Is eating leftovers harmful to your health for a long time?

Eating leftovers for a long time is harmful to nutritional balance and digestive system function. The nutritional content of leftovers will be greatly reduced, so eating these things can't be compared with eating fresh ones. In addition, leftovers are also easy to breed bacteria and carcinogens. The nitrite content in these foods is significantly higher than that in fresh foods, and long-term consumption will increase the risk of cancer. This bacterium can easily lead to gastroenteritis and intestinal flora imbalance, induce Helicobacter pylori infection, and then trigger a series of digestive system diseases. In order to prevent waste, many people often put this meal into the next meal and then eat it in the microwave oven or in the refrigerator. It is not right to eat the next meal after it is hot, because eating leftovers for a long time is very harmful to the body, such as the symptoms of acute gastroenteritis, because long-term food is easy to deteriorate and breed bacteria, and after eating it, there will be nausea, vomiting, diarrhea and other symptoms. Eating leftovers for a long time will lead to the increase of nitrite content in the body, which will lead to the risk of cancer, so it is recommended not to eat leftovers for a long time, which is of great help to the human body.
