Nutritional value of fish and health benefits, Fish is not only delicious, but also has a high nutritional value. It is rich in protein and other important nutrients. In 100 grams of fish, it contains one-third of the protein that adults need every day. Moreover, the protein in the fish is more easily digested and absorbed by the human body than the meat of other poultry.

Fish nutrition Fish also contains free amino acids, small molecular compounds, rich vitamin B12 and iodine that can be quickly absorbed by the body. Vitamin B12 is an essential nutrient for nervous system health, and iodine is an important element in maintaining thyroid function.

The value of fish oil Fish with a Lot of fat is generally darker in color and contains twice as much calorie as oil with less fat and white meat. In recent years, studies have found that eating fish regularly can prevent heart disease and stroke. The reason may be that fish oil is different from meat oil, mainly unsaturated fat, which is not so easy to produce cholesterol. Therefore, people who eat more oily fish a week have a lower incidence of stroke and heart disease.

Precautions for eating Fish Excessive intake of fish oil (more than 10% of the total calories that should be ingested) is also harmful to the body. Because the unsaturated fat in fish oil is easily turned into a carcinogenic free radical by oxidation, it has a bad effect on the human 1/6

body.

Put the fish on the table quickly.

To be good for the heart, nutritionists recommend eating fish at least twice a week. Fresh fish or unprocessed frozen fish are the best choice. Fat-containing cold-water fish (such as salmon, Atlantic salmon, halibut, herring) contain more Omega3 fatty acids than other fish, making it the best choice for heart health. But avoid choosing fried foods coated with cream batter, such as fried fish sticks.

Omega 3 fatty acids can also be found in foods such as green leafy vegetables, soybeans and nuts, but at a lower level.

If you can't eat it right away, you should also raise it with water until it is slaughtered and cleaned before cooking. If it cannot be maintained, it should be cut and stored in a refrigerator at 0 to 5 ° C and consumed in one or two days.

2. Vulnerable to pollution Shellfish (such as sputum and sputum) are water-filtered animals, filtering up to 90 liters of water per day. If the water quality it survives is contaminated, the risk will be higher than that of fish, and the concentration of pollutants will be higher than in water because heavy metals and bacteria in the water will accumulate in their tissues. Once eaten into the body, it will accumulate in the human body and will not be easily discharged. So don't buy shellfish caught in polluted waters, and don't take shellfish from 4/6
