A study found that there is a significant decline of the nutrient content in 43 different crops between 1950 and 1999

Yeah, higher yield and no change in the nutrient level will mean a decreasing concentration of nutrients.

Here is the problem with crop quality:

1. Most of the purchase decision is what is observable at the store.
   • Does it look good.
   • What is the price.
   • How is the smell, texture, weight…
2. Some happens at home, and you might remember for next time.
   • How does it taste.
   • How long does it last.
   • Does it make you feel satisfied.
3. It is basically impossible to know how good food was for you.
   • You eat a lot of food and the response is delayed.
   • Even if you have a response you probably don’t properly understand your body.
   • In the end most of the “health” of food is just your believes and marketing.

So there is basically no business pressure to have crops be nutritious.
