The site states that toddlers age 9 months and older are typically ready for Cheerios, and even touts "the fact that 4 of 5 pediatricians recommend Cheerios as a finger food." You may further believe Cheerios to be a good choice because they don't contain genetically engineered (GE) ingredients.

Oats are the primary ingredient (there are no GE oats), and the corn starch and sugar they contain come from non-GMO corn and non-GMO cane sugar. So why the warning against this family favorite?

Despite their GMO-free status, testing completed at Anresco, a laboratory registered with the U.S. Food and Drug Administration (FDA), found glyphosate residues in Cheerios as well as other popular foods.

Glyphosate, the active ingredient in Monsanto's Roundup herbicide, has made headlines recently because it's the most used agricultural chemical in history and also because the International Agency for Research on Cancer (IARC) determined it is a probable carcinogen.
