Is food in your country/area that expensive? I live in an expensive city in the middle of Europe and get most of those things for half the price in a normal supermarket. If I optimize for sales and seasons, I even get cheaper prices, while still have a divers healthy diet. Even more so if I buy in bulk and prepare in advance. But to be fair, it would demand more time and knowledge, which is not for everyone.
