A good sign of weak digestion is low blood mineral levels. A sufficient supply of minerals is necessary for an efficient and capable immune system. For example, critical minerals such as magnesium, chromium, and selenium may be low due to inadequate hydrochloric acid in the stomach, thus hampering efficient digestion.
One study reported that a vast majority of Americans are deficient in the mineral magnesium, an element critical for optimal organ function. Few of us are aware that magnesium is a part of a powerful nutritional strategy in the prevention and treatment of medical conditions such as constipation, headaches, diabetes, anxiety, kidney stones and depression. Below normal levels of magnesium is a contributing cause of cholesterol forming plaques.
