While the pots and pans that are manufactured today are done so under great scrutiny and care, many avid collectors (and users) of vintage cookware have question about the safe use of favorites such as Guardian Service and VISIONS. Since there are two sides to every story, we decided to check the research for answers.
Beginning in the 1970's, concerns were voiced about possible harm from aluminum leaching from pots and pans after autopsy results showed trace aluminum in the brains of people with Alzheimers Disease. Subsequent to the outpouring of concern, much research has been done to either support or disclaim the statement. National Institute of Health (NIH) studies have found that there is no conclusive evidence linking aluminum with Alzheimer's Disease, and reports that cookware releases very little aluminum into foods (Neville, 2005). Of note, other sources of aluminum, such as foods, food additives, drinking water, and medications (especially antacids) contribute the most aluminum (Neville, 2005).
Verdict: Safe to use, but replace when you see signs of "pitting"(tiny holes)(Neville, 2005).
Of all cooking material, Teflon has recieved the most scrutiny. Those that collect, use, or sell the Silverstone coated Corning Ware VISIONS are well aware of these concerns. Whats the scoop? The latest controversy of the use of perfluorooctanoic acid (PFOA), also known as C-8, occured when the Environmental Protection Agency upgraded PFOA to a "likely" carcinogen (Neville, 2005). The good news is that PFOA is not found in the finished product of Teflon, the bad news is that production of teflon does cause a safety issue for workers in those plants.
The verdict: If you don't cook over high heat and you replace it when chipped it is safe to use (Neville, 2005). Cooking over high heat means 500 degrees sustained for 8 minutes per the article. This will cause a "fume" which is known to be harmful to pet birds (you should not keep pet birds in your kitchen because of potentials such as this (Neville, 2005)).
THE BOTTOM LINE
Of course the bottom line is that individual's must do what they feel is right for them and the ones they love. Will you use aluminum and teflon-coated cookware? Research supports the safe use of aluminum and teflon in cooking. The caution is similar to most things we humans use: be informed and use common sense.
Do you have recent findings? If so, stop by and keep us up-to-date.
