When the food made at home does not run out, it is usually stored in the refrigerator and then reheated when the next meal time comes. But did you know that there are certain types of food that should not be reheated because they can be harmful to the body? Know the following types of foods that should not be heated:
1. Potato
Those who have replaced rice with potatoes, they will probably serve this food three or two times a day. If leftover lunch potatoes, for example, are not stored properly and then reheated for dinner, they can lead to poisoning. If potato dishes are allowed to cool to room temperature – especially if they are wrapped in aluminum foil, they can become a breeding ground for the bacterium Clostridium botulinum. Reheating potatoes is not always effective at killing these bacteria. As a result, bacteria will enter the digestive tract and become toxic. The best way of consumption is of course to always cook fresh potatoes before eating and finish them immediately. But, if there are leftovers, don't wait for it to cool to store. Put it in the fridge while it's still warm enough. If it must be reheated, use a low heat and a frying pan – don't heat it in the microwave.
2. Chicken
Chicken meat contains more protein, than red meat. If reheated, this protein will break down and be difficult to digest, which can then cause an upset stomach. Try not to heat dishes from processed chicken over and over again. Leftover fried chicken can be cut into pieces for a salad mix or bread filling, no need to re-fried to eat again. If it must be heated, preferably on the stove and not in the microwave – so the heat spreads evenly and doesn't leave any bacteria that might develop when food cools to room temperature. Processed chicken must be cooked and heated at a minimum temperature of 74⁰C so that bacteria are killed, and all parts of the meat are cooked and hot evenly.
3. Spinach
This one vegetable is easy to get and the price is affordable. This is why processed spinach is one of the most consumed types of food in Indonesia. Spinach contains a lot of nitrate which if reheated will turn into nitrite which is carcinogenic and has the potential to cause cancer. If you are cooking spinach, measure the amount so that it can be used up in one serving. Spinach and other leafy vegetables are best cooked fresh before mealtime.
4. Rice
As a staple food in Indonesia, rice will almost certainly be on the table and is generally cooked once for two to three meals. Leftover rice is also often processed into fried rice. Is this actually safe for health? The problem with rice is the same as with potatoes; more of a storage problem than reheating. Rice that is left at room temperature will grow spores which can cause diarrhea and vomiting. Heating rice will not kill the spores that have already multiplied in it. So, frying leftover rice is actually safe. Origin, the rice is not left in an open state when not eaten. It is highly recommended to store it in a closed container.
5. Eggs
Just like chicken, eggs are also rich in protein. If heated, the protein will break and break down. In addition, heated eggs can also be toxic and unfit for consumption. Leftover hard-boiled eggs can be chopped into salad mixes or sandwich fillings instead of reheating.
6. Mushrooms
Like other leftovers, mushroom dishes should be refrigerated no later than two hours after processing time if they are not used up, and should be eaten the same day without reheating. The protein and nutritional content of mushrooms will break down if heated and can cause various digestive problems. So, it is best if cooked mushrooms are consumed immediately on the same day and try not to heat them.
7. Celery
Because it includes leafy vegetables, just like spinach, the nitrate content in celery will turn into nitrite when heated. If you put it in soup, try to remove the celery in it before the soup is heated. The best way to consume celery is fresh without cooking, such as for juice mixtures or cooking sprinkles. If used for a mixture of dishes, then the menu should be spent in one serving.
8. Red Beets
Although in Indonesia this vegetable is still rarely consumed, but not a few also process it into various types of food. Like spinach, red beets also contain nitrates which are rich in health benefits but can be very dangerous if heated. After being heated, the chemical composition in beets will change and become unfit to eat and harmful to the body. All parts of the beet will turn into nitrite and be toxic. Because red beets are one of the most dangerous vegetables when reheated, it is advisable to consume them fresh – for example in the form of juice. If it's cooked, then finish it immediately.
9. Cooking Oil
Ideally, vegetable oil or other oils (including corn, canola, soybean, and sunflower) used for frying should only be used once. Oils that are used repeatedly until they change color will become saturated fats and contain free radicals. Saturated fat can cause high cholesterol and clog blood vessels which eventually lead to heart disease and stroke. Use a maximum of three times the oil used for frying. Once it has changed color, throw it away.
10. Radish
Usually these vegetables are used as a mixture for soup or stuffing spring rolls and spring rolls. Again, these are vegetables with high nitrate counts. If heated, then the content will change and be harmful to the body. If dishes containing turnips are left at room temperature for more than two hours, then bacteria have started to grow in them. Because radishes contain a lot of nitrates, make sure not to let them cook for too long and don't reheat them. It is highly recommended to eat it fresh and clean.
