When I first began working with elimination diets, I assumed healing was a straight line: remove the offending foods, wait, and feel better. Seven years later, after hundreds of food diaries and countless conversations with readers, I’ve learned that real, lasting digestive comfort rarely follows a single path. Instead, it rests on three interconnected foundations that I call the pillars of healing. These aren’t abstract ideals—they’re practical, daily actions that support the body’s natural ability to repair and regulate itself.
Below, I break down each pillar with concrete steps you can apply to your own paleo or autoimmune protocol (AIP) journey. None of this replaces medical advice, but it may give you a framework to discuss with your practitioner.
Pillar 1: Removing the Irritants Without Starving the Microbiome
The first pillar is about subtraction—but not reckless subtraction. A common mistake is to strip the diet down to a few “safe” foods and stay there indefinitely. That approach can lead to nutrient gaps and a dwindling microbial diversity, which paradoxically makes digestion more brittle over time.
Instead, think of removal as a precise, temporary step. The goal is to identify which foods consistently trigger symptoms—bloating, gas, brain fog, skin issues—and eliminate only those for a defined period (typically 30–60 days). This is where a detailed food and symptom diary becomes indispensable. Without data, you’re guessing.
During the elimination phase, prioritize nutrient-dense foods that are unlikely to cause reactions: well-cooked vegetables, high-quality animal proteins, healthy fats, and fermented foods (if tolerated). The goal isn’t to eat as few foods as possible, but to eat a wide variety of low-inflammatory options. For example, instead of eating only chicken and broccoli, rotate in lamb, sardines, squash, leafy greens, and bone broth.
One nuance that often surprises people: individual genetics can influence how well you tolerate certain foods even within a paleo template. For instance, variations in MTHFR and related methylation pathways can affect how your body processes folate-rich vegetables or handles histamine. A deeper look at this interplay is something I explored in a post about MTHFR and Paleo: What Standardized Treatment Regimes Miss About Digestion. Understanding your own biochemistry can help you refine the elimination list rather than following a one-size-fits-all protocol.
After the elimination period, the second phase begins: systematic reintroduction. Add one new food every three to four days, noting any changes in symptoms. This step is often rushed, but it’s where the real learning happens. You discover not just what you react to, but how much you can tolerate and under what conditions (e.g., cooked vs. raw, alone vs. with fat).
Pillar 2: Supporting the Digestive Process from Mouth to Colon
The second pillar shifts focus from what you eat to how you eat and how your digestive system processes that food. Even the most pristine paleo plate can cause discomfort if the digestive chain is weak at any link.
Start with the mouth. Chewing thoroughly—until food is almost liquid—is the single most underrated digestive aid. It breaks down fiber, mixes in salivary enzymes, and signals the stomach to prepare acid and enzymes. Many of us eat too quickly, swallowing large chunks that burden the stomach and small intestine.
Next, consider stomach acid and enzyme support. Low stomach acid is surprisingly common, especially in people who have used proton pump inhibitors or followed long-term low-carb diets. Signs include feeling full after a few bites, burping, or undigested food in stool. Simple strategies like drinking lemon water or apple cider vinegar before meals (if tolerated) can help, but the key is to work with a practitioner to rule out underlying issues like H. pylori or autoimmune gastritis.
Food preparation also matters. Cooking vegetables thoroughly—steaming, roasting, or slow-cooking—breaks down cell walls and reduces compounds like lectins and oxalates that can irritate a sensitive gut. Soaking and sprouting nuts and seeds can similarly lower anti-nutrient levels. For those following AIP, organ meats are a powerhouse of nutrients, but many find them challenging to prepare. A practical guide on How to Cook Organ Meats for AIP: Simple Steps to Make Liver Taste Good can make this pillar more approachable.
Finally, support the colon by feeding your beneficial bacteria. Soluble fiber from cooked root vegetables, green plantains, and well-cooked asparagus acts as prebiotic fuel. But go slowly—too much fiber too fast can backfire. And don’t forget the role of fermented foods: sauerkraut, kimchi, and coconut yogurt introduce live microbes that bolster the gut ecosystem. Start with a teaspoon per day and increase gradually.
Pillar 3: Calming the Nervous System to Allow Digestion
The third pillar is the one most often neglected in paleo circles, yet it may be the most powerful. Digestion is governed by the parasympathetic nervous system—the “rest and digest” branch. When you’re stressed, anxious, or constantly in “fight or flight,” blood flow diverts away from the gut, enzyme secretion drops, and intestinal permeability increases. You can eat the perfect diet and still feel bloated if your nervous system is stuck in high gear.
This isn’t about vague “stress reduction.” It’s about concrete practices that shift the autonomic balance. Eating in a calm environment, without screens or rushing, is a foundational step. Put your fork down between bites, breathe slowly, and stay seated for at least 10 minutes after the meal.
Sleep is another non-negotiable. Poor sleep disrupts the gut barrier and alters the microbiome composition. Aim for seven to nine hours of quality sleep, and consider a consistent bedtime routine that includes dim lighting and no electronics an hour before bed.
Mindfulness or gentle movement—like walking after meals, yoga, or diaphragmatic breathing—also supports vagal tone, which is the nerve highway between the brain and gut. Even five minutes of slow, deep breathing before a meal can make a noticeable difference in how well you digest. For a deeper exploration of the brain-gut connection, the post Why Your Brain Might Be Sabotaging Your Paleo Diet unpacks the science behind this pillar.
One more practical tip: if you feel bloated after eating, try lying on your left side for 10–15 minutes. This position uses gravity to help gas move through the colon and can provide rapid relief without any supplements.
Bringing the Three Pillars Together
These three pillars don’t operate in isolation. Removing triggers (pillar one) is less effective if you’re not digesting properly (pillar two), and both are undermined by chronic stress (pillar three). A realistic approach is to work on one pillar at a time, but keep the others in mind.
For example, if you’re starting an elimination diet, first focus on pillar one: identify your trigger foods and build a nutrient-dense baseline. Once that feels stable, move to pillar two: improve your chewing habits, experiment with food preparation, and introduce fermented foods slowly. When you hit a plateau or experience setbacks, turn to pillar three: evaluate your sleep, stress levels, and eating environment.
Healing is rarely linear, but a framework like this gives you a map when you feel lost. The next time you’re bloated after a meal that “should” have been fine, ask yourself: Did I eat too quickly? Was I stressed? Did I reintroduce something too soon? The answer often lies in the interplay of these three pillars, not in a single magic food or supplement.
Start with one small change today—maybe chewing each bite 20 times or adding a five-minute walk after dinner—and track what happens. Over weeks, these small adjustments compound into a digestive system that works with you, not against you.
