"All that glitters is not gold." is an apt expression that comes to my mind when looking for the best cookware! The market is flooded with all kinds of attractive, colorful and shiny cookware mostly made from metals, alloys, and ceramics (a clay-like material). To make the right choice, one must understand the effects of raw material on cooking and food. Let's discuss the effects of different cookware materials on your food's health.

Cast Iron

All metals are reactive, they leach metal ions at the cooking temperature and contaminate food. Iron occurs in its ferric and ferrous form. Our bodies can assimilate (or process) iron from food - plants and meat which is in ferrous form. The ferric form of iron from cast iron cannot be assimilated or digested by our bodies! This ferric iron when combined with the oxygen in the body, can release oxygen-free radicals, which are unstable molecules. And studies now show that the damage caused by free radicals may be the cause for many forms of cancer.

Stainless Steel

Stainless steel is made up of a combination of various metals like iron, nickel, chromium, molybdenum, carbon etc. Even small amounts of these metals in the cellular or organ level can prove extremely toxic. For instance, a very small amount of concentration of nickel can cause kidney dysfunction, low blood pressure, muscle tremors, oral cancer, skin خرید مالتودکسترین خوراکی  etc.

Aluminum

Aluminum is a reactive soft metal that reacts with the different foods and releases its ions into the food. In fact, there is enough evidence today to prove that there is a strong connection between Aluminum and Alzheimer's disease. Chronic aluminum exposure has contributed directly to hepatic failure, renal failure, and dementia.

Effects of These Metals On The Environment

The mining and processing of these metals call for massive deforestation affecting wildlife and they poison the nearby air and water resources. People working in these mines and processing plants suffer irreversible damage to their body due to interaction with toxic gases and chemicals released as by-products of mining, extraction, and processing of these metals.

The people living in nearby areas also face various health problems due to increased pollution levels. They eventually have to relocate to a safer place to save their lives and that of their children.

The Finishing: Enamel, Glazing And Other Chemicals:

Chemical glazes are commonly used these days to make cookware colorful and attractive to the eyes which may enhance their sales numbers but are toxic to the food. These chemicals consist of metal oxides and toxins that also leach into food during cooking. There are three types of coatings commonly used:
