8 foods that should not be left overnight

(Baonghean.vn) - In family meals, uneaten food is often left for the next day. However, some types of food left overnight can cause unpredictable harm to health.

Seafood

Seafood is at the top of the list of foods.should not be left overnight because after one night, the protein in seafood will decompose, if using these foods can damage liver or kidney function.

Leaving seafood overnight is also susceptible to bacterial attack. During the cooking process, some types of bacteria in seafood cannot be completely eliminated at high temperatures. If cooled in the freezer, bacteria will be able to regenerate naturally or self-regenerate. Therefore, eating seafood left in the refrigerator overnight is unsafe, and can easily cause diarrhea, poisoning, and vomiting.

Mushroom

Mushrooms are used in many dishes. Mushrooms, besides having a large amount of water, also have a high amount of salt, especially snow fungus. If left overnight, the nutrients are lost, and the amount of nitrate salt can decompose and produce toxins.

Even wood ear mushrooms, which can be stored for a long time if dried, once cooked, you need to use them up within the day.

Soy products

Tofu and soy products contain relatively high water content, protein content and other nutrients are also very rich, which is a rich source of nutrition for microorganisms.

If tofu is left for a long time, it can easily produce many dangerous pathogens, such as clostridium botulium bacteria. This bacteria has a poison many times stronger than potassium cyanide.

This toxin will be destroyed after a few minutes at temperatures above 100 degrees Celsius, but if not heated to such temperatures it will become extremely dangerous. Therefore, it is best not to keep soy products for the second meal.

Chicken eggs

Nutritionists say that if boiled eggs are left overnight and not stored in the refrigerator, but left outside at temperatures of 10 degrees Celsius or higher, they will create conditions for microorganisms to grow, which when eaten will be very harmful to the stomach and intestines.

Therefore, you should only reuse boiled eggs if the first time you boiled them thoroughly and then boil them again before eating. Note that it is best not to eat soft-boiled eggs.

Vegetables and soups

Because the nitrate content in green vegetables is quite high, if cooked and left for too long, the bacteria will decompose, the nitrate will turn into nitrite - a carcinogen, even if you reheat it, it cannot be removed. Therefore, you should not eat vegetables left overnight.

The best way to preserve soup longer is to not add spices such as salt, MSG, etc. to the soup when cooking. After cooking, use a clean spoon to scoop it into a separate bowl to eat during the day. Put the rest in a clay pot or glass pot and put it in the refrigerator.

Because leftover soup left in aluminum or stainless steel pots for a long time will have chemical reactions, so it is best to use glass or ceramic containers to preserve soup.

Mixed salad

Salad dressings contain many ingredients such as mayonnaise, vinegar, dried fruit… Even if you keep it in the refrigerator for the next day, the salads can still get moldy and spoil.

Salads are usually made from fresh vegetables, which still contain many bacteria that cannot be completely removed even after thorough washing. Combined with the substances in mayonnaise, it will be a "feast" for microorganisms to grow. These bacteria can easily cause intestinal diseases and even poisoning.

Potato

Potatoes are actually a healthy food when boiled with the skin on. However, if you reheat potatoes in the microwave, all the beneficial nutrients will disappear, and instead, harmful substances will appear for the human body.

Grilled food

Grilled food not only loses its characteristic flavor, grilled food left overnight is also not good for health. Specifically, when put in the refrigerator, the dish will be attacked by many bacteria and molds that live in low temperature environments.

Green tea

Morning is the start of a new day, so you should brew a new pot of green tea and only enjoy it during the day. Do not drink green tea overnight, because if left overnight, all the vitamins, proteins and other beneficial nutrients will be lost…

Not only that, green tea also turns discolored, and the vitamins B and C in it are also decomposed. In addition, green tea left overnight also produces many harmful bacteria and fungi, so drinking leftover green tea from the previous day is very harmful to your health.
