That's not what led to lack of taste and nutrition. It was consumer preference combined with food supply chain logistics. People wanted redder apples, and stores wanted apples that stored well, shipped well, and were cheap. So they grew, shipped and sold Red Delicious. It's not tasteless because of farming, it's just a shitty apple. The marketplace gave the consumer (and seller) what they asked for. Other produce does now has less nutrition (due to the farming methods you mention), and they could improve the produce if that was their goal. But it's not, because people aren't demanding improved produce. They demand "Organic", because they fear unorganic, because they fear it's going to make them sick. They don't fear a lack of nutrition (or taste), so they aren't concerned with it, so they don't demand more nutritious or delicious food, so it isn't made that way. Americans have been programmed since the 1950s to prefer convenience, salt, sugar, and fat, over quality. Go to France, see how they eat, what produce they have. It's not because their farms are different. Their consumers just want good quality, local, seasonal food. So they get it.
