Foundations of Healing
Diet & nutrition
in Lyme recovery
There is no single agreed-upon Lyme diet. But there is strong agreement on the principles underneath all of them — and on what to avoid. This page compares the main approaches and explains what the evidence actually supports.
Nutrition cannot cure Lyme disease. But the wrong diet can actively obstruct recovery — feeding inflammation, damaging the gut, and exhausting an immune system already under pressure. And the right diet can meaningfully support every other treatment you are doing. It deserves more attention than it typically gets in Lyme protocols.
Why diet matters in chronic infection
Chronic Lyme disease is, at its core, a condition of sustained inflammation. Borrelia and its co-infections trigger an ongoing immune response that affects the joints, nervous system, cardiovascular system, and gut. That inflammatory state is directly influenced by what you eat — either amplified or modulated, depending on your dietary choices.
Between 70 and 80 percent of the immune system resides in the gut. The gut microbiome — the community of trillions of microorganisms living in the digestive tract — regulates immune function, produces anti-inflammatory compounds, and communicates directly with the brain via the gut-brain axis. When that microbiome is disrupted — by infection, by antibiotic treatment, or by a poor diet — the downstream effects reach every system in the body.
For Lyme patients, this is particularly significant. Prolonged antibiotic use, which many patients undergo, can substantially alter gut flora — reducing microbial diversity and allowing harmful organisms like Candida to overgrow. Diet is the primary tool for rebuilding what treatment disrupts.
Some researchers, including Dr. Sabine Hazan, have proposed that in some cases of chronic Lyme, the persistent illness may be partly attributable to severe disruption of the intestinal microbiome — rather than to ongoing active infection alone. If this is correct, restoring gut health becomes not a supporting strategy but a central one.
What all approaches agree on
Before comparing individual diets, it is worth noting what they all share. Every reputable dietary framework for chronic illness — whether Mediterranean, ketogenic, AIP, or Paleo — agrees on the following:
- Refined sugar and high-fructose corn syrup
- Processed and ultra-processed foods
- Industrial seed oils (canola, soy, corn, cottonseed)
- Refined carbohydrates and white flour products
- Alcohol
- Artificial additives, colours, and preservatives
- Vegetables — especially leafy greens and cruciferous
- Wild-caught fatty fish (salmon, sardines, mackerel)
- Olive oil and other healthy fats
- Herbs and spices with anti-inflammatory properties
- Fermented foods for microbiome support
- Adequate clean protein for tissue repair
Refined sugar is the single most important thing to eliminate. It suppresses white blood cell activity, feeds Candida overgrowth, and drives the inflammatory gut bacteria associated with dysbiosis. For a Lyme patient whose immune system is already compromised, sugar is a direct obstacle to recovery.
The main dietary approaches — compared
These are the diets most frequently recommended by Lyme-literate practitioners, nutritionists, and patient communities. Each has a different focus, different restrictions, and different practical demands.
The Mediterranean diet is the most extensively studied dietary pattern in the world, with the strongest evidence base for reducing systemic inflammation, supporting immune function, and improving gut microbiome diversity. It is the closest thing to a scientific consensus on anti-inflammatory eating.
It emphasises whole, minimally processed foods — vegetables, fruits, legumes, whole grains, nuts, olive oil, and fish — with moderate amounts of dairy and poultry, and limited red meat. Its anti-inflammatory effects are well-documented across cardiovascular, autoimmune, and metabolic conditions. For Lyme patients specifically, the Mediterranean diet's effect on the gut microbiome is particularly relevant: it consistently promotes the growth of beneficial bacteria (Lactobacillus, Bifidobacterium, Faecalibacterium prausnitzii) that produce short-chain fatty acids — compounds that reduce intestinal permeability and calm systemic inflammation.
- Olive oil as primary fat
- Fatty fish 2–3× per week
- Abundant vegetables
- Legumes and whole grains
- Nuts and seeds
- Herbs: turmeric, garlic, ginger
- Berries and antioxidant-rich fruits
- Red meat (occasional only)
- Refined sugar
- Processed foods
- Industrial seed oils
- Alcohol (wine in strict moderation)
The most sustainable long-term approach and the best-evidenced for systemic inflammation. Accessible, varied, and practical for most people. A strong default choice for Lyme patients who are not dealing with significant gut damage or specific food sensitivities.
The AIP diet was developed specifically for autoimmune conditions, and is widely used in the Lyme community because chronic Lyme frequently involves autoimmune-like mechanisms — including leaky gut, immune dysregulation, and chronic inflammation driven partly by food sensitivities.
It is a strict elimination diet that removes all foods theorised to increase gut permeability or trigger immune responses: grains, legumes, dairy, eggs, nightshade vegetables, nuts, seeds, alcohol, and certain oils. After 6–8 weeks, foods are systematically reintroduced one at a time to identify individual triggers. The rationale is that by removing all possible inflammatory triggers simultaneously, the gut lining can heal and the immune system can reset before individual sensitivities are identified.
- Meat and organ meats
- Wild fish and seafood
- Non-nightshade vegetables
- Fermented vegetables
- Bone broth
- Coconut products
- Olive oil and avocado oil
- Fruits (moderate)
- All grains (including rice and oats)
- All legumes
- All dairy
- Eggs
- Nightshades (tomatoes, peppers, etc.)
- Nuts and seeds
- All processed foods
- Alcohol
The most demanding dietary approach — significant planning required. Most useful for patients with pronounced gut symptoms, suspected leaky gut, known food sensitivities, or autoimmune complications from Lyme. The elimination phase is temporary; the goal is eventually a wider, personalised diet based on what your body tolerates.
The ketogenic diet — very low carbohydrate, high fat — shifts the body into a metabolic state called ketosis, in which ketone bodies become the primary fuel source instead of glucose. For Lyme patients, the most compelling argument for ketogenic eating is its documented effect on neuroinflammation.
Borrelia infection produces profound inflammation in the brain, contributing to brain fog, cognitive impairment, fatigue, and mood disturbances. Ketones — particularly beta-hydroxybutyrate — are anti-inflammatory: they inhibit the NLRP3 inflammasome, a key driver of neuroinflammation, and activate anti-inflammatory pathways including AMPK and Nrf-2. Several Lyme-literate practitioners report significant improvement in neurological symptoms in patients who adopt ketogenic eating. Tim Ferriss, who documented his own Lyme recovery publicly, specifically credited a ketogenic protocol as a significant factor.
The most recommended variant in the Lyme community is the ketotarian approach — a plant-heavy ketogenic diet that prioritises non-starchy vegetables, avocado, olive oil, nuts, and fatty fish over the conventional meat-and-dairy-heavy keto diet. This avoids the gut microbiome damage associated with high animal fat intake on standard keto.
- Non-starchy vegetables (freely)
- Avocado and olive oil
- Fatty fish
- Nuts and seeds
- Eggs (if tolerated)
- Coconut products
- Small amounts of quality protein
- All grains and starchy vegetables
- Fruit (except small amounts of berries)
- Sugar in all forms
- Legumes
- Processed foods
- Alcohol
Most valuable for patients with significant neurological symptoms — brain fog, fatigue, cognitive impairment. No published clinical trials in Lyme patients specifically, but mechanistically well-supported and widely reported to help in the patient community. Standard (meat-heavy) keto may harm gut diversity over time — the plant-based variant is strongly preferred.
The Paleo diet removes processed foods and modern agricultural products — grains, legumes, dairy, refined sugar — in favour of foods presumed to match human evolutionary eating patterns: meat, fish, vegetables, fruits, nuts, and seeds. For Lyme patients, the relevant benefit is the removal of foods most associated with intestinal inflammation and food sensitivities.
The Autoimmune Paleo variant (which overlaps significantly with AIP) adds further restrictions — removing eggs and nightshades — and is specifically used for patients where autoimmunity is a concern. Paleo is less restrictive than AIP and more practical for most people to sustain, making it a reasonable middle ground for Lyme patients who want a whole-foods approach without the full rigour of elimination dieting.
- Quality meat and fish
- Eggs (if tolerated)
- Vegetables and fruits
- Nuts and seeds
- Healthy fats (olive oil, coconut oil)
- Herbs and spices
- All grains
- All legumes
- Dairy
- Refined sugar
- Processed foods
- Industrial seed oils
A solid anti-inflammatory foundation. Less researched than Mediterranean but well-regarded in integrative medicine. Best suited for patients with suspected grain or legume sensitivities. Easier to sustain than AIP for most people.
This is not a named diet so much as a shared framework endorsed by most Lyme-literate practitioners as a minimum baseline. It simply means: eat real food, mostly plants, nothing processed, and keep blood sugar stable. Phillips and Parish, in their book Chronic, describe this as "a whole-foods, low-glycaemic approach" — practical for most patients regardless of whether they adopt one of the stricter protocols above.
Low-glycaemic eating specifically matters because blood sugar spikes drive inflammation and feed pathogenic gut bacteria. Keeping glucose stable through fibre-rich, low-sugar, protein-adequate eating reduces the inflammatory load and supports immune regulation.
The minimum starting point for any Lyme patient. If committing to AIP or keto feels overwhelming at first, this approach — remove processed food, remove sugar, eat real food — is where to begin. It is also the most sustainable long-term framework for most people.

The gut — your most important recovery organ
Whatever dietary approach you choose, gut health deserves specific attention — especially if you have been on antibiotics. Antibiotics save lives and are essential in Lyme treatment, but they do not discriminate: they kill beneficial bacteria alongside pathogenic ones. The result is often significant dysbiosis that persists long after antibiotic treatment ends.
Take probiotics throughout antibiotic treatment and for several weeks after. At least 60 billion CFU per day is typically recommended. Take them at least 2 hours away from antibiotics so they are not destroyed before they can colonise. Saccharomyces boulardii is particularly useful alongside antibiotics — it is a yeast-based probiotic that survives antibiotic exposure and specifically inhibits Candida overgrowth and C. difficile.
Probiotics need fuel. Prebiotics — the fibre found in vegetables, onions, garlic, leeks, artichokes, and asparagus — feed beneficial gut bacteria and encourage their growth. Without adequate fibre, probiotic supplementation has limited long-term effect. This is one reason why plant-heavy dietary approaches outperform low-plant versions for gut health.
Bone broth is rich in collagen, glutamine, and glycine — amino acids that support the repair of the intestinal lining. Regular consumption of bone broth is a common recommendation in both AIP and integrative Lyme protocols for addressing leaky gut. Homemade versions (slow-cooked from quality animal bones) provide the most benefit.
Fermented vegetables (sauerkraut, kimchi), kefir, and natural yoghurt introduce live beneficial bacteria from food. Unlike commercial probiotics, fermented foods contain diverse microbial species and supporting compounds. They are one of the best tools for rebuilding gut diversity after antibiotic damage — if tolerated.
Antibiotic use frequently leads to Candida (yeast) overgrowth in the gut — manifesting as bloating, sugar cravings, brain fog, and fatigue that mirror Lyme symptoms. Removing all sugar and refined carbohydrates is the dietary foundation of addressing Candida. Saccharomyces boulardii, caprylic acid, and oregano oil are commonly used alongside dietary change.
Key nutrients for Lyme recovery
Beyond overall dietary pattern, several specific nutrients are particularly relevant in chronic Lyme:
Found in fatty cold-water fish (salmon, mackerel, sardines, anchovies, herring — the "SMASH" fish), omega-3s produce specialised pro-resolving mediators that blunt IL-17, a pro-inflammatory cytokine chronically elevated in Lyme infection. Several servings of fatty fish per week is a consistent recommendation. Fish oil supplementation is an alternative for those who do not eat fish regularly.
Essential for immune modulation. Chronic Lyme patients frequently test deficient. Vitamin D helps regulate the immune response, potentially reducing the autoimmune component of chronic Lyme. Fatty fish, eggs, and fortified dairy contribute dietary vitamin D, but supplementation is often necessary to correct deficiency — optimal levels typically require testing and targeted dosing.
Chronic infection generates significant oxidative stress. Antioxidants help neutralise free radicals, repair cellular damage, and support immune function. Vitamin C also plays a role in collagen production — important for joint health in Lyme patients. Found in citrus, bell peppers, berries (C) and nuts, seeds, leafy greens (E).
Glutathione is the body's master antioxidant. Cruciferous vegetables (broccoli, cauliflower, cabbage, Brussels sprouts) contain glucosinolates that stimulate glutathione production. This supports detoxification — critical during treatment as dying bacteria release toxins (Herxheimer reactions). N-acetyl cysteine (NAC) is a common supplement used to directly boost glutathione.
Involved in over 300 enzymatic reactions and essential for nerve and muscle function. Often depleted in chronic illness. Dark leafy greens, nuts, seeds, and dark chocolate are dietary sources. Magnesium supplementation (glycinate or malate form) is commonly used in Lyme protocols for muscle pain, sleep, and nervous system support.
Which approach is right for you?
There is no single answer. The right diet depends on your current symptoms, your gut status, your practical capacity, and what you can sustain. Here is a framework for thinking about it:
If you have significant neurological symptoms — brain fog, cognitive impairment, fatigue — consider a ketogenic or ketotarian approach. The anti-inflammatory effect of ketones on the brain is the most specific dietary intervention for this symptom cluster.
If you have gut symptoms, suspected leaky gut, or have been on long-term antibiotics — AIP or a Mediterranean diet with strong probiotic and fermented food focus. The AIP elimination phase can identify specific trigger foods that would otherwise remain hidden.
If you want a sustainable long-term framework — Mediterranean is the most evidence-supported, the most varied, and the easiest to maintain. It covers the anti-inflammatory and gut-support bases without the restrictiveness of AIP or the metabolic demands of keto.
If you are overwhelmed and do not know where to start — begin with one step: remove all refined sugar and processed food. That single change, done consistently, does more than any specific diet done imperfectly.
Many Lyme patients cycle between approaches — using AIP to identify sensitivities and repair the gut, then transitioning to a Mediterranean or whole-foods framework for long-term maintenance, while incorporating ketogenic elements during periods of active neurological flare. Working with a nutritionist who understands chronic illness is worth considering if dietary change feels difficult to navigate alone.
