Citric acid is a ubiquitous ingredient in processed foods, found in everything from beverages and condiments to candies and baked goods. While it naturally occurs in citrus fruits, the citric acid in most packaged foods is not derived from these fruits.
Instead, it’s produced through fermentation using Aspergillus niger, a mold that is often genetically modified to improve efficiency and reduce production costs. Many don’t realize that this ingredient, though generally recognized as safe by food authorities, is actually derived from a potentially toxic GMO mold and not from natural citrus sources.
How Industrial Citric Acid Is Made
The commercial production of citric acid uses the mold Aspergillus niger, which is grown on a sugar source (often derived from GMO corn). This mold ferments the sugar, yielding citric acid as the primary product. To maximize yield, strains of Aspergillus niger have been genetically modified. Although this method is efficient and has a lower cost for food production, some are concerned about the presence of residual byproducts from the mold, as well as any potential health effects related to genetic modification.
Why Use Mold in Production?
Producing citric acid directly from citrus fruits is far too costly and labor-intensive to meet industrial demands, so companies use Aspergillus niger as a more economical and scalable solution. While the U.S. Food and Drug Administration (FDA) has labeled citric acid produced in this way as "Generally Recognized As Safe" (GRAS), this designation primarily assesses acute safety and not long-term health impacts.
Potential Health Concerns with Citric Acid and Mold Exposure
While most people tolerate citric acid in small amounts, overconsumption, especially from industrial sources like Aspergillus niger, can increase health risks over time. Those with mold sensitivities or weakened immune systems may be particularly susceptible to adverse reactions, but even individuals without known sensitivities could experience health issues from high exposure. Regular intake of citric acid through processed foods may contribute to digestive discomfort, skin issues, or even inflammatory responses, as the body accumulates exposure to this additive. Being mindful of consumption levels and choosing whole, minimally processed foods can help reduce potential health impacts.
Here are some areas of concern:
Allergic Reactions and Sensitivities For individuals with mold allergies, even slight traces of mold-related byproducts could trigger reactions. Symptoms might include digestive upset, skin rashes, joint pain, or respiratory issues. It’s essential to read labels carefully if you are sensitive to mold or certain food additives.
Mold Exposure Mold exposure in general can lead to a range of symptoms, including fatigue, headaches, respiratory issues, and cognitive problems. For those with mold allergies or sensitivities, mold byproducts can exacerbate these symptoms, even if exposure is indirect. With food-grade citric acid derived from mold, some may experience symptoms similar to mold exposure, especially if they have a heightened sensitivity.
Inflammatory Responses While conclusive studies are limited, it’s suggested that some individuals may experience inflammation as a response to citric acid. People with autoimmune disorders or chronic inflammation may want to monitor their response to citric acid in processed foods and, if necessary, avoid it.
Symptoms of Mold SensitivityMold sensitivity can present with a range of symptoms, including:
Respiratory issues like coughing or wheezing
Skin rashes or itching
Digestive discomfort or bloating
Fatigue and brain fog
Joint pain or muscle aches
Eye irritation and sinus congestion
If you experience any of these symptoms after consuming processed foods high in citric acid, it may be worth considering whether this additive is a trigger.
Reading Labels to Avoid Processed Citric Acid
It is best to read labels carefully and avoid products with industrial citric acid whenever possible, as every individual’s biochemistry is unique and functions like its own ecosystem. What one person may tolerate without issue could cause reactions in another, especially with frequent exposure. Opting for whole, minimally processed foods not only helps reduce intake of unnecessary additives but also supports the body’s unique balance and health needs. Taking this extra step can be a proactive way to protect your well-being in the long term.
Citric acid is an additive in many processed foods, so it’s essential to check ingredient lists if you’re concerned about mold exposure. Choose products labeled “organic” or opt for fresh, whole foods that don’t contain this additive. Fresh fruits, vegetables, and minimally processed foods are less likely to contain industrial citric acid.
Making Informed Choices About Citric Acid
Choose Whole Foods Fresh fruits and vegetables are naturally free from additives like citric acid. Preparing meals from whole ingredients can help you avoid exposure to unnecessary additives.
Look for Organic Labels Organic products are less likely to contain additives derived from genetically modified sources. Though not all organic foods are citric acid-free, reading labels helps you avoid genetically modified additives.
Consult a Healthcare Provider If you experience adverse symptoms after consuming foods with citric acid, speak to a healthcare professional. They can help identify sensitivities and suggest dietary changes to improve your health.
In my humble opinion, and as many of my clients know, I'm a bit of a nerd when it comes to understanding ingredients that seem harmless but can lead to unresolved health issues. Clearing out toxins is essential, especially in the highly toxic world we live in. It’s so important to work with someone who genuinely cares and takes the time to look at what you’re eating and how it might be affecting your health.
