood selections are lower in total and saturated fats and cholesterol than some more frequently selected anima protein foods such as fatty cuts of beef, pork and poultry and are equivalent in amount of fat to some leaner cuts of meat.

Since it is lower in saturated fats however by substituting seafood more often for other animal foods, consumers can decrease their overall intake of both total and saturated fats while retaining the nutritional quality of their protein food choices.

Seafood is also a primary source of EPA and DHA in the American diet.

The contribution of the nutrients to improving health and reducing risk for certain chronic disease in adult has not been completely elucidated.

There is evidence however, to suggest there are benefits to the developing infants such as increasing length of gestation, improved visual acuity and improve cognitive development.

In addition, there is evidence to support an overall benefit to the general population for reduced risk of heart disease among those who eat seafood compared to those who do not, and there may be benefits from consuming EPA and DHA for adults at risk for coronary heart disease.
