An internal analysis of high fructose corn syrup by an investigator at the Food and Drug Administration is trickling out, four years after the samples were taken.
And, that study, printed in the journal Environmental Health this week found mercury in some samples of corn syrup, a primary ingredient in most common processed food products from Pop Tarts to barbeque sauce.
A second study found low levels of mercury in many products, taken off the shelves at grocery stores.
The Corn Refiners Association disputes the claims in both studies.
So little is known about how mercury is metabolized in our bodies. Some believe low levels of mercury pass in and out of our bodies all the time and that nutrients in our diet helps process the metal. For those who are concerned about mercury in processed foods, eat more foods with zinc and selenium in them.
