The sick brain cells of people with Alzheimer's disease have been found to contain high amounts of aluminum. This prompted people to point a guilty finger at aluminum pots and pans as a source of this element that they believe damage brain cells, resulting in senility. Countless people tossed out all their aluminum cookware, replacing it with stainless steel and enameled cast iron. But what those who panicked failed to realize is that sick cells tend to accumulate toxic metals because they are unable to eliminate them. Despite numerous investigations, there is no scientifically reliable evidence that aluminum is the cause, rather than the result, of a diseased brain.
Antiperspirants cause breast cancer.
A persistent Internet myth is that since antiperspirants block sweat glands, those in the underarm are unable to eliminate toxic substances, sending them instead into nearby lymph nodes, where they cause genetic mutations that result in cancer. First, sweat glands do not eliminate toxins and are not connected to the lymph system. Rather, toxins are processed through the liver and kidneys. Second, breast cancer does not arise in lymph nodes. It may spread to underarm nodes, but it starts within the breast tissue, usually in milk ducts.
