A few remarks...

* The general population does have a bunch of nutrient deficiencies in their diet - https://www.healthline.com/nutrition/7-common-nutrient-defic... as an introduction to the problem

* The article is making claims about a 100 year timespan and I doubt we have comparable data on nutrient deficiencies which is that old

* Daily calorie intake has probably doubled in that time period, so in theory you'd hope daily intake of all essential nutrients would double as well, but here we are with almost half of women and children having iron deficiency, with widespread deficiency in vitamins D and B12, half of the population not getting the recommended calcium intake etc.

So I think as an example to start throwing some numbers out there. About 40% of Americans don't get the recommended amount of calcium. First chart in the article shows calcium in vegetables at retail declining by 90% in the last century.

I think we have evidence establishing that nutrient deficiency leads to cravings - maybe declining nutrient density is a factor encouraging overeating and obesity?

Pretty interesting topic
