Studies have shown that the nutrient content of our soil has been depleting over the years due to modern agricultural practices like over-farming, use of synthetic fertilizers, and lack of crop rotation, which lead to soil erosion and loss of important minerals. A landmark study by Donald Davis and his team from the University of Texas (UT) at Austin’s Department of Chemistry and Biochemistry published in 2004 found substantial decreases in the amounts of protein, calcium, phosphorus, iron, riboflavin and vitamin C in vegetables and fruits over the past half century. #minerals #thyroidproblems #supplements #fyp @Optimize Minerals
