Food Sensitivity Testing in Las Vegas
You eat something and feel terrible — bloated, tired, foggy, or broken out — but you can't figure out what it is. You cut out gluten. Then dairy. Then everything fun. Nothing clearly helps, and eating starts to feel like a minefield.
The problem isn't you. It's that guessing doesn't work. At Vital Fit in Las Vegas, food sensitivity testing identifies exactly which foods your body is reacting to — so you can stop eliminating everything and start eating with confidence.
Sensitivity vs. Allergy vs. Intolerance — What's the Difference?
These get mixed up constantly, and the distinction matters because each one is tested differently:
- Food allergy — an immediate, sometimes dangerous immune reaction (hives, swelling, trouble breathing). This is what an allergist tests for. It's serious but relatively rare.
- Food sensitivity — a delayed immune reaction, usually involving IgG antibodies. Symptoms show up hours or even days later, which is why the trigger food is so hard to identify on your own. This is what we test for.
- Food intolerance — a digestive issue, not an immune one. Lactose intolerance is the classic example: your body lacks the enzyme to break something down. Uncomfortable, but a different mechanism.
Most people struggling with mystery symptoms are dealing with sensitivities — and because reactions are delayed, food journals and elimination diets often fail to catch them.
Symptoms Food Sensitivities Can Cause
Because sensitivity reactions are delayed and systemic, they don't always look like "food problems":
- Bloating, gas, or digestive discomfort after meals
- Fatigue or an energy crash after eating
- Brain fog or difficulty concentrating
- Headaches or migraines
- Joint pain or stiffness
- Skin issues — acne, eczema, rashes, rosacea
- Sinus congestion or post-nasal drip
- Stubborn weight that won't budge
- Mood dips or irritability
- Dark circles under the eyes
If you've noticed you feel better on vacation or worse after certain meals — but can't pin down the pattern — testing can connect the dots.
How Food Sensitivity Testing Works
The test measures your immune system's reaction (IgG antibodies) to a wide panel of foods — commonly 90 to 200+ items, depending on the panel. A simple blood draw or finger-prick sample is all it takes.
What makes this better than an elimination diet:
- It catches delayed reactions you'd never link to a specific food on your own
- It tests dozens of foods at once, including ones you'd never suspect
- It shows reaction severity, so you know which foods to remove completely and which just to reduce
- It saves months of restrictive trial-and-error eating
One important note: food sensitivities can change. They're often a sign of gut irritation rather than a permanent condition — which is why we frequently pair sensitivity testing with gut health testing to address the root cause, not just the symptoms.
How Testing Works at Vital Fit
Step 1 — Book your 30-minute assessment. Tell us about your symptoms, what you've already cut out, and how food affects your day-to-day life.
Step 2 — Get tested. A quick blood sample — done at a local lab in the Las Vegas area or via an at-home kit, depending on the panel.
Step 3 — Review your results together. We go through your reactive foods one by one, in plain language, and explain what the severity levels mean for your daily eating.
Step 4 — Get your personalized food plan. This isn't a list of "never eat this again." It's a practical rotation and elimination strategy: what to remove now, what to limit, what to reintroduce later, and how to heal the gut so fewer foods bother you over time.
Step 5 — Retest and reintroduce. After a gut-healing period (typically 2–3 months), many clients can bring foods back. We retest to confirm and expand your diet again — the goal is more freedom, not more restriction.
Stop Guessing. Start Knowing.
The average person with unidentified food sensitivities spends months or years cycling through elimination diets, cutting out entire food groups, and still feeling unsure. One test replaces all of that with a clear, personalized map of what your body actually wants.
