You probably don't even know what real vegetables taste like. As a Canadian born and raised who moved to Ukraine a few years ago, one of the most surprising things I encountered was how tasty a simple salad can be. Then I found out that mineral levels in vegetables in North America are estimated to have dropped 90% since 1914 [1]. Ukrainians who migrate to other countries are often heard to complain about a loss in food taste - and I know exactly what they're talking about because I'm a foreigner who noticed the difference in food taste right away.
