The higher the exchange rate the more purchasing power for food because food is not imported assuming it is not. But in capitalist countries like Philippines where compost is available, where we have indiginous materials to use for animal feeds and we do not need to import fertilizers, food is cheaper. I just don't know about socialist Belorussia. Everywhere you go you see either market or food vendors. Even in sidewalks and busy streets. The more competition the more stable the prices are because nobody can dictate the prices. Again, I do not know how Belorussian law works on street and market vendors. Do they allow market vendors on the streets and provincial market?
