For many consumers, knowing how to find non-GMO foods is a top priority. Genetically modified organisms (GMOs) are created by altering an organism's genetic material in a laboratory setting. While the safety of GMOs is a subject of ongoing debate, the demand for non-GMO options has led to various labeling programs designed to help shoppers make informed decisions. By understanding these labels, knowing which ingredients are high-risk, and adopting smart shopping habits, you can confidently navigate the grocery store aisles.
Deciphering Non-GMO Food Labels
One of the most direct ways to ensure you are buying non-GMO products is to understand and recognize credible certifications. Third-party organizations have established standards to verify products that are produced without genetic engineering.
-
The Non-GMO Project Verified Seal: This distinctive butterfly label is one of the most widely recognized non-GMO certifications in North America. Products with this seal have undergone a third-party verification process to ensure they meet the Non-GMO Project's rigorous standards for avoiding GMOs. The standard requires traceability, segregation, and testing of high-risk ingredients.
-
USDA Certified Organic: Federal organic regulations explicitly prohibit the use of GMOs. Therefore, any product bearing the official USDA Organic seal is, by definition, non-GMO. The organic certification process is a holistic one that also prohibits the use of synthetic pesticides, fertilizers, and antibiotics in livestock. This means that while all certified organic products are non-GMO, not all non-GMO products are organic.
-
Bioengineered Label (Mandatory): In the U.S., a mandatory labeling standard requires food manufacturers to disclose if a product contains bioengineered (BE) ingredients. This can appear as a small text or seal, but it's important to note that many companies have sought third-party verification, like the Non-GMO Project, to provide more detailed assurance beyond this basic requirement.
The High-Risk Ingredient List
Processed and packaged foods carry a higher risk of containing genetically engineered ingredients, especially if they are not certified non-GMO. Becoming familiar with the most common GMO crops can help you spot potential GMOs on ingredient lists.
The Most Common GMO Crops and Their Derivatives
- Corn: Found in many forms, including corn oil, high-fructose corn syrup, corn starch, and corn meal.
- Soy: Used widely in processed foods as soy oil, soy lecithin, soy flour, soy protein, and more.
- Canola: Almost all canola oil is derived from genetically engineered crops unless it's explicitly labeled otherwise.
- Sugar Beets: Much of the sugar used in processed foods and beverages is derived from genetically modified sugar beets. Look for "cane sugar" or "organic sugar" to avoid this risk.
- Cotton: Cottonseed oil is often used in processed foods.
- Alfalfa: Commonly used as feed for livestock.
- Papaya: Most Hawaiian papaya is genetically modified, so look for organic or non-GMO labeled varieties.
Comparison of Non-GMO Certification Standards
To help clarify the differences between the two primary non-GMO labels, here is a comparison of their focus and requirements.
| Feature | Non-GMO Project Verified | USDA Certified Organic |
|---|---|---|
| Scope | Focuses exclusively on GMO avoidance. | Holistic program covering production, handling, and processing. |
| Testing | Requires rigorous testing of high-risk ingredients to ensure GMO levels are below 0.9%. | Does not require testing for GMOs but prohibits their use as an "excluded method". |
| Coverage | Applicable to all eligible products, including food, personal care items, and textiles. | Covers agricultural products, including produce, meat, dairy, and processed foods with 95%+ organic ingredients. |
| Accidental Contamination | Has an established "action threshold" of 0.9% for contamination and requires measures to prevent it. | Assumes producers will avoid GMOs but lacks specific testing mechanisms for contamination, though it is still disallowed. |
| Other Inputs | Does not regulate pesticide or antibiotic use, or other farming practices. | Prohibits synthetic pesticides, fertilizers, antibiotics, and growth hormones. |
Practical Steps for Shopping Non-GMO
-
Focus on Whole Foods: Prioritize fresh fruits, vegetables, grains, and meats. Most produce, aside from high-risk crops like corn and papaya, is not genetically modified. By cooking and preparing meals with whole ingredients, you can avoid many packaged products where GMOs hide.
-
Shop Locally: Visit your local farmers' markets and get to know the producers. Small, local farms are less likely to grow genetically modified crops and are often happy to discuss their farming practices with you. This also supports your local economy and reduces your carbon footprint.
-
Know Your Dairy and Meat: For animal products, look for labels like "grass-fed," "wild-caught," or certified non-GMO. Much of the soy and corn that goes into animal feed is genetically modified, so these certifications can provide extra assurance. Dairy labeled "r-BGH/rBST-free" indicates that cows have not been given the genetically engineered growth hormone.
-
Use Non-GMO Shopping Guides: Several non-profit organizations offer shopping guides and searchable databases to help consumers find verified non-GMO products. The Non-GMO Project's website is a valuable resource for identifying verified items.
-
Buy Non-GMO for High-Risk Items: For processed foods that are difficult to avoid, specifically seek out versions that carry a non-GMO label, particularly if they contain corn, soy, canola, or beet sugar. This includes items like cereals, bread, sauces, and cooking oils.
Conclusion
Finding non-GMO foods can be as simple as looking for trusted labels like the Non-GMO Project Verified butterfly or the USDA Organic seal. For shoppers who want to go further, focusing on whole foods, shopping locally, and being aware of high-risk ingredients in processed products are effective strategies. While both organic and non-GMO labels provide assurance, understanding the nuances—particularly that all organic is non-GMO, but not all non-GMO is organic—allows you to make the most informed choices for your diet. By using these tools and tips, you can reclaim control over what's in your food and support the production of non-genetically modified ingredients.
