The primary location for zinc absorption is the small bowel. Zinc absorption is known to be affected by dietary factors. A deficiency of zinc plays havoc in the body's ability to process other minerals. The chain makes sense. If HFCS hinders zinc absorption, a lot of things could be affected including DNA synthesis, neural function in specific regions of the brain (speech and taste), and a whole host of other issues. The buildup of the unprocessed minerals (mercury et al) could be directly related to zinc levels. Interesting............
Another social pattern that affects zinc absorption - human milk increases absorption. What correlation could be drawn between the shrinking number of nursing mothers and the rise in autism? Could be interesting.
Many years ago a study at the University of Florida found that autisitc children had an elevated amount of milk protein in their blood.
