Nutrient Decline and Deficiency
Updated December 2, 2021
Food & Supplements Program
Nutrient levels have been declining in the soils for almost 100 years. There is similar declining nutrient levels in our crops, in part due to the soils, but also to the selection of high-yield crops and climate changes. Even organic foods, while having better nutrient levels and lower pesticide/toxic levels, are not the crops of 100 years ago. How much iodine, manganese, molybdenum, strontium, cobalt and other nutients required for soil fertilizers, even organic, is not precisely known. Measuring mineral and other nutrient levels in soils, as well as the human body, is subject to many assumptions and potential errors.
