I heard there are possible reactions with some foods. Is there some websites explaining this ? thks Wed Nov 17 15:39:37 -0800 2004 0 Han Lukito 1 1656931 If it is plain aluminum and not anodized you should not cook acidic foods in it. The acid can pit the aluminum. So no tomatoes, apples etc. Wed Nov 17 16:04:40 -0800 2004 1656928 0 Candy 1 1656945 There were also those rumors a while back about aluminum cookware contributing to the development of alzheimer's later in life. Please, someone, tell me that theory has been discredited. Wed Nov 17 17:38:05 -0800 2004 1656928 0 GGG 2 1656947 See #5 below.

It was found that there is an abundance of aluminum in the brains of Alzheimer's patients but it was proven not to have been directly linked to cookware, the study I believe showed that the aluminum was an effect not a cause. Aluminum is abundant in many things that we eat as well as drink and use, like antiperspirants. You cannot get enough aluminum from cookware to cause Alzheimers. It is time for that myth to go away.
