According to a study published in Nature, EDTA compounds have the potential to aggravate intestinal inflammation in certain animal models, even at regulated doses. As a common food preservative, this has prompted many to question exactly what foods have EDTA in them and what its role is in the diet.

Quick Summary

This article explores the use of EDTA in the food industry and lists common foods containing this chelating agent. It covers its function, regulated safety levels, and how to identify products with EDTA, offering insights for those mindful of their intake.

Key Points

Chelating Agent: EDTA binds to metal ions like iron and copper, which prevents oxidation and spoilage in processed foods.
Commonly Found: EDTA is prevalent in many processed foods, including canned beans, mayonnaise, salad dressings, and some sodas and alcoholic beverages.
Regulated Safety: In the low concentrations used in food, calcium disodium EDTA is considered safe by regulatory bodies like the FDA and is poorly absorbed by the body.
Potential Concerns: Recent animal studies suggest that EDTA may worsen intestinal inflammation in individuals with pre-existing gut issues, though more human research is needed.
Reduce Exposure: To minimize EDTA intake, prioritize fresh, unprocessed foods, read ingredient labels carefully, and consider making your own condiments from scratch.
Longer Shelf Life: EDTA’s ability to preserve color, flavor, and texture is key to increasing the shelf life of many packaged foods.

What is EDTA and why is it in food?

Ethylenediaminetetraacetic acid (EDTA) is a synthetic compound used as a food additive, most commonly in the form of calcium disodium EDTA. It functions primarily as a chelating agent, which means it binds to metal ions such as iron, copper, and magnesium. In food products, these trace metal ions can trigger oxidation, leading to spoilage, discoloration, and changes in flavor and texture. By binding these metals, EDTA prevents these undesirable chemical reactions, extending the product's shelf life and maintaining its quality and appearance.

The FDA and other regulatory bodies, including the European Food Safety Authority (EFSA), have approved the use of calcium disodium EDTA in food within specific, limited concentrations. This regulatory framework is based on numerous safety studies that have classified the additive as Generally Recognized as Safe (GRAS) for consumption at these low levels. The body absorbs very little of the EDTA found in food, and what is absorbed is then eliminated via urine and feces.

Common foods that contain EDTA

EDTA is found in a wide variety of processed and packaged foods, especially those that are canned, bottled, or jarred for a long shelf life. Common categories of products to check include:

Condiments and Spreads: Mayonnaise, sandwich spreads, and salad dressings frequently contain EDTA to prevent oxidation of fats and oils and to preserve color.
Canned Goods: This includes a range of canned products such as beans and legumes (like pinto and lima beans), vegetables (pickled cabbage, cucumbers), and seafood (clams, shrimp, crab). For canned seafood, it helps prevent the formation of struvite crystals.
Beverages: Certain beverages, including carbonated soft drinks, bottled teas, some fruit juices, and distilled alcoholic beverages, may contain EDTA. In beer, it can be used as an anti-gushing agent.
Processed Fruits and Vegetables: Products like frozen potatoes, canned mushrooms, and dried bananas can have EDTA added to maintain their color and texture.
Dairy Products: While less common, EDTA can be found in some dairy products like cheese spreads and powdered milk to prevent spoilage and maintain consistency.

A closer look at EDTA in your diet

Navigating processed versus whole foods

Understanding where EDTA appears in food products can help in making dietary choices. A comparison highlights the difference between relying on processed items and opting for fresher, whole-food alternatives.


Feature	Processed Foods with EDTA	Whole Foods (EDTA-free)
Shelf Life	Extended due to preservative action.	Shorter; requires refrigeration or timely consumption.
Ingredient List	Long list of ingredients, including 'calcium disodium EDTA' or 'disodium EDTA'.	Simple; ingredients are the natural food items themselves.
Processing Level	High; involves canning, bottling, and various additives.	Low to none; minimally altered from its natural state.
Nutrient Profile	May lose some natural nutrients during processing; sometimes fortified.	Retains natural vitamins and minerals without synthetic additives.
Examples	Canned beans, bottled salad dressing, soda, pre-made mayonnaise.	Fresh beans, homemade vinaigrette, fresh fruit juice, homemade mayonnaise.

Current safety assessments and ongoing research

For most individuals, the amount of EDTA ingested from a typical diet is well within the acceptable daily intake (ADI) levels set by food safety authorities. At these low doses, it is considered safe and is poorly absorbed by the body. However, some groups have raised concerns, particularly regarding potential interactions in specific health conditions.

For example, recent animal studies on inflammatory bowel disease (IBD) models have indicated that EDTA may disrupt the intestinal barrier and exacerbate inflammation, even at levels previously considered safe. While human data is limited, this research suggests that individuals with pre-existing gut inflammation might be more susceptible to adverse effects. Furthermore, while rare, some have raised theoretical concerns that very high levels of EDTA could potentially chelate essential minerals like zinc, though this is not a concern at typical food-use levels.

How to minimize dietary exposure

For those seeking to limit their intake of food additives like EDTA, adopting a whole-food-centric diet is the most effective strategy. This involves prioritizing fresh, unprocessed foods over packaged and canned items.

Choose Fresh Over Canned: Opt for fresh or frozen vegetables and legumes instead of their canned counterparts. Fresh seafood is also a great alternative to canned fish and shellfish.
Make Your Own Condiments: Prepare homemade salad dressings and mayonnaise from scratch to have full control over the ingredients. A simple vinaigrette can be made with oil, vinegar, and fresh herbs.
Read Labels Carefully: Always check the ingredient list on packaged foods, condiments, and drinks. Look for “calcium disodium EDTA” or similar terms. The Environmental Working Group (EWG) also provides a database to check product ingredients online.
Consider Drink Alternatives: Replace sodas and sweetened, bottled beverages with water, homemade juices, or unsweetened teas to avoid additives.

Conclusion

While regulatory bodies classify calcium disodium EDTA as safe for consumption at low, controlled levels, it is most prevalent in processed and packaged foods rather than whole, nutrient-dense foods. Its primary purpose is to extend shelf life and preserve the aesthetic qualities of products by binding to trace metal ions. Concerns have been raised, especially for those with existing inflammatory gut conditions, based on limited animal studies. Ultimately, for those prioritizing a diet with fewer additives, understanding what foods have EDTA in them empowers you to make informed choices. Focusing on fresh, whole foods and making your own condiments are practical steps to reduce exposure while maintaining a healthy diet.

Frequently Asked Questions

In food, the form used is almost always calcium disodium EDTA, which is considered safer than disodium EDTA. The added calcium prevents the additive from depleting calcium from the body at high doses.

Regulatory agencies consider the low levels of EDTA used in food to be safe for the general population. It is poorly absorbed by the body. However, high doses, as used in medical chelation therapy, can cause significant side effects.

At the very high doses found in medical chelation therapy, EDTA can bind to essential minerals like zinc, leading to potential deficiencies. At the much lower levels found in processed food, this effect is not considered significant.

For most healthy people, the regulated levels of EDTA in food are not a concern. However, recent animal studies suggest potential risks for individuals with pre-existing intestinal inflammation, and those with specific sensitivities or medical conditions should consult a healthcare professional.

To check for EDTA, you should read the ingredient list on packaged foods. It will be listed as 'calcium disodium EDTA', 'disodium EDTA', or by its European food additive number 'E385'.

In canned seafood, EDTA helps to prevent the formation of struvite crystals (a natural component of fish) that can appear like broken glass. It also helps to prevent discoloration.

No, not all processed foods contain EDTA. It is added to specific products to address issues with color, flavor, texture, and shelf life. Checking the ingredient label is the only way to know for sure.
