I have developed a theory for the correction of nutritional deficiency diseases and I believe that most diseases are nutritional deficiency diseases. Most diseases like diabetes, hypothyroidism, and hyperthyroidism, don't appear to be deficiency diseases because they involve very complex inter-related nutrient deficiencies. When medical scientists, medical practitioners, or individuals on their own attempt to correct these diseases with a single or limited group of nutrients, they condition invariably fails to respond and often gets worse. I have experienced this, seen it in others, and have a theory of why this happens. Nutritional deficiency diseases which are very resistant to correction involve deficiencies of numerous nutrients.
Some nutrients are very deficient while others are only somewhat deficient.
Some nutrients are key nutrients and when they get deficient this causes other nutrients to be unusable by the body in certain metabolic pathways and therefore they take on toxic-like effects. All nutrients and especially minerals need to be present in the body in the proper balance. When there is a pair of nutrients which work together and one of these nutrients gets deficient, ingestion of the other nutrient causes the less available nutrient to get used up and become even more deficient. For example, copper and iron are key nutrients which are usually deficient in hyperthyroidism. Since copper and iron work together in many functions such as forming hemoglobin, the oxygen-carrying molecule in the red blood cells, a deficiency of copper can cause iron to become toxic to the body.
