I can't say if the examples you have noted are culture related or not.

I loved living in Japan and being immersed in Japanese culture, but that doesn't mean I didn't eat cheeseburgers and fries when I could. I would travel into Osaka on Sundays just to buy bagels.

I know Japanese people in America who have lived here for many years, but still don't feel they have had a complete meal unless they have steamed rice.
