SOIL FACT#5: We lack Minerals according to USDA, LOW MINErals leads to diseases

According to the US Department of Agriculture (USDA), Americans typically lack a sufficient amount of the minerals calcium, magnesium, potassium and the vitamins A, C, D and E needed to maintain good health. As an example, calcium is essential for the formation of blood clots, the transmission of nerve impulses, as a metabolic cofactor to release energy from macronutrients, for maintaining a rhythmic heart rate and controlling concentrations of substances on differing sides of cell membranes throughout the body. Mild calcium deficiencies can cause heart palpitations, insomnia, irritability, nerve sensitivity, muscle twitching, mental confusion and a feeling of depression. Serious calcium deficiencies can lead to bone loss, a common health problem. Other mineral deficiencies lead to a host of well documented health problems.
