Gut & Digestive Health
Food Sensitivities
Food sensitivities are delayed reactions to certain foods that your body has a harder time handling. They are not the same as true food allergies, which tend to cause immediate symptoms like hives or swelling.
Common Symptoms
- Bloating, gas, or stomach discomfort after eating
- Diarrhea or loose stools
- Abdominal cramping
- Nausea
- Fatigue or low energy
- Brain fog or trouble concentrating
- Headaches
- Joint pain
Likely Root Causes and Contributors
- Digestive enzyme deficiencies: Some people lack the enzymes needed to properly break down certain foods. A common example is low lactase levels, which can lead to dairy intolerance and digestive symptoms.
- Gut microbiome imbalance: An unhealthy balance of gut bacteria can interfere with normal digestion and increase irritation in the digestive tract, making the body more reactive to certain foods.
- Increased intestinal permeability (leaky gut): When the gut lining becomes more permeable, partially digested food particles can pass into the bloodstream and trigger immune reactions and inflammation.
- Sensitivity to food additives and natural food chemicals: Certain people react to compounds such as MSG, sulfites, artificial preservatives, amines, or salicylates found in processed foods and some natural foods.
- Chronic inflammation and immune activation: Ongoing inflammation in the digestive system can heighten immune responses to specific foods, leading to recurring symptoms after eating them.
Patient Pain Points We Often Hear
“Most mornings I wake up bloated, puffy around the eyes, and congested, even when I am careful with my food.”
“I can feel okay while I am eating, then a few hours later I crash with fatigue, brain fog, or headaches and have no idea which food did it.”
“Social events and eating out make me anxious, because I never know if I will end up with a flare of sinus issues, skin breakouts, or body pain the next day.”
Our Approach to Healing
How We Map, Treat, and Sustain Real Recovery from Food Sensitivities with the LAM Method™
At Lam Clinic, we know food sensitivities are rarely just about one “problem food.” Most people come to us after months or years of bloating, fatigue, brain fog, sinus congestion, skin flares, or body aches that seem to come and go without a clear pattern. Our approach to healing uses the three phases of LAM Method™: Learn the Why, Address the Root, Maximize Longevity. Here’s how we use the LAM Method™ to address Food Sensitivities:
Phase 1 of LAM Method™
Learn the Why of Food Sensitivities
We focus first on understanding why your body became reactive to foods in the first place. Food sensitivities are usually a sign of deeper imbalance, not just a single “bad” food.
Testing We May Use:
- Elimination and Reintroduction Process
Still the most accurate way to identify true food sensitivities. You remove suspected foods for a few weeks, then reintroduce them one at a time while tracking symptoms. We guide you through the process so it feels clear and doable. - Food sensitivity panels (IgG)
- Comprehensive stool test (inflammation, dysbiosis, beta-glucuronidase)
- Zonulin (intestinal permeability marker)
- Mycotoxin/chemical sensitivity testing (if overlapping sensitivities)
Serum Labs may include:
- CBC, CMP
- CRP, ESR (inflammatory markers)
- Food and environmental IgE allergy testing
- Total IgA, tTG-IgA (if celiac suspected)
- Serum tryptase, histamine (if MCAS suspected)
- Vitamin D, zinc, magnesium, B12, folate

Phase 2 of LAM Method™
Address the Root of Food Sensitivities
When the body is sensitive, aggressive protocols can worsen reactions. We take a step-by-step approach.
Targeted Supplement Support
Supplements are introduced slowly and adjusted based on tolerance.
Depending on your pattern, support may focus on:
- Quercetin + Bromelain: Help stabilize mast cells and reduce inflammatory reactions, supporting the body’s response to food sensitivities.
- Probiotics: Restore gut microbiome balance, which plays a key role in reducing food sensitivities and improving tolerance.
- DAO or histamine support nutrients for patients with congestion, flushing, or delayed “allergy-like” symptoms
- Low Dose Allergen Immunotherapy (LDA): Gradually retrains the immune system to become less reactive to specific food triggers.
- IV Nutrient Therapy: Provides targeted nutrients to reduce inflammation and support immune balance involved in food sensitivity reactions.
This information is educational, not a prescription. Your actual plan is always individualized, adjusted slowly, and refined based on how your body responds.
Phase 3 of LAM Method™
Maximize Longevity
Lifestyle Foundations
- Short-term elimination and structured reintroduction: Temporarily remove common trigger foods, then reintroduce them one at a time to identify which foods are causing symptoms.
- Simple food and symptom tracking: Use a food journal or tracking app to record meals and symptoms.
- Support digestive capacity at meals: Eat slowly, chew food thoroughly, and avoid large mixed meals that combine many potential triggers.
- Reduce processed foods and additives: Limit packaged foods that contain preservatives, artificial sweeteners, MSG, or sulfites, which are common triggers for food sensitivities.
- Support gut health with fiber and fermented foods: Gradually include fiber-rich vegetables and fermented foods such as yogurt, kefir, or sauerkraut to help support a balanced gut microbiome
- A simplified maintenance plan you can follow long term and Periodic check-ins to adjust support during stress, illness, or life changes
NEM Response Circuits
How Your Body Regulate Stress
Your body handles stress through six interconnected circuits. When even one is out of balance, symptoms can show up in your heart, hormones, energy, and more.

Take the QuizFrequently Asked Questions
Can Lam Clinic help with food sensitivities?
Yes. Food sensitivities often happen when chronic stress overwhelms your NEM Stress Response, weakening gut barrier and immune balance, and slowing detox and energy systems. We look for your root triggers and overloaded circuits, then build a personalized, step-by-step plan to restore function, calm reactions, and support long-term resilience.
What are the most common food sensitivities?
Dairy, gluten grains, eggs, soy, corn, legumes, tree nuts, citrus fruits, and nightshade vegetables are the triggers we see most often in clinic.
Why do my symptoms show up hours or days after eating?
Food sensitivities usually involve delayed immune or histamine responses, not the immediate IgE reactions seen in classic allergies. That delay is why it is so hard to connect yesterday’s meal with today’s symptoms without a structured plan.
Can stress make food sensitivities worse?
Yes. Stress strains your adrenals, gut, and nervous system, which can make you more reactive to foods and slow your recovery after a flare.
What if I am sensitive to supplements too?
We see this often. We start low, change one thing at a time, and use gentle, well tolerated options so your body does not feel overwhelmed.
Do food sensitivities ever improve?
Many people see fewer reactions as their gut heals, detox pathways clear, and inflammation settles. It usually takes a step-by-step approach rather than a single fix.
Do you offer virtual visits and where are you located?
Yes. We offer secure telehealth visits worldwide and in person care at our clinic in Tustin, California. We proudly serve patients across Orange County including Irvine, Santa Ana, Orange, Costa Mesa, and Anaheim, as well as individuals throughout the United States and internationally who want personalized guidance for food sensitivities, gut healing, and NEM circuit support from the comfort of home.
The Lam Family has helped thousands recover from fatigue and stress for years.
Using advanced diagnostics and whole-body care, the Lam family looks beyond routine labs to uncover the real reasons behind fatigue—like adrenal stress, hormone imbalance, and nutrient depletion. Then, they create a personalized plan to help you heal fully and feel like yourself again.
The Pioneer of Root-Cause Healing & Whole Person Care
Before adrenal fatigue was widely understood, Dr. Michael Lam, M.D. led the way—developing one of the first clinical approaches to diagnose and treat it. His bestselling book, Adrenal Fatigue Syndrome, became a lifeline for patients around the world. Today, his children—Dr. Carrie Lam and Dr. Jeremy Lam—carry that legacy forward, building on his foundation with advanced diagnostics and whole-person care for lasting recovery.
