Refrigerating bananas pretty much stops them ripening, so if you have some fully yellow bananas you can pop then in the fridge and it will stop them from over ripening for a few days. The peel will still go brown but the flesh remains as it was when you put them in. You definitely shouldn't put green bananas in the fridge, but with yellows it buys you some time.

While ideally you'd want a column for serving size, package size, and per 100g, if you're only gonna have one it should definitely be the per 100g since that's the only one that allows you to easily compare between different brands and products.
