Is preserved fish nutritious? Does eating often affect your health?

Preserved fish is rich in nutrition. Preserved fish has tender meat, delicious taste and high nutritional value. Protein content is 26.7%, fat content is 30.8%, especially vitamin A content, and phosphorus, calcium, iron and other elements are also high.

Eating preserved fish often causes cancer, because preserved fish contains nitrite. As a food additive, nitrite has a positive effect on improving the quality of meat products, but excessive use will cause nitrite poisoning.

Under the action of microorganisms, nitrite can be converted into nitrosamines in the stomach, which is a strong carcinogen. In addition, nitrogen-containing substances in meat varieties can be transformed into nitrite through amination and nitrification of bacteria.

Fresh fish will produce some nitrite in the traditional pickling process, mainly because microorganisms such as Escherichia coli, Staphylococcus aureus and mold in pickled fish have strong reducing ability, which can reduce nitrate in fish to nitrite.

At the same time, nitrogen-containing substances such as protein in fresh fish decompose to produce amine substances such as trimethylamine, which will further form nitrosamines into nitrite, which is easy to cause cancer to human body.

Eat smoked fish healthily:

1, eat less

Smoked bacon is not only delicious, but also keeps for a long time. In the process of processing and curing, a certain amount of sodium nitrite should be added as a preservative. Sodium nitrite can combine with amines in meat in vivo and in vitro to form dimethylnitrosamine, which is a highly carcinogenic substance.

2. Reasonable side dishes

When eating pickled products, properly match some fresh vegetables rich in vitamin C, such as Chinese cabbage, green pepper, cucumber and spinach. Or eat more fruits rich in vitamin C after meals, such as oranges, oranges, kiwis and apples. It can block the combination of nitrite and amine, and avoid or reduce the harm of carcinogens to human body.

3. Eat more anti-cancer foods.

Some anticancer foods can eliminate nitrosamine carcinogens in food and body, and may also promote the transformation of some precancerous cells into normal cells. Garlic and garlic head contain sulfur-based compounds, allicin and trace element selenium, all of which have strong anti-cancer effects.
