Vegetable Oil

This happens because reheating polyunsaturated oils that contain linoleic acid (sunflower oil, canola, and corn oil) releases 4-hydroxy-trans-2-nonenal (HNE), a toxin derived from fatty acids. This toxin can only do harm to your body, and it is contacted to the Alzheimer’s and several types of cancer. So be careful and don’t reheat vegetable oil.


The Food Standard Agency claims that uncooked rice has spores of harmful bacteria that can even survive the cooking process. So, if you store your rice at room temperature, these spores can multiply and make numerous digestive problems. They can also survive reheating, so scientists say we should eat all the rice we cooked at once, and if we have any leftovers, we should freeze them or keep them in a fridge for one day.

Leftover vegetables should be stored at -4 C, according to the Center for Food Safety, and if you want to store them for a longer period of time, you should freeze them. All of this doesn’t apply to all veggies, just for some of them. Beets, lettuce, celery and spinach have high levels of nitrates that can cause trouble when exposed to room temperature. They can cause methemoglobinemia in children, a rare blood disorder which causes symptoms such as fatigue, shortness of breath and seizures.

This fact is important when you use the microwave because it doesn’t reheat meals evenly. Also, keep in mind that you can eat this kind of meat up to 2 days, not a day longer.
