2 clean oatss ranked by lowest ppb

Plain and flavored oats sit at the heart of the glyphosate contamination problem. Pre-harvest spraying deposits residue directly on the grain, which survives milling and processing. EWG found that even "simply made" oatmeal brands contain significant residue. Organic and glyphosate-free certified oats are available and deliver clean nutrition without the exposure. The picks below are the cleanest oats we found, ranked by glyphosate level (lowest first). Each has been lab-tested by an independent third party.
