The study revealed that baby rodents weaned on a iron-fortified formula equivalent to that consumed by infants developed increasing amounts of Parkinson's-associated brain degeneration as they aged.
"Since this is a mouse and not a human study, it awaits epidemiological verification in human populations," cautioned study co-author Julie K. Andersen, a faculty member with the Buck Institute for Age Research in Novato, Calif.
"However," she added, "our data would suggest that this should be looked at to see if there is any correlation between infants receiving iron-fortified formula and later susceptibility for Parkinson's disease."
