According to a 2018 report by the Environmental Working Group (EWG), 100% of conventional oat-based products tested contained residues of the herbicide glyphosate. If you're wondering what brand of oats are clean, understanding the difference between conventional, organic, and certified-pure options is crucial for making a healthy, informed decision for your diet.

Quick Summary

This article defines what constitutes 'clean' oats, focusing on farming practices, pesticide avoidance, and cross-contamination prevention. It identifies reputable brands committed to producing organic, glyphosate-free, or purity-protocol certified oats and offers a comparison to help consumers select the best product for their nutritional needs.

Key Points

Organic is the Safest Bet: For a significant reduction in pesticide exposure, always choose oats with a USDA Organic certification.
Glyphosate-Free Certification for Highest Assurance: To guarantee no glyphosate residue, look for brands with a 'Glyphosate Residue Free' certification from independent third parties like The Detox Project.
Purity Protocol for Celiac Safe Oats: Individuals with celiac disease should seek out oats certified gluten-free via 'Purity Protocol' to avoid cross-contamination from other grains.
Less Processed Means Fewer Additives: Steel-cut and old-fashioned rolled oats are typically cleaner and contain fewer additives than heavily processed instant oats.
Check for Hidden Ingredients: Always read the ingredients list, especially on instant or flavored oatmeal, to avoid hidden sugars, artificial flavors, and preservatives.
Brand Transparency is Key: Brands that are transparent about their sourcing, farming, and processing practices, like One Degree Organic Foods, offer greater peace of mind.

Defining 'Clean' Oats

The term 'clean' isn't an official certification, but in the context of oats, it refers to products that are free from unwanted chemical residues and contaminants. When consumers search for 'clean oats,' they are typically looking for options grown without synthetic pesticides like glyphosate and processed in a way that minimizes cross-contamination. Oats are naturally gluten-free, but cross-contamination can occur if they are processed in facilities that also handle gluten-containing grains like wheat and barley. This is why certain certifications are so important.

The Controversial Use of Glyphosate

Glyphosate is a widely used herbicide, famously known as the active ingredient in Roundup. Farmers often use it as a pre-harvest desiccant to dry out crops like oats, allowing for an earlier and more uniform harvest. This practice, however, leads to significant glyphosate residue in the final product. For years, the EWG has highlighted the presence of glyphosate in popular oat brands, linking it to potential health concerns. While recent tests show a decline in some products, the chemical is still found in many conventional offerings. For many, avoiding this chemical is a key reason for seeking 'clean' oats.

Understanding the Purity Protocol

For individuals with celiac disease or gluten sensitivity, the risk of cross-contamination is a major concern. Purity Protocol is a rigorous standard for producing gluten-free oats. It involves strict controls throughout the entire process, including:

Dedicated Fields: Oats are grown in fields that have not planted gluten grains for several years.
Dedicated Equipment: Farmers use specialized equipment for harvesting and transportation to prevent agricultural co-mingling.
Dedicated Facilities: The oats are milled and processed in dedicated gluten-free facilities.
Rigorous Testing: Products are consistently tested to ensure they meet certified gluten-free standards (typically less than 20 ppm of gluten).

This method offers the highest assurance of a truly gluten-free product, a crucial aspect of clean eating for many.

Leading Brands for Clean and Pure Oats

Several brands are known for their commitment to producing clean oats, using organic farming methods or strict purity protocols. Here are some of the top contenders:

Bob's Red Mill: This brand offers both conventional and organic options, and their certified gluten-free oats are processed under strict purity protocol standards. Their Organic Old-Fashioned Rolled Oats are a popular choice for those prioritizing organic ingredients.
Nature's Path: Another long-standing organic food producer, Nature's Path offers a range of certified organic oatmeals and granolas, free from synthetic pesticides and GMOs. They are a reliable option for consumers focused on organic sourcing.
One Degree Organic Foods: This brand goes a step further by using sprouted oats and ensuring all products are both USDA Organic and Glyphosate Residue Free certified. They provide complete transparency, allowing you to trace the oats back to the farm.
Back Roads: A pioneer in the Glyphosate Residue Free space, Back Roads was one of the first companies to get certified by the Detox Project. They offer organic, kosher, and gluten-free options, focusing on whole and natural ingredients.
Bakery on Main: This brand's products, including their oatmeal cups, often utilize oats sourced from purity protocol suppliers like Avena Foods. They are also certified gluten-free, providing a clean and convenient option.

Comparison of Oat Types and Brands

To make your choice easier, this table compares popular oat options based on processing, certifications, and overall 'cleanliness':


Feature	Conventional Oats (e.g., standard Quaker)	Organic Oats (e.g., Quaker Organic)	Certified 'Clean' Oats (e.g., One Degree Organic)
Pesticide Risk	High risk of glyphosate and other herbicide residues due to pre-harvest spraying.	Minimal risk, but potential for trace cross-contamination from drift.	Very low risk; certified Glyphosate Residue Free or Purity Protocol offers high assurance.
Processing	Varies; quick and instant oats are pre-cooked and dried, often with added sugars and preservatives.	Varies; offers rolled, instant, and steel-cut organic options.	Varies; available in different forms (rolled, sprouted) with a focus on purity.
Gluten Contamination	High risk due to potential for agricultural co-mingling and processing alongside gluten grains.	Reduced risk but not guaranteed; a dedicated gluten-free label is needed for certainty.	Negligible risk; processed under strict Purity Protocol to prevent cross-contact.
Sourcing	Typically large-scale, conventional farming with less transparency.	Certified organic farming methods, which exclude synthetic pesticides.	Often involves a high degree of transparency and close relationships with growers.

How to Choose the Right Oats for You

Your personal health goals and dietary requirements will determine which oats are best for you. Here are some steps to guide your choice:

Prioritize Organic: If your primary concern is avoiding synthetic pesticides and GMOs, look for a USDA Organic label. This is a robust first step towards ensuring your oats are clean.
Look for Specific Certifications: For the highest assurance, seek out specific labels like 'Certified Glyphosate Residue Free' (by The Detox Project) or a 'Certified Gluten-Free' label that specifies 'Purity Protocol' if you have celiac disease.
Choose Less Processed Oats: Steel-cut or old-fashioned rolled oats are less processed than instant oats. They are often purer and offer more texture, with fewer additives. This is a good way to ensure you're getting a simple, whole-grain product.
Read the Ingredient List: Always check the ingredient list, especially with instant or flavored oatmeals. Many contain added sugars, artificial flavors, and other additives that detract from the 'clean' eating experience. A truly clean oat product will have a single ingredient: oats.
Consider the Source: Brands that are transparent about their sourcing and processing methods often provide higher quality products. Brands like One Degree Organic Foods allow you to trace the source of your oats, which provides great peace of mind.

Conclusion: Making an Informed Choice

In the end, what defines a 'clean' brand of oats depends on what you prioritize: a pesticide-free product, guaranteed gluten-free status, or minimal processing. While conventional brands like Quaker have improved in some respects, certified organic, glyphosate-free, or purity-protocol options from brands like Bob's Red Mill, Nature's Path, One Degree Organic, and Back Roads provide the highest level of assurance. By understanding the certifications and reading labels carefully, you can confidently choose the purest, healthiest oats for your nutritional needs and diet.

Frequently Asked Questions

The main difference lies in the farming methods. Organic oats are grown without synthetic pesticides, herbicides, or fertilizers. Conventional oats, in contrast, often use these chemicals, including glyphosate, which is sometimes applied just before harvest.

Not necessarily. While organic farming prohibits the use of glyphosate, trace amounts can still be present due to environmental drift from nearby conventional farms. For the highest assurance of no glyphosate, look for an additional 'Glyphosate Residue Free' certification.

Oats are naturally gluten-free but are often grown or processed alongside gluten-containing grains like wheat, barley, and rye. This can lead to cross-contact, making conventional oats unsafe for individuals with celiac disease or gluten sensitivity.

Purity Protocol is a stringent standard that ensures oats are grown, harvested, and processed in a way that eliminates cross-contamination with gluten-containing grains. This provides the highest level of safety for gluten-sensitive consumers.

Instant oats are more processed and pre-cooked, often containing additives, preservatives, and high levels of sugar, which can make them less clean than steel-cut or old-fashioned rolled oats.

To find truly glyphosate-free oats, look for products that are both certified USDA Organic and have the 'Glyphosate Residue Free' label from The Detox Project. One Degree Organic Foods is an example of a brand that carries this certification.

Look for a USDA Organic seal, a Certified Gluten-Free label (ideally Purity Protocol), and, for ultimate assurance, a Glyphosate Residue Free certification. Always read the ingredient list for any unwanted additives.
