Overnight foods can cause cancer, Vietnamese people 'regret' or keep them

There are two reasons why food becomes toxic. One is because it contains carcinogenic substances, such as nitrites, which cannot be eliminated even by heating. Another reason is bacterial contamination over time.

Below are the foods that are most susceptible to bacterial contamination when left overnight, causing harm to the body if eaten:

Egg

Nutritionists say that if you leave boiled eggs overnight, if you do not store them in the refrigerator but leave them outside, it will create conditions for microorganisms to grow, which is very harmful to the stomach and intestines. Note that with soft-boiled eggs, you should eat them immediately and not leave them for too long.

Soybean products

Soybean products are high in protein and nutrients, providing a rich source of nutrients for microorganisms. Not only that, tofu and soy milk, if left for a long time, can easily become contaminated with Clostridium botulinum - a type of bacteria that can cause paralysis and death.

Seafood

Seafood left overnight such as cooked shrimp, crab, and fish will cause the protein content to denature, causing damage to the liver and kidneys. It is even more dangerous if they are reheated many times.

Mushrooms, wood ear mushrooms

The ideal time to consume mushrooms is the same day, because if left overnight, the complex protein components in this food can be harmful to the digestive system if reheated. In addition, mushrooms and wood ear mushrooms, whether cultivated or grown naturally, contain a lot of nitrate.

If processed mushrooms are left for too long, it can lead to loss of nutrients, nitrates produce toxins, and cause stomach discomfort.

Soup left overnight in a metal pot

Leftover soup left overnight in metal pots such as aluminum, stainless steel, etc. can easily produce toxic substances that are harmful to health.

If you want to save the soup for the next meal, it is best not to add any other spices to the soup or you can put the soup in a ceramic or glass bowl and store it in the refrigerator.

Braised dishes

Braised dishes should not be left overnight, even if they are stored in the refrigerator. Because if left overnight, braised dishes can easily produce mold, causing food poisoning, especially in spring and summer.

Green vegetables

Green vegetables contain very high levels of nitrates. If you don't finish eating them, it's best to throw them away. Never leave them overnight, especially spinach or celery. When nitrates are cooked and left for a long time, they easily turn into nitrites, which are extremely dangerous carcinogens.

Soup

Many families often have the habit of cooking soup to eat gradually over the course of a few days without knowing that if this dish is left overnight, it can easily create harmful precipitates.

Salad

Most salads do not require heat to cook, so they contain higher levels of bacteria than normal. If you leave this dish overnight, even if it is stored in the refrigerator, it will not limit the growth of bacteria and mold, causing intestinal diseases and even poisoning.

Potato

Potatoes are nutritious and healthy food, however, if left overnight and reheated in the microwave, all the beneficial nutrients will disappear, replaced by harmful substances that cause bloating and indigestion.

Rice

Once the rice has been cooked, the spores may still survive. Therefore, leaving rice at room temperature for a long time can cause bacterial spores to multiply, producing harmful substances, making the person who eats it susceptible to vomiting and diarrhea.

In particular, reheating rice cannot remove these harmful substances.

Chicken

The protein content of chicken will change if it is cooled and reheated a second time. This can cause digestive problems for the person eating it. Therefore, you should not leave cooked chicken overnight.
