Should I separate multiple “ands” in a series with commas?

I enjoy eating apples and cherries and pears and bananas.

OR

I enjoy eating apples, and cherries, and pears, and bananas.

I apologize if this question was listed somewhere else, but I can't find a single article discussing it anywhere on the internet. I'm a transcriber. I'm not at liberty to change what a person says, but I need to type it up on paper with best possible grammar. My company prefers the Oxford comma, so the last comma in a series is preferable.

Best Answer

There is no grammatical need for those commas; the conjunctions are perfectly adequate by themselves to connect the listed items. (This is an example of polysyndeton.)

The Oxford comma is normally used in a series only when commas are used for the series connectors. Therefore, in the absence of any other information, I'd recommend the first sentence that you suggested:

I enjoy eating apples and cherries and pears and bananas.
