why why should we prefer to buy anodized article then and unanodized article of Aluminium ?
Answers
Answer:
Concerns with aluminum cookware come from the fact that measurable amounts of aluminum can migrate from the pot into the food. Several research studies have confirmed migration of aluminum from conventional aluminum cookware at a level of concern for our health. Aluminum is included in the 2007 list of top priority toxins in the United States (a list put out every year by the Agency for Toxic Substances & Disease Registry), and aluminum has been clearly identified as a toxin for the human nervous system (neurotoxicity), immune system (immunotoxicity), and genetic system (genotoxicity).
Anodization is a process in which chemical baths are used to prepare the surface of aluminum to receive an electrical charge that will increase the thickness of the oxide layer and make it harder, more durable, and less likely to corrode. Anodized aluminum is definitely less reactive than non-anodized aluminum and will leach less aluminum as a result, provided that the surface has not been damaged. Although it is more difficult to damage the surface of anodized versus non-anodized aluminum, its surface can still be damaged.
