Some foods, no matter how delicious or expensive, should not be eaten overnight or toxins will build up in the body.
In life, many people want to save food and are afraid of waste, so they often put leftovers in the refrigerator to heat up and eat them the next day. However, some foods are best left unreheated and should be thrown away for health reasons.
Why are reheated leftovers bad for health?
Foods heated overnight are very dangerous to health due to the presence of nitrites. Nitrite is a component of inorganic compounds. If the amount of nitrite ingested by the human body exceeds 0.3-0.5g, it will cause poisoning, which is very dangerous.
In fact, nitrite itself does not do much harm to the body. But after entering the human body, it will combine with hemoglobin to form nitrosamines, which are harmful to the body.
Another question is “Do leftovers cause cancer?” In fact, the most important factor is the body’s absorption of nitrites. Absorption of small amounts is not carcinogenic and will be eliminated by the body.
The nitrite content in vegetables generally does not exceed 20mg/kg. However, nitrite levels can exceed the limit if not fed for more than 3 days. Also, leftovers contain many different kinds of bacteria and viruses, and spoiled food also produces some toxins that will definitely affect your health.
Therefore, some dishes cannot be eaten overnight. As long as it is stored properly, the body will not absorb too much nitrite. However, the following food, it is best to throw away, so as not to hurt the body.
1. Mushrooms

This is a substance that has been identified by the World Health Organization as a carcinogen and possibly harmful to health.
2. Seafood

3. Boiled vegetables
Generally green vegetables have the highest nitrite content, and melons are slightly lower. If it is cooked green vegetables, it is best to eat immediately, do not throw away the excess, save it for the next day. In general, vegetables should be cooked in moderation to avoid excess and food waste.
4. Undercooked food (steak, hard-boiled eggs)
These foods are not suitable for reheating. Since they are not fully cooked, bacteria may remain. The bacteria will multiply after a few hours or a long night, and if you don’t eat it all, it’s best to throw it away.
5. Soymilk
