Soy-based infant formulas found to contain exceptionally high amounts of aluminum
As previously mentioned, aluminum is everywhere these days. Some municipal water supplies add it in the form of aluminum sulphate to make drinking water appear clearer, and thus cleaner. Processed cookies and cakes often contain it as a raising agent as well.
Everything from food coloring, tea, cocoa, wine and sparkling beverages to toothpastes, sunscreens and various other cosmetics contain aluminum. Even popular pharmaceuticals like aspirin and antacids contain it as an additive, as do many childhood vaccines, typically in the form of thimerosal, which is roughly 50 percent ethylmercury by weight.
A lesser-known, but much more concerning, source of aluminum is soy-based infant formulas. According to the United Soybean Board, which advocates in favor of soy as a food additive, soy-based infant formulas contain high levels of aluminum because soybeans accumulate it from the soils in which they are grown.
"The [aluminum] content of a range of well known brands of infant formulas remains high and particularly so for a product designed for preterm infants," explains a 2010 study published in the journal BMC Pediatrics
