Some foods and ingredients are capable of being left unphased by being stored out in the open. Most notably, fruit is perfectly fine to be left out in the open. It will still eventually go off but that is not due to being stored incorrectly. Fresh food such as pasta, baked goods, and chips are just some of the foods that you should take good care of when storing. The incorrect storage of these snacks or ingredients will eventually lead to a lower quality food or experience which is not something you want while trying to eat. Bread and chips especially will be a lot worse if you leave them out in the open as the bread will go stale and hard, while the chips will go soft. This is not what you want when it comes to eating them. Meat is also in need of being stored properly or it will be a growing house for bacteria.
