Actually you should not be cooking in aluminum at all.The stuff leaches out of the cooking pans and foil and winds up in the food. If you can taste it, you are certainly getting it.The aluminum industry certainly WILL NOT discourage use of its products. Teflon over aluminum cookware is doubly poisonous. Soda (an acid) stored in aluminum cans is certainly a culprit. Aluminum is also featured along with mercury in many vaccines, and is considered a leading cause of autism in children - vaccine damage.Dr. Hulda Clark in her many research books, such as "The Cure for All Dis-Eases", points to combinations of toxic metals lodged in body tissues along with parasites as the causes for most diseases, including cancers, infertility, allergies, and things like fibromyalgia.In other words, switch to Pyrex or Corning ware, or use only stainless steel cookware.
