What are the disadvantages of eating frozen meat often?

Frozen food is very common in our daily diet. Usually, many people buy frozen meat, mainly because it takes a long time, especially those who are busy at ordinary times and don't have much time to buy food often may eat more frozen meat. Although it is convenient to eat frozen meat, it is not good and harmful to human body.

1, accelerated aging

The low temperature in the freezer can prevent bacteria from multiplying, but it can't completely prevent the oxidation of fat and protein, so it can't completely prevent the deterioration of meat quality.

Due to the oxidation reaction, the color of lean meat frozen for a long time will gradually change from red to brown, and the fat will gradually turn yellow, which will not only make the flavor worse, but also produce fat oxidation products that accelerate human aging.

2, increase the risk of cancer

Expired frozen pork contains many bacteria, even some tiny parasites, which are harmful to health. Long-term consumption of expired frozen pork will lead to the decline of people's own immunity and even increase the risk of cancer.

3, leading to diarrhea

According to clinical statistics, the number of patients with inflammatory bowel disease is increasing year by year, and about 30% of them say that food has been stored in the refrigerator for too long.

4, the loss of vitamins is large.

Frozen meat not only tastes bad, but also decomposes essential amino acids if protein is oxidized. The longer the freezing time, the greater the loss of vitamins, especially B vitamins.

5, 4 meat taboo

(1) Never eat dead pork.

Sick pork often carries pathogenic microorganisms, which are easily contaminated by harmful microorganisms and may even have unknown poisons, so it is difficult to kill germs in home cooking.

Going to regular supermarkets and farmers' markets to buy meat that is obviously lower than the market price can avoid buying sick and dead meat to the maximum extent.

(2) Don't eat overcooked meat.

At the temperature of 200 ~ 300℃, amino acids, creatine, sugar and harmless compounds in meat food will react chemically to form aromatic amino groups. Aromatic amino groups contain 12 compounds, 9 of which are carcinogenic.

(3) Do not eat high-temperature fried bacon.

Bacon contains nitrate, which will produce carcinogenic substance nitrosopyridine after frying. Therefore, when eating salted fish, bacon, sausage, ham and other foods, avoid frying.

(4) Avoid freezing after thawing.

When thawing meat, it is best to take it out of the frozen layer in advance and put it in the freezer overnight. Naturally, you will lose the least flavor and gravy, but avoid secondary freezing after thawing. Repeated freezing and thawing will make the reproduction of bacteria more crazy.

6. The correct way to eat frozen meat

1, pay attention before freezing meat.

Before putting the unfinished meat in the refrigerator, don't put the meat directly in the bag, but cut the meat into small pieces first, so that you can take the right amount when you take the meat.

In this way, the problem that meat needs to be repeatedly refrigerated and thawed is avoided, and the breeding of bacteria is reduced.

2. Pay attention to the method of thawing

Compared with hot fresh meat, the hygienic conditions of frozen meat are better. But it is harmful to health, mainly due to improper thawing method.

Some improper thawing methods will destroy the moisture, juice and taste of meat. Therefore, in order to better preserve the taste and nutrition of meat, we must master the correct thawing method.

Many people are used to thawing frozen meat with hot water. Actually, this is not right. In the process of thawing meat with hot water, vitamins and nitrogen-containing substances will be dissolved, which will destroy the taste and nutrition of meat. The correct method should choose running water to brew frozen meat to avoid breeding pathogenic substances.

2 If some frozen meat needs to be thawed in time, you may wish to use the "power" of the microwave oven. But before putting it in the microwave oven, you need to put the meat in the cold room of the fresh-keeping room of the refrigerator and let it thaw slowly.

3. Learn the correct way to eat meat.

When eating frozen meat, it is best not to burn or roast it at high temperature. The combination of decomposed fat and protein will produce substances harmful to health. If you really want to eat barbecue, it is a good choice to add some fresh green leafy vegetables.

Among them, choosing stewed meat is an excellent way to eat for health. But the stew should not be overcooked or rotted.
