It’s not just our produce. My grandmother who grew up on her farm constantly complains about milk being bland and flavorless these days. She said most milk cows are Holsteins and they give awful milk, but produce a much larger quantity. I’d live to taste milk from other cows to see for myself. I also hear that pigs today are bred for gaining weight as fast as possible and not for taste. I read an article about heirloom pork farmers and not only were the pigs treated much more humanely, they also tasted much better as well.
It’s not just the breeds either. Factory farm eggs are flavorless compared to true free range chicken eggs. In the factories, the chickens only eat their feed. When they roam outside, they get to eat all kinds of different seeds, bugs, and worms. It makes their yolks a darker color and the flavor is amazing.
