Sad that people have misconceptions of Polish food. When I stay with my family, we eat very healthy, mostly fresh vegetables and they never use lard, cream very sparingly once in awhile, barely ever. I know in Krakow now there are a lot of healthy choices and vegetarian restaurants as well.
Maybel Polish people don't have low fat, no salt & low sugar cook book yet. Most of receipes may not taste good.
I wouldnt be so sure of that, I bought some great vegetarian cookbooks on my last visit to Poland (po polsku, of course)
