alert!Don't heat these 6 kinds of food again twice, it is best to throw away it after eating!

In daily life, we will inevitably have leftovers that can't be eaten. For these leftovers, they usually eat them when they eat them again.

But do you know, some foods cannot be heated twice, it is best to throw it away! There is no benefit of blind saving, and many hidden dangers can be buried for the body! Which foods cannot be heated twice? How should we handle leftovers?

It is best not to heat these foods in the second time

1. Bacteria food

When it comes to bacteria, the first thing that thinks of mushrooms is mushroom. After the mushrooms are cooked at high temperature, a large amount of nitrate will be produced. It is stored in the low temperature in the refrigerator. If you continue to eat it the next day Increase. Mushrooms that are often heated for the second time may cause symptoms such as abdominal pain and diarrhea. Long -term eating will increase the probability of suffering from the digestive system tumor. Lose.

Second, seafood food

Seafood foods such as shrimp, crabs, and flower armor are not suitable for secondary heating. If the seafood that is not eaten for too long, it is easy to breed bacteria, produce toxins, increase the burden of detoxification of the liver. It is best to make it now.

Third, spinach

The oxalic acid content of spinach is high, and it needs to be eaten after watering. In addition, spinach also contains a large amount of nitrate. If it is heated twice, spinach will be converted into nitrite because it is reappeared, which is harmful to the human body.

Fourth, milk

Milk cannot be heated repeatedly, and the milk will deteriorate after a long time, which will breed bacteria and easily cause diarrhea. In addition, repeated heating milk will degenerate protein in milk and lead to lack of nutrition. Therefore, the normal milk is cooked and given to the child to drink. Do not heat it repeatedly, which can achieve the role of supplementing nutrition.

Five, Tremella Soup

Because Tremella contains more nitrate, cooked Tremella soup, if it is placed for too long, nitrate will be decomposed and restored to nitrite. Nitrite can cause hemoglobin in the blood to lose the ability to carry oxygen, thereby destroying the normal hematopoietic function of the human body and affecting health. Therefore, it is best to make it now, do not overnight.

Six, Hearts with Eggs

The hearty eggs mainly refer to the eggs that are not cooked, so the cooked eggs cannot completely kill the Salmonella in the eggs. If another night is placed, the chance of bacterial reproduction and toxin is added. Even if it is cooked for the second time, it is best to avoid eating.

Occasionally, eating a small amount of eggs may not cause obvious harm to human health. However, if there is excessive consumption or frequent eaten eggs, it may cause gastroenteritis, symptoms such as abdominal pain, diarrhea, nausea, and food poisoning may occur in severe cases.

It is best to eat the eggs, so that all the bacteria inside can be eliminated. The cooked eggs are stored at low temperature and sealing. Generally, there are no problems with 48 hours.

How to treat leftovers at home correctly?

1. Treat the leftovers, the processing attitude must be "rigorous"

The fourth point of "Five Points of Food Safety" proposed by the World Health Organization is clearly recommended in the fourth point of "keeping the safety of food": cooked food must not be stored at room temperature for more than 2 hours, it should be refrigerated in time (preferably below 5 ° C), do not be in the do not be in The refrigerator is stored for more than 3 days, and the number of leftovers should not be heated more than once.

Second, the remaining foods should be smart, it is best to "only leave the meat without the vegetables"

Compared with meat foods, vegetables will produce more nitrite during the storage process, and there will be a large part of nutritional loss (vitamin C, etc.). Taken together, it is recommended that everyone "really left, try to leave as left without vegetables."

In addition, cold dishes are not recommended. Cool dishes are generally not heated, and it is easier to breed harmful substances such as bacteria, which can induce food poisoning such as diarrhea and abdominal pain.

Third, the storage of leftovers should be "scientific"

In order to ensure the "hygiene and safety" of leftovers and leftovers, it is recommended to avoid "unnecessary operations" for them.

(1) Reduce chopsticks such as chopsticks and other devices. The material and reliable fresh -keeping box are installed and leftovers to ensure its sealing.

(2) During the storage process of the leftovers, they should be placed in the "low -temperature area of ​​the refrigerator". Eat it as soon as possible to avoid a large amount of breeding of microorganisms such as bacteria.

(3) It is worth noting that leftovers need to be "classified packaging + store" to avoid cross -pollution and skewers.

Fourth, leftovers must be "hot" before eating

Although leftovers can be eaten, they must be "completely heated" before eating. In other words, the leftovers should be heated to 100 ° C, and at least 5 minutes should be kept boiling.

5. How much to eat, how hot, do not "repeat heating"

In order to reduce the risk of microorganisms and avoid food poisoning incidents, it is not recommended to heal repeatedly for leftovers and leftovers. How much can I eat and how hot each time, the rest of the food continues to store it in the refrigerator and eat it quickly.
