Chelation. Chelation is a type of bonding of ions and their molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central metal atom. [1][2] These ligands are called chelants, chelators, chelating agents, or sequestering agents.
Many metals, particularly heavy metals are toxic, but some are essential, and some, such as bismuth, have a low toxicity. Metals in an oxidation state abnormal to the body may also become toxic: chromium(III) is an essential trace element, but chromium(VI) is a carcinogen. Only soluble metal-containing compounds are toxic.
Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body. [1] Chelation therapy has a long history of use in clinical toxicology [2] and remains in use for some very specific medical treatments, although it is administered under very careful medical supervision due to various inherent risks, including the mobilization of ...
Researchers analyzed 72 cocoa-based foods — including dark chocolate, often praised as a heart-healthy treat — over eight years. They found that 43% of the products contained an amount of lead ...
Medicinal clay is typically available in health food stores as a dry powder, or in jars in its liquid hydrated state – which is convenient for internal use. For external use, the clay may be added to the bath, or prepared in wet packs or poultices for application to specific parts of the body.
Cinnamon powder sold by Paras contained the highest levels of lead, at 3.52 parts per million, or ppm, according to the report. The next highest level was found in cinnamon powder from EGN (2.91 ...
The metal must dissolve in something the plant roots can absorb. The plant roots must absorb the heavy metal. The plant must chelate the metal to both protect itself and make the metal more mobile (this can also happen before the metal is absorbed). Chelation is a process by which a metal is surrounded and chemically bonded to an organic compound.
Antinutrient. Phytic acid (deprotonated phytate anion in the picture) is an antinutrient that interferes with the absorption of minerals from the diet. Antinutrients are natural or synthetic compounds that interfere with the absorption of nutrients. [1] Nutrition studies focus on antinutrients commonly found in food sources and beverages.
