It seems like, excepting for artificial foods like twinkies, doritos, coke, etc, there's a trend toward stronger-flavor being more nutritious. I'm thinking of coffee, broccoli, liver, chocolate, red wine, and even produce. Modern-day produce is sold by the pound and bloated with water, unless it's organic. I notice, probably because of this, organic produce has a stronger taste. I remember an NPR program discussing how, per pound, produce is less nutritious now than 50 years ago.
