Many people pay attention to nitrite because they are worried about overnight dishes. Vegetables will produce nitrite overnight. Although nitrite is not a carcinogen, it will be converted into nitrosamines under certain conditions. Nitrosamines are carcinogens. Eating overnight dishes can cause cancer?
The answer is no, although overnight vegetables will produce nitrite, but the quantity is limited. If you want to cause cancer, you need enough carcinogens. The nitrite content in overnight dishes is not high. Unless you eat overnight dishes every day and eat them for decades, you may cause cancer because of eating overnight dishes.
Since the nitrite contained in overnight dishes will not cause cancer, can overnight dishes be safely eaten? Here again, it is not recommended that you eat overnight dishes. The reason is not nitrite in overnight dishes.
Leave the food overnight and you may find the problem. These dishes are more salty than when they were first cooked. The reason is that after soaking in vegetable soup all night, the salt in vegetables is higher than before. This leads to a high intake of salt. Eating too much salt will increase the risk of gastritis, hypertension and osteoporosis.
When eating, many families have no habit of sharing meals. This practice of many people eating one dish has caused cross-infection of bacteria, and the remaining dishes are actually not fresh, and more bacteria are bred. Although leftovers can be stored in the refrigerator, bacteria still exist. The next day, even if heated, the temperature will not be too high. Therefore, these bacteria can cause diarrhea and other food problems into the human body.
The edible significance of overnight dishes is actually not great, and the nutrients contained in them have already been greatly reduced. However, some people choose to continue to eat overnight dishes because of economic conditions. What should they do at this time?
Cold salad is not cooked at high temperature, so even if it is left, it has no value to continue eating. As for meat dishes, they can only be eaten after high temperature and heat penetration. If you cook a lot at night, you can put the possible leftovers on a separate plate in advance and store them in the refrigerator while they are hot.
The main purpose of putting vegetables in the refrigerator while they are hot is to reduce the growth of bacteria. The reason lies in the temperature at which bacteria multiply in dishes. The reproduction of bacteria needs a certain temperature and humidity. Too high or too low temperature is not conducive to the reproduction and proliferation of bacteria. If you cool the food at room temperature and put it in the refrigerator, it is equivalent to putting the bacteria and vegetables in the refrigerator together.
Overnight dishes can be reheated and eaten. But relatively speaking, the value of eating is not great, and it is better to choose fresh food. Fresh-fried dishes are also more nutritious.
