Who is saying that praying at night is when the food will be taken or made? e.g. Shab-e-raat is tonight and during the day any time you can take food items. Yup - its a tradition and i see no harm in it.
Every one follows religion and knows what holds priority for them, in their own way. The question was only on what should be taken or did you take anything? That does not overlook the importance of the night in any way.
