Summer is a rich season, and all the hotels have come up with vigorous recipes, but there are still some food. Please count it with me.

The so-called seafood, as its name implies, is the supply of fresh marine animals. Seafood has always been people's favorite food. It is rich in protein, low in cholesterol, and has a wide variety, which is more nutritious and superior than meat. There are many seafood, such as oysters, lobsters, sea urchins, sea cucumbers, fish eggs and shrimp eggs. Because they are rich in nutrients such as zinc and protein, they all have the function of strengthening yang and essence.

Four methods of folk seafood:

Cooked food method: generally, there are methods such as boiling, steaming, stewing, frying and frying. Used to cook fish and shrimp into various dishes. Fresh ingredients are often steamed or stewed with pickles.

Raw food method: use live river shrimp, wash it and soak it in wine, sugar and Jiang Mo for a while, then you can eat it raw, commonly known as "drunken shrimp"; Oyster meat is also eaten raw, dipped in some sauce, vinegar, Jiang Mo, etc., and it tastes delicious.

Dry wax method: if fresh yellow croaker is cut open and dried, it is a famous "white fish" with delicious taste; Or cuttlefish (commonly known as "squid") is cut and dried in the sea, which is called "pickling". This kind of dried seafood can not only be preserved for a long time, but also has a unique flavor.

Marinating method: make seafood with salt or distiller's grains and put it in a jar as a perennial dish. If the whole crab is marinated for a few days, it can be eaten.

Although seafood is rich in nutrition, it is not advisable to eat more. Affected by marine pollution, seafood often contains toxins and harmful substances. Excessive consumption can easily lead to spleen and stomach damage and cause stomach problems. If eaten improperly, food poisoning will occur in severe cases. So eat seafood in moderation, usually once a week.

The effective way to reduce the use of seafood is to make the variety of food more diversified and make your variety as rich as possible, which is to disperse and reduce risks. In addition, the diversification of ingredients can also promote the balanced absorption of nutrients, which is also good for the human body.

Get close to organic food

According to planting management and quality certification, it can be divided into four categories: ordinary, pollution-free, green food and vegetables and organic vegetables. Whether it is a certain type of vegetable depends on whether there is a corresponding product quality certification label. Pollution-free vegetables: promise that pesticides will not exceed the standard.

Green food: does not contain any medium or high toxic substances. Organic vegetables: the standard is the highest, and chemical fertilizers, pesticides, production regulators, feed additives, genetically engineered organisms and their products are not used in planting.

At the same time, people should eat less of these fish. The French public health department also pointed out that breastfeeding women and babies under 30 months should not eat swordfish, marlin and other marine fish. When seawater is polluted, pollutants will enter marine animals and plants, gradually accumulate, and gradually transfer through the biological chain, so that the concentration of pollutants in organisms will increase step by step, which is called biological accumulation. Through biological enrichment, the concentration of carnivorous fish at the top of the food chain in water is as high as hundreds or even hundreds of thousands of times. For example, when the concentration of mercury in seawater is 0.000 1ppm, the mercury content in plankton can reach 0.00 1 to 0.002ppm, small fish can reach 0.2-0.5ppm, and big fish can reach 1 to 5ppm. The mercury content of big fish is 654.38+0 to 50,000 times higher than that of seawater. The polluted marine fish not only contains mercury, but also contains heavy metals such as lead and cadmium.

Four principles to reduce the safety of edible seafood

1. Try to be eat small fish. Large carnivorous fish are at a higher stage in the food chain. They are rich in pollutants, such as tuna, sharks, swordfish, sardines, swordfish, yellow croaker, giant clams, mullet roe and all canned fish.

2. Don't eat or eat less fish head, skin, grease, viscera, fish eggs, shark's fin and fish eyes. When cooking fish, clean up the black film in the belly of the fish. These are places where pollutants are easy to accumulate.

3. Eat moderately.

4. Eat seafood with broccoli, tomatoes, mushrooms, apples, etc. Conducive to the discharge of pollutants.
