This worries me a lot. When depressed I would supplement with zinc and magnesium. It helped a bit. Until I learned that one can get it from seafood. It helped a bit. Learning about anti nutrients and how they block the absorption of nutrients was the biggest thing that turned my life around. .. Scientists making flour might just copy from nature but what is it they are making?

food contains many trace elements and things we need that we dont fully understand.

Even slightly changing the natural feed of an animal we eat dramatically changes the quality and nutritional value.

thinking that you can so dramatically change the production (and only produce one part of a food - one of the proteins) all the other elements we need are lost.

It sounds like a recipe for malnutrition.
