6 types of food left overnight are harmful to health, even cause cancer

When eating leftovers, many people try to reheat them, but many people have the habit of eating cold food. This causes great risks to health, especially in the summer because just leaving food for 8 hours is enough time for harmful bacteria to grow.

Below are 6 types of food that experts recommend not to leave overnight:

1. Rice

Experts say that rice grains contain many bacterial spores, which can cause food poisoning if not properly preserved. Even after being cooked, the spores still survive and multiply when given the "opportunity".

Therefore, if you continue to leave leftover cold rice at room temperature, it can cause bacterial spores to produce harmful substances that cause vomiting, diarrhea, etc. In particular, in many cases, reheating rice cannot completely remove these toxic substances.

2. Boiled filtered water

According to research, water is best suited for drinking when boiled for 3-5 minutes and consumed within the day. At this time, the content of toxic substances such as nitrite and chloride in the water is lowest. However, if the water continues to boil or is left to cool for too long, the amount of nitrite will increase significantly.

3. Soft-boiled eggs

Soft-boiled eggs left overnight will cause bacteria to grow and multiply more easily than usual, causing bloating, indigestion, etc. On the contrary, if eggs are fully cooked and stored at low temperatures in the refrigerator, they can be stored for 48 hours without any problems.

4. Green leafy vegetables

Typically, leafy greens are highest in nitrates, followed by cucumbers and cauliflower. So if you have a lot of vegetables at once, try to consume leafy greens first.

In addition, experts also recommend that in the summer, if you do not finish eating processed green leafy vegetables, it is best to throw them away and absolutely do not leave them overnight, especially spinach and celery.

The reason is that the nitrate content in these two vegetables is relatively high. After cooking and leaving it for a long time, it will easily turn into nitrite - a substance that causes cancer.cancerdanger.

5. Seafood

If seafood such as shrimp, crab, and cooked fish are left overnight, the protein content will be denatured, causing damage to the liver and kidneys. In case you accidentally buy a lot of seafood but do not finish eating it, you can put it in a bag or box and put it in the freezer, then process it gradually.

6. Mushrooms, wood ear mushrooms

You should eat mushrooms the same day after processing, because if left overnight, the complex protein components in them can be harmful to the digestive system, especially when reheated. In addition, mushrooms and wood ear mushrooms, whether cultivated or naturally grown, contain a lot of nitrate.

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