From Martha Stewart Living:

The facts about pots and pans, however, tell a different story. Current studies have all but exonerated aluminum cookware from any connection to Alzheimer's. Most have an anodized surface that reduces the amount of metal seeping into food.

Don't grind the pans. You'll introduce rough surfaces to more staining, introduce metal particles into your air, and remove the anodized surface the quote speaks of.

Healthy Cookware. This article rates types of pots and pans. Do yourself a favor and save the energy--buy a good, new, healthy set of pans.
