foods that should not be reheated

Eat food, but do you know that reheating food can be a serious health risk

Are you accustomed to eating fresh food or stale food?

If you are accustomed to eating stale food, have you ever wondered if it will have any adverse effect on your body at all?

In this age of modernity, it is not a matter of heating food at the same time.

However, it is important to know how much damage this can do to your body.

This is because once the food is cooked and reheated, the nutritional value of the food is often lost.

Even the protein and nitrates in the food are broken down, which makes our favorite food toxic.

Due to which there are various types of problems such as indigestion, vomiting, fever, upset stomach, diarrhea and even cancer.

foods that should not be reheated:

Do not reheating food after cook;

Egg s are a food that should not be eaten hot for the second time

Egg s are called the power house of protein. Again, it contains antioxidants.

However, if the egg is exposed to temperature for the second time after it has been cooked, the proteins in the egg break down, and this breakdown causes bacteria called salmonella to grow.

In addition, the nitrogen in the eggs is oxidized, which increases the risk of cancer.

Therefore, according to nutritionists, it is not right to eat either cooked or fried eggs hot for the second time.

Side effects

Indigestion, fever, abdominal pain and diarrhea.

Rice should not be eaten for the second time or reheated.

According to a study by the UK’s Food Standards Agency, if rice is kept at normal temperatures for more than an hour after cooking, a type of bacteria called Bacillus sirius begins to form.

Reheating the leftover rice does not kill the bacteria.

Rather the bacterial spores continue to reproduce and at one stage can produce enterotoxins that can cause food poisoning.

Side effects

Vomiting and diarrhea.


Since rice is the main food of Bengalis, you can cook it a little before it is time to eat. If this is not possible, you can refrigerate the rice and take it out shortly before eating and return it to normal temperature. And also keep in mind that you should never leave rice in the fridge for more than 1 day.

3.Burning Oil

Oil cannot be used a second time

Many of us leave the remaining oil at the end of cooking or frying for the next meal. When the oil is overheated for frying, the composition of the oil changes and toxic substances are formed in it.

This oil is bad for the heart. This oil is responsible for making bad cholesterol in the blood i.e. atherosclerosis. So avoid eating on the side of the road or on the sidewalk.

Because most of the food on the sidewalk is made with firewood. Besides, you have to give up the habit of cooking with firewood at home.

Side effects

May cause acidity, heartburn, Alzheimer’s disease, Parkinson’s disease, sore throat.

There is also a risk of carcinogenic cancer from the free radicals that are formed when the oil used once is used in cooking again.


Oil is an essential ingredient in cooking anything.

After cooking, the remaining oil can be cooled and stored in an airtight container. Sifting will remove food residue in the oil, which would quickly destroy the oil.
Before re-using burnt oil, note that if the color of the oil becomes darker, thicker than usual, sticky and comparatively more smoky, it cannot be used, it should be discarded.

It is not okay to reheat chicken

From E. coli to Salmonella, various bacteria begin to grow rapidly on chickens. So if the chicken is not cooked or preserved properly, it is dangerous to eat the chicken.

When the chicken meat is reheated, the properties of the protein in the chicken meat change.

The altered properties of proteins combine amino and nitrates in meat to form nitrosamines, which are thought to cause cancer.

Side effects
Digestive problems can even cause cancer.

If there is anything left after eating, keep it in the fridge. You can take it down to normal temperature before eating. And if you have to eat it hot, heat it in the oven for a little longer.

5. Potatoes

Reheating potatoes is bad for your health

If the nutritious potato is kept at room temperature for a long time after cooking, its nutritional value starts to deteriorate. Reheating increases the health risk.

Potatoes are rich in carbohydrates and heat sensitive vitamins, such as vitamin B complex and vitamin C.

Reheating reduces the levels of these vitamins. Again, botulism (a rare type of bacterium) can occur.

When the potatoes are cooked at room temperature for more than 2 hours, the breeding ground for the bacteria becomes effective. There is a risk of food poisoning.

Side effects

Dizziness, sickness, upset stomach, indigestion, respiratory diseases and muscular dystrophy.

6. Spinach

Spinach should not be eaten hot for the second time

Spinach is rich in iron and nitrate.

Reheating cooked spinach breaks down this nitrate into nitrites and other carcinogenic substances.

These compounds cause the presence of methemoglobinemia, which affects the level of oxygen in the body. These nitrites can be converted to nitrosamines.

Side effects

Stomach upset, risk of cancer.


If you have to be reheating food after cook, you have to cool it immediately after cooking.

It should be stored at a temperature below 5 degrees Celsius. This will prevent the conversion of nitrate to nitrosamine.

7. Tea

It is not okay to reheat tea

We drink tea at any time in our daily life.

However, many people reheat tea once it has cooled down, which is very harmful. Because tea contains tannic acid.

Side effects

May cause liver damage.


You can put the tea in the flax by giving up the habit of heating the tea again and again.

8. Mushrooms

Mushrooms should not be eaten a second time or reheated

Usually the fiber and enzymes in mushrooms help in digestion.

It helps to increase the work of beneficial bacteria in the gut.

And helps to increase the absorption of nutrients in the colon.

When the mushrooms are reheated, the proteins in the mushrooms are lost and the nutrients lose their quality.

Side effects

May cause indigestion and heart problems.


It is better to eat mushrooms immediately after cooking.

Cook as much as you can eat. Even if it is kept in the fridge, take it down to normal temperature before eating.

9.Roasted red meat

Roasted red meat should not be eaten a second time.

The second time roasted red meat is heated, the chemical structure of its protein changes in such a way that it can cause problems in our digestion process.

10.Celery, beets and spinach

These 3 vegetables have one common ingredient which is – nitrate. Harmful nitrites can be converted to nitrosamines after heating for the second time. Some of the nitrosamines are known as carcinogenic.

Side effects

Stomach upset, indigestion and even increases the risk of cancer.


Celery, beets and spinach can be kept in the fridge and eaten as per the rules.

And if you have celery and meat in the soup, before heating for the second time, remove the celery and meat and then heat it.

Since health is the root of all happiness, we need to strive to be healthy and functional.
