I used to believe that we should be able to get all of our body’s nutrients from a well balanced and varied diet. Well, I got schooled on that cute sentiment while learning about nutrition.
I wish we could get all our necessary vitamins and minerals from the food we eat, but that ship sailed along time ago.
We lose 1% of our top and its nutrients annually.
This is a resource that is not renewable, once it’s gone its gone. Soil erosion is just one factor in the depletion of nutrients in our food and we can thank monoculture, pesticide/fungicide and pollution for that.
Unfortunately, our food today is significantly less nutritious.
