Bad news for anyone who likes to eat cereal, or granola bars, or anything that contains oats at all: a recent study by the Environmental Working Group (EWG) tested 45 conventional oat products for the presence of glyphosate, and researchers found it in 43 of them. And, of these 43 oat products, 31 had amounts of glyphosate that were far above the EWG’s Health Benchmark of safe ingestion amounts.
