Have you ever felt bloated, fatigued, or mentally foggy after eating foods everyone says are healthy? You eat salads, whole grains, and lean proteins, yet something still feels off. Your doctor runs standard allergy tests. Everything comes back negative. You are told nothing is wrong.
Have you ever felt bloated, fatigued, or mentally foggy after eating foods everyone says are healthy? You eat salads, whole grains, and lean proteins, yet something still feels off. Your doctor runs standard allergy tests. Everything comes back negative. You are told nothing is wrong.
AgeRejuvenation in Tampa understands what traditional medicine misses. Your body might be fighting foods you have eaten your entire life. These are not dramatic allergic reactions with hives or throat swelling. They are quiet, systemic inflammation responses that slowly drain your energy, cloud your thinking, and prevent optimal health.
We measure both IgG and IgA antibody responses to over 200 common foods, mapping exactly which foods trigger your immune system. No guesswork. No restrictive elimination diets based on trends. Just personalized data showing what your body actually needs.

Why Standard Allergy Testing Misses Food Sensitivities
Answer: Most conventional allergy tests measure IgE antibodies, the immune proteins responsible for immediate reactions like hives and anaphylaxis. Food sensitivities involve IgG and IgA antibodies instead, which trigger delayed inflammatory responses that appear 24 to 72 hours after eating the trigger food. This delayed timeline makes them nearly impossible to identify through observation. According to research published in clinical nutrition literature, IgG-mediated food sensitivities affect a meaningful portion of the population and contribute to chronic conditions that conventional medicine attributes to other causes, including IBS, eczema, chronic fatigue, and brain fog.
This is why you feel fine Monday morning but exhausted and unfocused Tuesday afternoon. You never connect Tuesday's symptoms to Sunday's dinner because the window is too wide. Standard allergy testing misses these delayed reactions entirely because it is designed to find the wrong immune mechanism.

Conditions We Help Identify with Food Sensitivity Testing
Food sensitivities, when unaddressed, contribute to a range of conditions that most patients are treating separately and ineffectively.
Chronic Digestive Symptoms and IBS
Unresolved IgG food reactions create persistent gut inflammation that mimics IBS exactly: bloating, alternating bowel habits, cramping, and discomfort. Many patients diagnosed with IBS carry unidentified food sensitivities as the primary driver. Identifying and eliminating trigger foods allows the gut lining to heal. This connects directly to the gut inflammation we treat at our Tampa clinic.
Brain Fog and Cognitive Difficulty
Neurological symptoms are among the least expected presentations of food sensitivity. Chronic low-grade inflammation from reactive foods impairs neurotransmitter function and contributes to the mental fatigue, concentration difficulty, and mood instability patients describe as brain fog.
Skin Conditions
Eczema, acne, rosacea flares, and unexplained hives are frequently driven by food-triggered immune responses. The gut-skin axis means that intestinal inflammation from food reactions surfaces visibly on the skin before most patients recognize the connection.
Weight Gain Resistance and Metabolic Disruption
Chronic immune activation from food sensitivities elevates inflammatory cytokines that interfere with insulin sensitivity, cortisol regulation, and fat storage signals. Patients who cannot lose weight despite appropriate diet and exercise sometimes discover a food sensitivity as the hidden variable.
Persistent Fatigue and Energy Instability
The body's immune response to food triggers consumes metabolic resources. Patients report significant, sustained improvement in energy after eliminating high-reactivity foods, particularly when the reaction previously appeared as post-meal fatigue.
Advantages of Comprehensive IgG/IgA Testing at AgeRejuvenation
Testing 200+ Foods Simultaneously
Standard elimination diets remove entire food groups for weeks, hoping to identify triggers through trial and error. This process takes months, requires extreme discipline, and yields inconclusive results far too often. Our panel tests your blood against 200-plus foods simultaneously, covering grains, dairy, proteins, vegetables, fruits, nuts, seeds, spices, and additives. Your personalized report categorizes foods into reactivity levels: high, moderate, and non-reactive.
Comprehensive Nutritional Counseling Included
Your food sensitivity results consultation is not a lab report printout. Our practitioners review findings with you, identify safe replacement foods, explain reactivity patterns, and create customized elimination protocols with meal planning guidance and shopping lists. Tampa patients appreciate the practical, livable approach.
Reintroduction Protocol for Maximum Dietary Freedom
After elimination periods, we guide strategic reintroduction to determine whether sensitivities resolve with gut healing or require permanent avoidance. Most patients reintroduce moderate-reactivity foods successfully after 12-16 weeks. The goal is maximizing the range of foods you can enjoy while eliminating those causing harm.
Connection to Root-Cause Functional Medicine
Food sensitivity testing does not exist in isolation at AgeRejuvenation. We correlate results with inflammatory markers, gut health data (GI-MAP stool testing), and hormone balance to create comprehensive protocols addressing the interconnected root causes of your symptoms.
Why Choose AgeRejuvenation for Food Sensitivity Testing in Tampa?
AgeRejuvenation combines validated laboratory testing with comprehensive patient education. We interpret findings within the context of your complete health picture, gut microbiome status, and inflammation patterns, not just the food reactivity list.
Our Tampa location at 220 North Howard Ave serves patients from the 33606 zip code, Brandon (33511), Wesley Chapel (33544), and extending to the Orlando area. Residents of South Tampa, Westshore, and surrounding areas who deal with Tampa's subtropical allergen load and high humidity already have a heightened immune burden. Unresolved food sensitivities layer additional inflammation on top.
