Discover how food sensitivity testing through Aligned Modern Health helps uncover dietary triggers behind fatigue, inflammation, and digestive symptoms. Available statewide across Missouri through Functional Medicine and Virtual Care.
If you have persistent bloating, brain fog, fatigue, or skin irritation, certain foods may be quietly stressing your system. Food sensitivity testing identifies delayed immune or inflammatory responses that can affect energy, mood, and digestion.
Aligned Modern Health provides Functional Medicine food sensitivity testing across Missouri, serving patients in St. Louis, Kansas City, Springfield, Columbia, St. Charles, and surrounding communities through in-person care and Virtual Care.

“When patients understand the ‘why’ behind their reactions, it changes everything. Food sensitivity testing helps connect daily habits to underlying inflammation so we can build a plan that truly fits their body.”
— Dr. Blake Butler, Functional Medicine Physician
Unlike food allergy testing, which detects immediate immune responses, food sensitivity testing reveals delayed reactions that may appear hours or days after eating. These hidden sensitivities can contribute to digestive distress, fatigue, headaches, and inflammation. Our Missouri Functional Medicine providers use data-driven testing to create personalized plans that integrate nutrition, hormone balance, and gut health—addressing root causes rather than masking symptoms.
| Condition | What Happens in the Body | Typical Symptoms |
|---|---|---|
| Food Allergy | Immediate immune reaction (IgE) | Hives, swelling, or anaphylaxis |
| Food Sensitivity | Delayed immune response (often IgG-mediated) | Bloating, fatigue, joint pain, headaches |
| Food Intolerance | Digestive enzyme deficiency or chemical reaction | Gas, cramping, diarrhea (e.g., lactose intolerance) |
Each condition involves different biological mechanisms. Comprehensive testing helps identify whether symptoms stem from immune, digestive, or inflammatory pathways.
“Testing gives patients a clear roadmap for change. Once we know which foods are creating stress, we can focus on healing the gut, reducing inflammation, and helping the body regain its natural balance.”
— Dr. Blake Butler, Functional Medicine Physician
A simple blood draw measures immune reactivity to dozens of foods. IgG and IgA antibodies reflect delayed or digestive immune responses that can indicate food sensitivities and diet-related inflammation, rather than true food allergies (which involve IgE antibodies).
Structured removal and reintroduction to confirm which foods drive your symptoms and guide lasting dietary changes.
Useful as a starting point; professional interpretation ensures accuracy and a targeted plan.
Evaluates how your genes influence nutrient metabolism, inflammation, and immune tolerance to personalize care.
Typical foods analyzed include:
Your results are interpreted within the context of gut health, hormones, and inflammation to identify true drivers and guide next steps.
