Snacking is not a modern concept. As humans, we have been snacking for our whole existence.The Stone Age hunter will have eaten berries while waiting for his next rabbit, Native Americans used to throw their ears of corn on a fire to produce early popcorn, and the first pretzels are said to have been made by a 6th century Italian monk.
However, along with this snacking behaviour, we also started to eat larger, regular meals a few thousand years ago once we started breeding livestock.
