It is hard to eat a healthy diet when you eat at fast-food restaurants often, the site goes on to say. Many foods are cooked with a lot of fat, even if they are not trans fats. Many fast-food restaurants do not offer any lower-fat foods.
Lithuanians will speak Russian automatically, Polish is a different language but they will have learnt Russian in school in the same way that English children learn French, that is - because they're the immediate neighbours. In the Old DDR, they taught Russian as the second language automatically. Some schools there still do.
To provide you a little more information what languages they speak I should say that it's quite popular to speak more than one language in Baltic countries. Therefore there are a lot of Latvians, Lithuanians and Estonians who would be able to speak one or two languages in addition to their native language.
