The iron found in your blood and interstitial fluids (like your tears) are in the ionic form. The same is true of sea water otherwise the minerals in the oceans would render the water opaque. As soon as an ion of iron or any other mineral assembles into structures such as crystals, it can no longer participate in cellular homeostasis and is now categorized as a heavy metal. The "environment vitale", is the ancient ocean that bathes each cell with the essential nutrients for good health. When recognized by the immune system these Heavy metals are sequestered by wrapping these toxins in scar tissue and locking them away in our adipose tissue . There, in our fat, they vibrationally irritate adjacent tissue. Over time the cell's nerve connections go dormant so that the immune system is no longer alerted to parasitic infestation. In this way, heavy metals lead to further toxifying your body's saline. All processed food implies these dangers. Eat from trees, not factories
