Food Sensitivity Tests are BS - What Matters More?

Have you ever found yourself saying:

"I used to eat this all the time, but now it makes me feel terrible."

Maybe it's dairy.
Maybe it's gluten.
Maybe it's eggs, nuts, coffee or even healthy foods like broccoli and avocados.

One day they seemed fine. The next, you're dealing with bloating, stomach pain, headaches, fatigue, skin issues, brain fog, digestive discomfort, or inflammation.

And naturally, you start wondering:
"What food do I need to eliminate next?"
But what if the food isn't actually the problem?

Food sensitivities are often a symptom, not the root cause. In many cases, they're simply a signal that something deeper is happening.

When the gut lining becomes compromised and the immune system is stuck in a heightened state of alert, foods that were once tolerated can suddenly begin triggering symptoms.

The food didn't necessarily change.
Your body's ability to tolerate it did.

This is why so many women find themselves trapped in a frustrating cycle:

  • Eliminate a food

  • Feel better temporarily

  • Reintroduce the food

  • Symptoms return

  • Eliminate another food

  • Repeat

Months - or even years - later, they have a growing list of foods they avoid, but they still don't feel well.
The reason? The underlying terrain has never been addressed - meaning the gut AND the immune system.

Did you know that approximately 70-80% of your immune system resides within and around your gut?

Think about that for a moment.

Your digestive system isn't just responsible for breaking down food. It's also one of the body's primary communication centers for immune function. So when the gut barrier becomes compromised - often referred to as increased intestinal permeability or "leaky gut" - larger particles can pass through the intestinal lining and interact with the immune system.

Then - the immune system responds the way it was designed to respond:
It becomes activated.

But over time, that heightened immune response over and over can contribute to increased sensitivity and reactivity, creating symptoms that seem to be caused by food but are actually rooted in a stressed, overwhelmed, overactive system.

So - why does this happen? There isn't usually one single cause. More often, it's the accumulation of multiple stressors over time. Common contributors include:

  • Chronic stress

  • Poor sleep

  • Blood sugar dysregulation

  • Frequent alcohol consumption

  • Nutrient deficiencies

  • Environmental toxins and chemicals

  • Gut infections or microbial imbalances

  • Digestive dysfunction

  • Hormonal imbalances

  • Excessive inflammation

Eventually, the body reaches a point where its resilience decreases and symptoms begin to appear. The food often gets blamed. But it's usually just exposing the problem.

So instead of diving into the rabbit hole of food sensitivity tests (that will keep you stuck in circles) - focus on creating an internal environment that supports healing and resilience.

Things like…

1. Support Gut Integrity

A healthy gut lining is essential for proper digestion, nutrient absorption, immune regulation, and overall wellness. Start by supporting:

  • Stomach acid production

  • Digestive capacity

  • Nutrient absorption

  • Gut barrier function

  • Healthy bowel movements

Supportive tools may include:

  • L-Glutamine

  • MegaIgG

  • Digestive enzymes

  • Proper hydration

  • Thorough chewing

  • Slowing down during meals

Remember, digestion starts before food even enters your stomach. Creating calm around meals matters.

2. Calm the Immune System

An immune system that is constantly under pressure becomes reactive. This is where reducing inflammatory inputs becomes important. Focus on:

  • Improving sleep quality

  • Supporting Vitamin D levels

  • Reducing alcohol consumption

  • Minimizing exposure to unnecessary chemicals

  • Addressing infections when present

  • Stabilizing blood sugar

The goal is to help return the immune system to a better balance and more resiliency.

3. Reduce the Overall Stress Load

Your body doesn't distinguish between physical stress and emotional stress. To your nervous system, lack of sleep, overtraining, financial stress, caregiving demands, blood sugar crashes and relationship conflict all contribute to the same stress bucket. When that bucket overflows, symptoms often increase.

Simple practices can make a significant difference:

  • Daily walks

  • Consistent sleep and wake times

  • Time outdoors

  • Prayer or meditation

  • Breathwork

  • Healthy boundaries

  • Magnesium support

Sometimes the most powerful healing tools are the least glamorous.

4. Address the Root Cause

The most important question isn't:
"What food should I remove next?"

The better question is:
"Why is my body reacting in the first place?"

When we begin asking that question, the conversation shifts. We stop chasing symptoms. We stop fearing food. We stop relying on guesswork. And we start uncovering the deeper factors influencing gut health, immune function, hormones, metabolism, stress resilience and overall wellness.

Remember - your body is MEANT to heal! A healthy body should be adaptable. A healthy immune system should be responsive, not reactive. And a healthy gut should help you nourish your body - not make you afraid to eat foods.

This is one of the core concepts I teach inside my coaching program. Together, we look beyond symptoms and begin connecting the dots between gut health, immune function, hormones, metabolism, nutrition, lifestyle, stress and the unique story your body is telling. Because the answer isn't always found in eliminating another food. Often, it's found in understanding why your body lost tolerance in the first place and giving it the support it needs to rebuild resilience.

If this resonates with you, I recently shared more on this topic in my Instagram post discussing why food sensitivities are often symptoms of a larger conversation happening inside the body.

The goal isn't restriction. The goal is restoration!!
