Food / A report on certain Polish eating habits [15]

I actually just have a few questions that I am hoping someone (or a few people) would be able to answer. My girlfriend has to do a report on certain Polish eating habits and as of now has been unable to loacate the information she needs. If someone could answer these questions, it would be much appreciated!

What meals are typically eaten throughout the day (breakfast, brunch, lunch, dinner, supper etc.)?

Who generally makes the meals? Just one individual? Are the duties shared (Husband cooks dinner and wife cooks supper)?

Approximately what time of the day is each meal made (Breakfast at 7AM, Dinner at 7PM etc.)?

What type of food items are typical for each meal?

As I am not 100% sure on all of the information she needs, any other information that is related or you feel may be helpful, feel free to add it in. I greatly appreciate any help that you may give, Thank You!
