In fact, if it is a canned vegetable, don't say 'overnight'. There are not many changes in the 'every month' or 'every month' period. There are many literatures on how the storage time and storage conditions of vegetables affect the nitrite content. The conclusion is that refrigeration can greatly reduce the production of nitrite.
From this point of view, 'overnight' is not the key to the production of nitrite, heating will not increase the content of carcinogens. 'Evening food' can not eat in the end, we can not generalize.
