The Glyphosate Food List

This shocking glyphosate food list was compiled from three different studies conducted since 2016 that measured the levels of this toxic chemical in grains, cereal, breakfast bars and snacks.

This shocking glyphosate food list was compiled from three different studies conducted since 2016 by the Environmental Working Group, Food Democracy Now and the Center For Environmental Health. These studies measured the levels of this toxic chemical in grains, cereal, breakfast bars and snacks.

Glyphosate is the active ingredient in weed killers like Round up. More than 250 million pounds of this toxic chemical are sprayed on American crops every year, especially on “Roundup-ready” corn and soybeans. These crops are genetically engineered to withstand the herbicide.

And even if you don’t use Round up as a weed killer in your yard, there’s a great chance your town’s parks and rec department, golf course and probably your neighbors all do. That’s because it’s the most widely used herbicide on the market.

Health Effects Of Exposure

Thanks to lots of misinformation and big bucks spent by Monsanto, the makers of Roundup, glyphosate-based herbicides have a bogus reputation for being safe. Because in reality, animal and human studies of exposure have found that glyphosate can affect your health in a bunch of different ways.

Exposure can:

If that list isn’t scary enough, glyphosate also messes with your body’s ability to breakdown other toxins you are exposed to everyday.

Plus, credible independent, peer-reviewed scientific evidence also now shows that the level of exposure that could harm your health begins at the ultra-low levels of 0.1 parts per billion (ppb). Unfortunately. a UCSF study found that 93% of us have an average level of 3.096 parts per billion (PPB) in our bodies.

And despite claims by Monsanto that glyphosate is quickly broken down in your body and excreted, there’s also growing scientific evidence that it builds up in your body. And not just in body fat. It can actually build up in organs and bones. It builds up in bones due to its strong ability to bind with calcium.

Why The Levels Are So High

When you look at the levels in the list below you might wonder why they're so high in oats and other grains. There are a couple of reasons.

First, as I already mentioned, glyphosate is the most used herbicide in farming. GMO crops are genetically designed to survive this herbicide. So they can be heavily sprayed.

Because glyphosate is absorbed into the plant’s cellular structure in order to kill weeds, the chemical can’t be removed from GMO crops and other plants by washing, peeling, baking or brewing grains.


Another more recent reason for the high levels found on food is that farmers spray glyphosate on crops like oats, wheat, barley and edible dry beans as a pre-harvest drying agent. In other words, this process kills the crops and dries them out faster. This means the crops can be harvested sooner. 

While this pre-harvest use of glyphosate may account for a small amount of overall use of the herbicide, it accounts for well over 50 percent of your dietary exposure.

The top 10 highest levels found in the foods tested are listed below. You can download a complete glyphosate food list of the levels found in all the items tested in the 3 studies here.

What You can do 

The best thing you can do is to switch to non-GMO and organic grains. Glyphosate can't be sprayed on crops that aren't "Round-up Ready", meaning genetically modified so they won't die when sprayed.

But it can be sprayed on non-GMO crops as a pre-drying agent. Unless the crops are grown organically.

You’ll see from the complete glyphosate food list that the lowest levels -with one exception - of glyphosate were found in organic foods. The low levels found in organic foods come from glyphosate drifting from nearby fields of conventionally grown crops, or by cross-contamination during processing at a facility that also handles non-organic crops

Also, 2014 study reported that people who ate conventional diets had much higher glyphosate residues in their bodies than those who ate organic food. For more reasons to go organic check out Pesticides In Fruits and Vegetables.
