True that we haven’t been purposefully breeding the nutrition out of our food, I should rephrase that to ‘we’ve been untintentionally breeding the nutrition out’ by focusing on things like yield, shelf life, transportability, which all negatively correlate to nutrient density. Like we did by selecting and propogating super sweet mutations like the Golden Delicious. I suspect we’ve been ‘drifting towards sweetness’ for as long as humans have been domesticating crops, the process has just sped up after the advent of things like mutagenesis using gamma radiation in the 70’s. I think a conversation needs to be had, if ‘food as medicine’ is an actual goal of some people, that we need to spend more time studying the genetics of nutrient density.
