Food Allergies: Why Gut Health is Key

by Susanne  - August 11, 2025

Food allergies can feel frustrating, limiting, and sometimes downright overwhelming. While traditional testing and treatments can help identify and manage specific triggers, they often overlook the root of the problem: the health of your gut.
The gut is not just about digestion—it’s a master control center for the entire body. It influences immunity, inflammation, mood, and even brain function through the gut-brain connection (Johns Hopkins Medicine). When the gut is compromised, your entire body feels the impact.

How Our Gut Health Gets Damaged
Almost all of us have taken antibiotics at some point in our lives. While sometimes necessary, antibiotics can wipe out beneficial gut bacteria along with harmful ones (Harvard Health). Beyond prescriptions, antibiotics are also commonly used in livestock feed for chickens and cattle, meaning we’re consuming them indirectly through food.

Another hidden culprit is glyphosate—the active ingredient in the herbicide RoundUp. While primarily used to control weeds, glyphosate is also patented as an antimicrobial agent (U.S. Patent No. 7771736), meaning it can disrupt beneficial gut microbes. Glyphosate is widely used in agriculture and is present throughout our food supply—including on produce, fruits, vegetables, and in the grains fed to livestock. This means we’re exposed not only through plant foods but also through meat and dairy from animals that have consumed it. Combine these factors with the Standard American Diet—highly processed, nutrient-poor, and full of additives—and it’s no wonder gut health, and by extension immune health, suffers.

Why Processed Foods Make It Worse
A diet high in refined carbs, added sugars, and chemical additives fuels the growth of harmful microbes while starving beneficial bacteria of the prebiotic fiber they need to thrive. Sugar in particular feeds bacteria and yeast species that disrupt the balance of the gut microbiome, which can increase inflammation and worsen allergy symptoms (Harvard T.H. Chan School of Public Health).

Supporting the Gut for Fewer Allergy Symptoms
If allergies are making life difficult, start with your gut:

  • Add prebiotic fiber from vegetables, fruits, and whole foods to feed beneficial microbes (National Institutes of Health).
  • Eat probiotic-rich foods like kefir, yogurt with live cultures, sauerkraut, and kimchi.
  • Reduce sugar and processed foods to limit harmful microbial overgrowth.
  • Choose whole, nutrient-dense foods to nourish your body at the cellular level.

There are also natural remedies and supplements that can help reduce harmful microbes and support the process of rebuilding healthy ones. These can include targeted herbal antimicrobials, specific probiotic strains, and nutrients that help heal and strengthen the gut lining. Choosing the right approach is highly individual—and something I can help you with so your plan is effective, safe, and sustainable.

It’s Not Just About Avoiding Foods
Identifying and avoiding problem foods can help in the short term—but long-term relief often comes from rebuilding gut health from the inside out. This means shifting the terrain so your body can respond more appropriately to potential triggers.
