Some foods can become toxic overnight, so be careful not to eat them indiscriminately.
One, Soup The best way to store soup is not to add seasonings like salt to the base. After cooking, ladle out the portion you plan to drink that day with a clean spoon. For the leftover soup, it's best to store it in a clay pot in the refrigerator. Leaving leftover soup in aluminum or stainless steel pots for a long time can easily lead to chemical reactions; it should be stored in glass or ceramic containers.
Two, Fish and Seafood Fish and seafood can easily produce protein degradation products overnight, which can damage liver and kidney function.
Three, Bulk Braised Foods Bulk braised foods should be finished on the day they are made and not kept overnight. From a food safety perspective, this is unhygienic. If possible, it's best not to eat leftover braised foods. Food experts remind us that even food stored in the refrigerator is not absolutely "safe." The refrigerator is a place where molds and psychrophilic bacteria can easily grow.
Four, Tea In overnight tea, most vitamins have been lost due to the long time, and the proteins and sugars in the tea infusion become nutrients for the growth of bacteria and molds.
Five, Leafy Green Vegetables Some leafy green vegetables contain high levels of nitrates. If cooked and left for too long, bacteria will break them down, reducing the nitrates into nitrites, which are carcinogenic and cannot be removed by reheating.
Six, Tremella (Wood Ear Mushroom) Whether cultivated indoors or on hardwood logs outdoors, tremella contains a high level of nitrates. If cooked and stored for a long time, bacteria will break it down, reducing the nitrates into nitrites.
Seven, Eggs If an egg is not fully cooked, consuming the uncooked yolk overnight, especially if stored improperly, can easily lead to bacterial growth, causing issues like gastrointestinal discomfort and bloating. However, if the egg is fully cooked and properly sealed and stored at a low temperature, it is generally safe to eat.
