thats not the type of aluminum that causes toxicity.
"Aluminum is a growing concern—especially because of its link to Alzheimer’s disease and to other neurological problems which are becoming more and more common. But the difficulty is likely not with aluminum cookware. Many common foods and food additives contain aluminum, including pickling agents (alum), anti-caking agents (aluminum silicates), baking powders (sodium aluminum sulfate), and baking mixes (sodium aluminum phosphate). The average person’s intake from food additives is about 20 milligrams per day. Nondairy creamers, self-rising flour, processed cheeses, and cheese spreads also contain aluminum."
