The unfinished meal left over from the night before, commonly known as overnight meal, has always been popular with everyone.

One is that it is convenient to eat, and the other is that it is more delicious. However, such an "overnight meal" is an invisible health killer.

Overnight meals are most likely to produce nitrite, which can cause poisoning.

Although the overnight meal may have only been stored for one night, it has been stored for a long time.

Microorganisms in the air sneak into the food and produce reductase that can convert nitrate into nitrite.

The reason why this kind of nitrite can poison or even kill people after taking only a slight dose is because it can convert normal hemoglobin in the blood into methemoglobin that cannot transport oxygen, which is naturally extremely harmful to the human body.

In addition, eating overnight meals for a long time may increase the risk of gastric cancer.

The nitrite produced in overnight meals reacts with the decomposed protein products contained in the food in an acidic environment to produce carcinogens.

If you eat overnight meals every meal, it cannot be denied that you will be much more likely to suffer from gastric cancer than other people.

Overnight meals can also breed many bacteria that are invisible to the naked eye, such as the most common rancidity bacteria.

This bacteria loves nutritious meals and can release acidic gases that increase appetite, making people fall in love with the taste without even realizing it.

When people eat overnight meals contaminated by bacteria, they can easily cause gastrointestinal diseases and make people feel uncomfortable.

In summary, everyone should try to eat freshly baked meals.

If you want to save leftovers, you can put them in a clean crisper immediately after cooking. Wait until the food is not so hot, then cover it and put it in the refrigerator.
