Therapeutic Diet Food Lists: AIP, Low Histamine, Low Oxalate, GERD & More — A Complete Guide

Most diet food lists you find online are copy-paste jobs from unreliable sources. I’ve seen the same incorrect AIP food lists circulate across dozens of websites, and many “low histamine” guides contradict each other entirely. As someone who has reviewed the actual clinical literature behind these diets, I’m giving you evidence-based food lists that reflect what the research actually supports — not what bloggers keep copying from each other.

This guide covers five therapeutic diets that serve specific medical purposes: AIP (Autoimmune Protocol), Low Histamine, Low Oxalate, GERD, and Herpes Diet. Each has a distinct scientific rationale, and each requires a different approach.

AIP Diet Food List: The Autoimmune Protocol

The AIP diet is the most restrictive therapeutic elimination diet, designed specifically for people with autoimmune conditions like Hashimoto’s thyroiditis, rheumatoid arthritis, and inflammatory bowel disease. Here’s what most guides get wrong: AIP isn’t meant to be followed forever. It’s a temporary elimination phase (typically 30-90 days) followed by systematic food reintroduction to identify your personal triggers.

AIP Foods to Eat

Vegetables (except nightshades): broccoli, spinach, kale, carrots, cauliflower, sweet potatoes, zucchini, squash, cabbage, beets, asparagus, Brussels sprouts, greens
Fruits (in moderation): berries, apples, pears, peaches, melons, bananas, plantains
Quality meats: grass-fed beef, wild-caught fish, chicken, turkey, lamb, organ meats
Healthy fats: coconut oil, olive oil, avocado, avocado oil
Fermented foods: sauerkraut (check ingredients), kimchi (AIP-compliant), coconut yogurt
Herbs and fresh aromatics: garlic, ginger, turmeric, basil, oregano, rosemary, thyme, parsley, cinnamon, sage
Natural sweeteners (limited): honey, maple syrup
Broths: bone broth, vegetable broth

AIP Foods to Avoid

All grains: wheat, rice, oats, corn, quinoa, barley, millet
All dairy: milk, cheese, yogurt, butter, ghee (some protocols allow ghee later)
Nightshade vegetables: tomatoes, potatoes (not sweet potatoes), eggplant, peppers, paprika, cayenne
Nuts and seeds: almonds, walnuts, cashews, chia, flax, sesame, sunflower seeds
Seed-based spices: cumin, coriander, fennel, mustard, nutmeg, pepper
Legumes: beans, lentils, peas, peanuts, soy
Eggs: including hidden egg ingredients
Processed foods, refined sugars, and food additives
Alcohol and coffee

My honest take: AIP is effective for many autoimmune patients, but it’s extremely challenging to follow. Don’t attempt it without guidance from a healthcare provider. Studies from 2017 and 2019 showed significant symptom improvement in IBD patients following AIP, but adherence was the biggest challenge.

Low Histamine Food List: For Histamine Intolerance and Mast Cell Activation

Histamine intolerance occurs when your body can’t break down histamine properly, often due to low DAO (diamine oxidase) enzyme activity. Here’s the challenge: histamine levels in food vary dramatically based on freshness, storage time, and preparation method. A “low histamine food list” is a starting point, not a guarantee.

Generally Low Histamine Foods

Freshly cooked meats: freshly prepared chicken, beef, lamb, turkey (avoid leftovers)
Fresh fish: only if caught and eaten same day; frozen fish is often safer than “fresh” fish at the counter
Eggs: fresh, well-cooked (some people react to egg white)
Fresh vegetables: asparagus, bell peppers, beets, broccoli, cabbage, carrots, cauliflower, cucumber, garlic, kale, lettuce, onions, pumpkin, squash, sweet potato, zucchini
Fresh fruits (limited): apples, blackberries, blueberries, cherries, coconut, kiwi, mango, melon, pears, pomegranate, rhubarb
Grains: rice, quinoa, millet, buckwheat, oats
Fats: olive oil, coconut oil, butter (if tolerated)
Herbs: basil, parsley, oregano, thyme, rosemary, sage, ginger, turmeric
Non-dairy alternatives: coconut milk, rice milk

High Histamine Foods to Avoid

Fermented foods: sauerkraut, kimchi, yogurt, kefir, kombucha, vinegar, soy sauce
Aged cheeses: parmesan, cheddar, blue cheese, brie
Processed meats: salami, pepperoni, bacon, hot dogs, deli meats
Fish and seafood (not fresh): canned fish, shellfish, smoked fish
Leftovers: histamine builds as food sits, even in the refrigerator
Alcohol: wine, beer, and spirits block DAO enzyme
Certain vegetables: tomatoes, spinach, eggplant, avocado (contain histamine or trigger release)
Certain fruits: strawberries, citrus fruits, bananas (ripe), papaya, pineapple
Chocolate and cocoa
Nuts: walnuts, cashews, peanuts

Critical tip: Always choose the freshest foods possible. Buy meat frozen or cook it the day you buy it. Don’t eat leftovers — cook fresh meals daily. This matters more than following a perfect list.

Low Oxalate Food List: For Kidney Stone Prevention

Oxalates are naturally occurring compounds found in many plant foods. For most people, they’re harmless. But if you’re prone to calcium oxalate kidney stones, reducing dietary oxalate can significantly lower your risk.

Low Oxalate Foods (Eat Freely)

Proteins: most meats, fish, poultry, eggs, dairy products
Fruits: bananas, cherries, melons, grapes, mangoes, peaches, plums, apples (peeled), pears
Vegetables: cauliflower, cabbage, cucumber, mushrooms, onions, peas, radishes, turnips, zucchini, bell peppers, lettuce, broccoli (moderate)
Grains: white rice, white bread, corn, barley, oats
Beverages: water (lots of it), apple juice, grape juice, lemonade made from real lemons (citrate helps)

High Oxalate Foods (Limit or Avoid)

Leafy greens: spinach, Swiss chard, beet greens, collard greens
Vegetables: beets, rhubarb, okra, sweet potatoes, potatoes, leeks
Nuts and seeds: almonds, cashews, peanuts, sesame seeds, tahini, nut butters
Legumes: most beans, lentils, soy products
Grains: whole wheat, bran, quinoa, buckwheat, brown rice (higher than white)
Chocolate and cocoa: very high in oxalate
Tea and coffee: especially black tea and dark roast coffee
Soy products: tofu, soy milk, edamame

Important: Don’t eliminate all oxalate — that’s nearly impossible and unnecessary. Aim for under 100mg of oxalate per day if you’re stone-prone. Also, increase calcium intake from foods (not supplements) at meals. Dietary calcium binds oxalate in the gut, preventing absorption.

GERD Diet Food List: Managing Acid Reflux

GERD (gastroesophageal reflux disease) affects about 20% of Americans. While medication helps, dietary changes are the foundation of long-term management. The GERD diet focuses on reducing foods that relax the lower esophageal sphincter (LES) or increase stomach acid production.

GERD-Friendly Foods to Eat

Lean proteins: chicken breast, turkey, fish, egg whites, tofu
Complex carbohydrates: oatmeal, brown rice, whole grain bread, couscous
Non-citrus fruits: melons, bananas, apples, pears
Vegetables: broccoli, green beans, cauliflower, leafy greens, potatoes, cucumbers
Healthy fats: olive oil, avocado (in moderation for some), nuts (in moderation)
Ginger: natural anti-inflammatory that may help with digestion
Alkaline foods: these help neutralize stomach acid

Foods to Avoid with GERD

Fried and fatty foods: relax the LES and delay stomach emptying
Citrus fruits and tomatoes: highly acidic
Chocolate: contains methylxanthine, which relaxes the LES
Caffeine: coffee, tea, energy drinks — stimulates acid production
Alcohol: relaxes LES and irritates esophageal lining
Carbonated beverages: causes bloating and pressure on the LES
Onions and garlic: triggers for many people (though healthy otherwise)
Mint and peppermint: relaxes the LES
Spicy foods: irritates the esophagus in many patients
Late-night eating: eating within 3 hours of lying down worsens symptoms

My clinical observation: GERD triggers are highly individual. The best approach is to eliminate common triggers for 2-4 weeks, then reintroduce one at a time to identify your personal triggers. Keep a food-symptom diary during this process.

Herpes Diet Food List: Foods That Help Prevent Outbreaks

While diet alone can’t cure herpes (HSV-1 or HSV-2), certain foods can help reduce outbreak frequency and severity. The strategy focuses on two goals: supporting immune function and avoiding foods high in arginine (which the herpes virus uses to replicate), while prioritizing lysine (which competes with arginine).

Foods to Prioritize (High Lysine, Low Arginine)

Fish: salmon, cod, trout, sardines
Poultry: chicken, turkey
Beef and lamb
Dairy: yogurt, cheese, milk (if tolerated)
Eggs
Most fruits: apples, pears, figs, mango, papaya
Most vegetables: broccoli, cabbage, cauliflower, beets, avocado

Foods to Limit (High Arginine)

Nuts and seeds: walnuts, almonds, cashews, peanuts, sesame seeds, pumpkin seeds
Chocolate
Whole grains: wheat, oats, brown rice
Coconut and coconut products
Protein powders: especially those containing arginine
Gelatin

Additional Immune-Supporting Strategies

Vitamin C-rich foods: bell peppers, strawberries, citrus (if not trigger), broccoli
Zinc-rich foods: oysters, beef, pumpkin seeds (despite arginine — the zinc benefit may outweigh)
Anti-inflammatory foods: fatty fish, turmeric, ginger, leafy greens
Avoid excessive alcohol and sugar — both suppress immune function

Evidence check: Research on lysine supplementation shows mixed but generally positive results for reducing outbreak frequency. A 2017 review found that lysine supplementation (typically 1,000-3,000mg daily) may help prevent recurrences, though more rigorous trials are needed. Dietary lysine alone may not provide therapeutic doses, but it’s a supportive strategy.

Gastroenteritis Food to Avoid: When You Have a Stomach Bug

While not a long-term therapeutic diet, knowing what to avoid during acute gastroenteritis (stomach flu) can significantly affect your recovery time.

Foods to Absolutely Avoid

Dairy products: temporary lactose intolerance is common after stomach bugs
Fatty, greasy, or fried foods: hard to digest, worsens diarrhea
High-fiber foods: raw vegetables, whole grains, legumes — increase bowel movements
Spicy foods: irritates inflamed digestive tract
Alcohol and caffeine: dehydrating and irritating
Sugary foods and drinks: can worsen diarrhea (especially fruit juices)
Artificial sweeteners: sorbitol and mannitol can cause osmotic diarrhea

What to Eat Instead

BRAT diet foods: bananas, rice, applesauce, toast
Clear broths for hydration and electrolytes
Plain crackers
Boiled potatoes (without butter or skin)
Steamed chicken (plain, no skin)
Electrolyte solutions

As symptoms improve (usually after 24-48 hours), gradually reintroduce normal foods. Start with low-fat, bland options and add variety slowly.

Frequently Asked Questions

Can I follow multiple therapeutic diets at once?

I don’t recommend it without professional guidance. Combining AIP with low histamine, for example, leaves you with an extremely limited diet that risks nutrient deficiencies. Work with a dietitian or functional medicine practitioner to prioritize which diet addresses your most pressing symptoms first.

How long should I follow an elimination diet?

Most elimination diets are meant to be temporary. AIP typically runs 30-90 days before reintroduction. Low histamine diets are followed until symptoms stabilize, then foods are reintroduced systematically. Low oxalate diets are generally long-term for recurrent stone formers. Work with a healthcare provider to determine the right timeline for your situation.

Are these diets scientifically proven?

The evidence varies by diet. AIP has small but promising studies for IBD and Hashimoto’s. Low oxalate diets are well-established for calcium oxalate kidney stones. GERD dietary modifications are supported by extensive clinical experience, though individual triggers vary. Low histamine diets have less formal research but strong anecdotal and clinical support. Herpes dietary strategies have the weakest direct evidence, though the lysine-arginine ratio is biologically plausible.

Can I get enough nutrients on these restrictive diets?

This is a valid concern. The more restrictive the diet, the higher the risk of nutrient gaps. AIP eliminates major food groups and requires careful planning to ensure adequate calcium, vitamin D, fiber, and B vitamins. Consider working with a registered dietitian and using targeted supplementation where appropriate.

Bottom Line

Therapeutic diets are tools, not permanent lifestyles. The AIP diet, low histamine protocol, low oxalate diet, GERD diet, and herpes diet each serve specific purposes backed by varying levels of evidence. The key to success with any of them is:

Follow the elimination phase strictly for the recommended period
Reintroduce foods systematically to identify your personal triggers
Work with a healthcare professional to prevent nutrient deficiencies
Personalize the diet based on your body’s responses, not just a generic list

Food lists are starting points. Your body’s reactions are the ultimate guide.
