According to a study published in Environmental Research, switching to an organic diet can reduce levels of the herbicide glyphosate in the body by an average of 70% in just six days. This startling fact highlights the pervasive nature of this weed-killer in our food system and the significant impact dietary choices have on exposure to it. Learning what food does not contain glyphosate is crucial for anyone seeking to minimize their intake of this potentially harmful chemical.

Quick Summary

The herbicide glyphosate is found in many conventional foods, but a diet focused on certified organic, Glyphosate Residue Free-labeled, and certain naturally low-residue foods can significantly reduce exposure. Key strategies include prioritizing whole foods, supporting regenerative and local farming, choosing grass-fed meats, and filtering your drinking water.

Key Points

Prioritize Organic: Choosing certified organic products is the most effective way to minimize your exposure to glyphosate, as its use is prohibited in organic farming.
Look for Certifications: For processed foods and grains, seek out the 'Glyphosate Residue Free' label from third-party testers like The Detox Project for added assurance.
Eat 'Clean 15' Produce: Focus on fruits and vegetables from the Environmental Working Group's 'Clean 15' list, which are less likely to carry pesticide residues.
Choose Clean Proteins: Opt for grass-fed, pasture-raised organic meats and wild-caught fish to avoid glyphosate contamination from animal feed.
Be Mindful of Grains and Legumes: Conventional oats, wheat, and chickpeas are high-risk due to pre-harvest desiccation. Always choose certified versions of these items.
Filter Your Water: Use a high-quality water filtration system to remove trace amounts of glyphosate that can enter the water supply through agricultural runoff.
Limit Processed Foods: Minimizing consumption of processed cereals, snacks, and packaged foods made with conventional grains can help reduce overall exposure.

The Ubiquity of Glyphosate in the Food Supply

Glyphosate is the active ingredient in many herbicides, most notably Roundup. Its widespread use in conventional agriculture has led to its presence in numerous food products. Farmers use it in several ways that lead to food contamination:

During Cultivation: It is sprayed on fields to kill weeds and is tolerated by genetically modified (GMO) crops engineered to be resistant to it, such as corn and soy.
As a Desiccant: In a process known as pre-harvest desiccation, glyphosate is sprayed on certain non-GMO crops, like oats and wheat, just before harvest to dry them out. This practice accelerates the harvesting process but results in higher residue levels in the final product.
Environmental Drift: Glyphosate can spread to neighboring organic farms through wind and water runoff, leading to accidental contamination of otherwise clean crops.
Animal Feed: Conventional livestock is often fed crops treated with glyphosate, which can transfer the chemical into animal products.

Given these pathways, actively seeking out foods with no detectable glyphosate is a vital part of a clean eating plan. The following sections provide a comprehensive guide on how to build a diet with minimal or no glyphosate content.

The Power of Organic and Certified Labels

One of the most effective ways to avoid glyphosate is to choose products with specific certifications. While no food can be guaranteed 100% free of all contaminants due to environmental factors, these certifications provide the highest level of assurance.

Certified Organic

Certified organic farming standards strictly prohibit the use of synthetic herbicides like glyphosate. By choosing USDA Certified Organic products, you can significantly reduce your exposure, as multiple studies have shown. However, it's important to remember that trace amounts of glyphosate can still be found in some organic products due to environmental drift from nearby conventional farms. Despite this risk, organic remains the best default choice for minimizing intake.

The Detox Project's Glyphosate Residue Free Certification

For an even higher level of assurance, look for the 'Glyphosate Residue Free' label from third-party certifiers like The Detox Project. This certification means the final product has been tested by an accredited lab and contains no detectable glyphosate residue. This is particularly useful for processed foods and products where cross-contamination is a concern.

Low-Residue Produce: The 'Clean 15'

Every year, the Environmental Working Group (EWG) releases lists highlighting produce with the lowest and highest pesticide levels. The 'Clean 15' list features fruits and vegetables that tend to have the lowest pesticide residues, including glyphosate. Incorporating these items into your diet can reduce your overall exposure even when buying conventional produce.

EWG Clean 15 examples: avocados, sweet corn, pineapple, onions, papaya, sweet peas (frozen), asparagus, honeydew melon, kiwi, cabbage, mushrooms, cantaloupe, mangoes, watermelon, and sweet potatoes.

High-Risk Food Categories to Approach with Caution

Certain food groups are more likely to contain high levels of glyphosate residues, especially when conventionally grown. These include:

Grains and Legumes: Crops like oats, wheat, barley, chickpeas, and lentils are frequently sprayed with glyphosate as a desiccant, leading to higher residue levels.
Processed Foods: Many snacks, cereals, and baked goods use conventional oats, wheat, and corn. These processed products have repeatedly tested positive for significant amounts of glyphosate.
GMO-Heavy Crops: Corn, soy, canola, and sugar beets are often genetically modified to resist glyphosate, allowing for heavy application throughout the growing season.

What Food Does Not Contain Glyphosate?

Building a clean, nourishing diet means choosing whole foods that are naturally free from or have minimal risk of glyphosate contamination. Here is a list of excellent choices to build your meals around:

Organic Fruits and Vegetables: Prioritize fruits and vegetables labeled 'certified organic'. For produce, consider the Clean 15 as your conventional fallback option.
Certified Glyphosate-Free Grains: Opt for grains like certified organic or Glyphosate Residue Free oats, quinoa, millet, and buckwheat. Some brands are specifically tested and certified.
Grass-Fed and Pasture-Raised Animal Products: For meats, poultry, and dairy, choose products from animals raised on organic, glyphosate-free feed. This ensures the chemical doesn't enter the food chain through contaminated animal feed.
Wild-Caught Fish: Fish that are wild-caught are not exposed to glyphosate through agricultural feed, making them a safe protein choice.
Filtered Water: Since glyphosate can contaminate water sources through runoff, filtering your drinking water can further reduce your overall exposure.
Fermented Foods: Probiotic-rich foods like sauerkraut, kimchi, kefir, and kombucha are naturally fermented and, when sourced organically, support gut health that may be impacted by glyphosate.
Healthy Fats and Oils: Extra virgin olive oil, cold-pressed avocado oil, and coconut oil are good choices, especially when organic or certified.

Frequently Asked Questions

While certified organic standards prohibit the use of glyphosate, trace amounts can still be found in organic products due to environmental drift from nearby conventional farms. However, organic products consistently show significantly lower levels compared to conventional ones.

Glyphosate can enter food through several pathways, including direct application as a weed killer on crops (especially GMO varieties), use as a drying agent (desiccant) on non-GMO crops like oats, and environmental contamination through wind or water runoff.

Conventional oats, wheat, and barley are high-risk grains because glyphosate is commonly used as a desiccant just before harvest to speed up the drying process. For these grains, it is especially important to choose certified organic or specifically certified glyphosate-free versions.

No. Animals raised on conventional feed, which often contains glyphosate-treated corn and soy, can pass residues into their meat, poultry, or dairy products. Choosing organic, grass-fed, or pasture-raised animal products helps avoid this issue.

Thoroughly washing fruits and vegetables may help remove some surface residues. However, glyphosate is a systemic herbicide, meaning it is absorbed by the plant, so washing alone cannot eliminate all traces.

This is a third-party certification program from The Detox Project. It indicates that a food product has been tested by an accredited lab and contains no detectable glyphosate residues, offering a higher level of assurance than organic certification alone.

The Detox Project maintains a list of brands and specific products that have received its Glyphosate Residue Free certification. Checking their website is a reliable way to find verified products.
