"Overnight food" has nothing to do with "night"

In fact, from a food science standpoint, overnight is not the main issue, the main issue is what happens to vegetables during storage.

Some people worry that nitrates in vegetables will convert to nitrites. The reductase in vegetables can achieve the conversion process, but after the vegetables are cooked, the reductase will lose its activity.

Generally speaking, bacteria are completely eliminated after vegetables are cooked, but they may combine with bacteria in the air during storage or consumption.
