Navigating modern grocery store aisles can be confusing, with a variety of labels promising different production standards. For many, seeking out non-GMO foods is a priority, but knowing how to reliably find them requires knowledge of specific certifications and which ingredients to scrutinize.
Understanding Labels and Certifications
The most straightforward way to identify non-GMO foods is by looking for third-party verification and specific government labels. Not all “non-GMO” labels are created equal, and some standards offer more comprehensive assurances than others.
The Non-GMO Project Verified Seal
This is one of the most widely recognized and trusted certifications for non-GMO products in North America. The verification process involves testing and auditing throughout the supply chain to ensure that ingredients are free from genetic engineering. The iconic butterfly seal indicates that a product has been evaluated for compliance with the Non-GMO Project's standards, including action thresholds for GMO contamination. You will find thousands of products bearing this seal, from fresh produce to packaged goods.
The USDA Organic Seal
All products certified organic by the United States Department of Agriculture (USDA) are also non-GMO, but the certification is much broader. The USDA Organic program prohibits the use of GMOs, but also bans the use of most synthetic pesticides and fertilizers, requires humane animal treatment, and promotes sustainable farming practices. Therefore, choosing organic is a way to ensure non-GMO status while also opting for a more holistic production system. For processed foods, remember that a "Made with Organic Ingredients" label requires at least 70% organic content, but 100% of the ingredients must still be non-GMO.
How to Read PLU Codes
For fresh fruits and vegetables, the Price Look-Up (PLU) sticker can offer clues, though it is not a fail-safe system as labeling is voluntary. A five-digit PLU code beginning with a '9' indicates the item is organic, and therefore non-GMO. A four-digit code signifies conventionally grown produce, which is not genetically modified but may have been grown with pesticides. A five-digit code starting with an '8' denotes a GMO product, but this is a very rare sight as most producers do not volunteer this information.
Aisle-by-Aisle Shopping Strategy
Being a proactive shopper means knowing which foods are most likely to be genetically engineered and how to find non-GMO alternatives in different sections of the store.
Produce Section
This is often the easiest place to avoid GMOs, as fresh, unprocessed fruits and vegetables are the gold standard. Look for organic options or check PLU codes. Some of the most common GMO produce to be aware of includes most non-organic corn, soybeans, and papaya (especially from Hawaii), as well as some zucchini, squash, and new varieties of non-browning apples and potatoes.
Packaged Foods
The highest concentration of GMOs is found in the center aisles of the grocery store, hidden within processed foods. You must be diligent in reading ingredient lists. If you see ingredients from the "High-Risk" list below, check for a Non-GMO Project Verified seal or opt for an organic alternative. Common processed food culprits include cookies, crackers, cereals, dressings, and snacks.
Meat, Dairy, and Eggs
Animal products are also at risk, as most livestock are fed a diet of GMO corn and soy. To ensure your animal products are non-GMO, look for the following:
- Non-GMO Project Verified: Guarantees that the animals were fed a non-GMO diet.
- USDA Organic: Prohibits GMO feed and antibiotics or growth hormones.
- Grass-fed: A strong indicator for cattle, as their diet primarily consists of grass rather than grain feed.
- rBGH/rBST-free: For dairy, this label indicates no genetically engineered growth hormones were used.
High-Risk Crops and Ingredients
Familiarize yourself with the crops and ingredients that are most commonly genetically modified. Unless they are certified non-GMO or organic, consider them high-risk.
- Corn: Corn flour, meal, oil, starch, gluten, and syrup.
- Soy: Soy flour, lecithin, protein, and oils.
- Canola: Canola oil (also known as rapeseed oil).
- Sugar Beets: Found in many products simply listed as "sugar". Always look for "cane sugar" or "evaporated cane juice" to avoid sugar from GMO sugar beets.
- Cotton: Cottonseed oil.
- Aspartame: This artificial sweetener is made using GMO bacterial strains.
The Difference Between Non-GMO and Organic
While related, the non-GMO and organic labels represent different standards. Understanding the distinction is crucial for informed purchasing.
| Feature | Non-GMO Project Verified | Organic Certified (USDA) |
|---|---|---|
| GMO Status | Not genetically modified | Not genetically modified |
| Scope | Single-attribute claim (GMOs only) | Holistic production system |
| Pesticides/Fertilizers | Not regulated | Strictly regulated; synthetic chemicals largely prohibited |
| Animal Welfare | Not regulated | Required standards |
| Sustainability | Not regulated | Part of certification |
| Testing | Quantitative testing for GMO contamination | Qualitative system (inspections, record-keeping) |
All certified organic foods are also non-GMO, but not all non-GMO products are organic. Non-GMO verification solely confirms the absence of genetic engineering, whereas organic certification covers a much broader range of environmental and ethical standards.
Tips for Avoiding GMOs
Here is a list of actionable strategies for your next trip to the store:
- Shop the Perimeter First: Fill your cart with fresh produce, meats, dairy, and eggs from the store's outer perimeter, where you'll find less processed foods.
- Look for the Butterfly: Prioritize products with the Non-GMO Project Verified seal, especially for packaged items and high-risk ingredients.
- Go Organic for High-Risk Items: When a Non-GMO Project Verified seal isn't available for a high-risk product like corn or soy, choose an organic alternative to be safe.
- Buy Local: Many small, local farmers do not use genetically engineered seeds or feed. Visiting a farmers' market and speaking directly with the producer is a great way to source non-GMO foods and support sustainable regional economies.
- Become a Label Detective: Spend time reading the ingredient lists on all packaged foods. Look for the at-risk ingredients and their derivatives.
- Check Supplements: GMOs can even be found in supplements and vitamins, so check for non-GMO verification there as well.
Conclusion
Obtaining non-GMO foods doesn't have to be a confusing or overwhelming task. By understanding the key certification labels like Non-GMO Project Verified and USDA Organic, learning to identify high-risk ingredients, and adopting smart shopping habits, consumers can make confident and informed purchasing decisions. Whether your motivation is for personal health, environmental concerns, or simply a desire for transparency, the power of choice is in your hands.
