is approaching the spring year, and the dining tables of every household are beginning to flourish. The guests at home do not hate too many people, but only hate not enough dishes.
After a meal, the refrigerator is also full of leftovers. Eat, worry about the toxic substances in overnight dishes , don’t eat, and feel wasteful.
Are leftovers heated repeatedly really cause cancer?
Regarding the hazards of overnight dishes, what everyone hears most is that it is carcinogenic, because it produces nitrites .
In fact, all plant foods contain nitrite and nitrate. But under normal circumstances, the content is very low, far from causing harm to the human body.
As the freshness decreases, the content of sub- nitrate will increase, but only a little bit, the nitrite content in overnight vegetables is also far below the national safety standards for processed foods. Even if
is heated repeatedly, it just rises a little bit like a pile of wood, so don’t worry too much.
Instead of worrying about nitrite, it is better to worry about deterioration, bacterial pollution and other issues.
But not all leftovers can be heated repeatedly. Meat dishes can be stored for 1 to 2 days, and they must be heated thoroughly before eating. Vegetables are recommended for no more than a day, especially cold dishes.
recommends eating less of these 5 overnight dishes:
leafy green vegetables, compared to meat, fruits and other foods, stem and leaf vegetables contain more nitrite. Don't be afraid if you eat it, because you can't just talk about the toxicity and not the dose. The content of nitrite in overnight leaf green vegetables is just more than other foods, and it is ok to eat occasionally.
Overnight seafood may produce protein degradation products, which may damage the liver and kidney function. Z1z
Tremella mushrooms, cooked Tremella and mushrooms, will also produce nitrite if left for too long.
Soft-boiled eggs , which are half-boiled eggs, are not completely sterilized in the first place, and it is easy to breed bacteria after a long time.
soy milk, it is best to drink it within 4 hours at room temperature, otherwise the number of colonies in it will increase significantly and cause deterioration.
So for the leftovers, it is better to leave meat dishes than vegetables. If you eat it occasionally, let it go.
repeatedly boiled water causes cancer?
The repeatedly boiled water is commonly known as " thousand boiled water ". It is the object of condemnation and criticism from the seven aunts and eight aunts. They all say that it is poisonous. As for the poison, so far it is an unsolved mystery.
The "poison" referred to here is highly likely to be nitrite again, and nitrite is simply a carcinogenic panacea.
There is only one truth: water that is repeatedly boiled does contain nitrite, but the content is very low. Even if it is burned many times, it is still within a safe range. It is a rogue to talk about toxicity without the dose!
Someone once did an experiment to dispel everyone’s doubts:
The content of nitrite in tap water is 0.007 mg/L,
is boiled once: The nitrite content is 0.021 mg/L,
is boiled 20 times, The nitrate content is 0.038 mg/liter. Even if
is burned to 20 times, the nitrite content in the water is far below the national standard of 1 mg/liter.
The repeatedly boiled water is toxic, it is fake, it is not good to drink, it is true!
Rather than being afraid of excessive nitrite intake by Qianboshui, it is better to eat less pickled products and meat products.
So water that is boiled repeatedly is safer than leftovers that are heated repeatedly.
