Salad veg such as tomatoes, cucumbers and peppers are better stored at room temperature.
Nuts, apples and flour should all be kept in the fridge.
Dietician Dr Duane Mellor says cold storage prevents the oils in nuts from going rancid and helps kill weevil eggs laid by bugs in flour.
The Daily Mail also reports salad veg such as tomatoes, cucumbers and peppers are better stored at room temperature, similar to when you buy them in a supermarket.
