My sister and her boyfriend are vegans and a few of my friends are vegetarians(of the fish isn't meat kind), so far from it. :P
In general, last 15 years(and last decade especially) there is some push toward staying fit in Poland, resulting in constantly rising popularity of "bary mleczne", reduction of red meat consumption and avoidance of traditional polish cuisine at least by younger population.
Actual data shows that there is lower consumption of meat in Poland than in Germany(78.1 vs. 82.1 kg/per capita, respectively).
Oh wow, I had no idea! The Polish-Americans I know and hang out with tend to eat more of the traditional stuff, and my Grandma would always make half-jokes like "I'm so glad none of us are vegetarians, just look at this ham". :) Similar to how Norwegians in the USA eat three times as much Lutefisk as Norwegians in Norway!
