Your Phase 1 LEAP Shopping List: A Complete Grocery Guide for the Elimination Diet

Phase 1 of the LEAP ImmunoCalm protocol is the most restrictive — and the most important. Your Certified LEAP Therapist (CLT) will select 20-25 foods from your Green (lowest-reactive) MRT results. For the first 5-10 days, these foods are your entire diet.

This guide covers how to build a practical, sustainable grocery list from your Phase 1 foods — organized by category, with shopping strategies that make the elimination phase manageable instead of miserable.

Before You Shop: Phase 1 Fundamentals

Phase 1 of the LEAP diet uses only your Green (lowest-reactive) MRT results. Here’s what that means for grocery shopping:

• Single-ingredient foods only. During Phase 1, every item you buy should have exactly one ingredient — the food itself. Plain chicken, fresh broccoli, white rice. Not “seasoned chicken” or “rice pilaf mix.”
• No packaged foods with ingredient lists. If a product has more than one ingredient, skip it during Phase 1. The exception: your CLT may approve specific packaged items after verifying every ingredient.
• Your list is personalized. Chicken might be Green for you and Red for someone else. That’s why generic “elimination diet shopping lists” don’t work — they’re not based on your blood test.
• Stock up for the full 5-10 days. Running out of approved food is the #1 reason clients cheat during Phase 1. Buy enough to cover every meal.

Proteins

The MRT 176 panel tests the following protein sources. If any of these are on your Green list, buy them in their plainest form:

What to avoid: Pre-marinated meats, deli meats (contain nitrates, MSG, and “natural flavors”), breaded or seasoned fish, protein powders, and any meat injected with “broth” or “solution.”

Vegetables

Vegetables are the foundation of Phase 1 meals. The MRT panel tests many common vegetables. Buy fresh or plain frozen (no sauce, no seasoning):

Fresh vs. Frozen: Both are fine for Phase 1 as long as the frozen version has a single ingredient. Avoid frozen vegetables with butter sauce, cheese sauce, or “seasoning blend.” Read the back of the bag — if it lists anything besides the vegetable, put it back.

Fruits

Fruits add natural sweetness and variety to Phase 1. The MRT panel tests many common fruits. Buy fresh or plain frozen:

• Berries: Blueberries, strawberries, raspberries, blackberries (fresh or frozen, single ingredient)
• Citrus: Oranges, grapefruit, lemons, limes
• Tree fruits: Apples, pears, peaches, plums
• Tropical: Bananas, mango, pineapple
• Melon: Watermelon, cantaloupe, honeydew
• Grapes: Red or green

What to avoid: Dried fruits (often contain sulfites, a tested MRT chemical), fruit cups in syrup (citric acid, ascorbic acid), fruit juices with “natural flavors,” and pre-cut fruit platters (may have preservative sprays).

Grains & Starches

Grains provide the caloric foundation of Phase 1. Without adequate starch, clients under-eat and feel fatigued. If any of these are on your Green list, stock up:

• White rice — The safest grain for most LEAP clients. Buy plain long-grain or jasmine. Avoid “enriched” rice with added vitamins (may contain soy-based coatings).
• Oats (if Green) — Buy plain rolled oats or steel-cut oats. Avoid instant oatmeal packets (contain “natural flavors,” maltodextrin, and other additives).
• Quinoa (if Green) — Rinse thoroughly before cooking. Buy plain, not flavored.
• Sweet potatoes & white potatoes — Double as starch and vegetable. Versatile for every meal.
• Rice cakes — Plain, unflavored. Check the label — some brands add “natural flavors” or caramel color even to “plain” rice cakes.

Fats & Oils

You need cooking fats. Phase 1 requires adequate calories, and fat makes food taste good — which matters when your options are limited:

• Olive oil — Extra virgin, single ingredient. Check the label. Some brands add canola or soy oil.
• Avocado oil — Good for high-heat cooking. Must be 100% avocado oil (adulteration is common).
• Coconut oil (if Green) — Unrefined, single ingredient.
• Butter (if cow’s milk is Green) — Unsalted, plain. No “butter blends” or “spreadable butter” (those contain canola oil).
• Avocados — Whole avocados are a whole food fat source. Pre-made guacamole is not Phase 1 safe (contains citric acid, garlic, onion, etc.).

Seasonings & Herbs

Flavor is critical for Phase 1 compliance. Bland food leads to cheating. The MRT panel tests several common seasonings:

• Sea salt — Always safe. Buy plain sea salt, not “seasoned salt” or “garlic salt.”
• Black pepper (if Green) — Buy whole peppercorns or plain ground pepper. Avoid pepper blends.
• Individual dried herbs (if Green) — Basil, oregano, thyme, rosemary, parsley, dill. Buy single-herb containers, not “Italian seasoning” blends (which may contain unlisted fillers).
• Garlic (if Green) — Fresh cloves only. Garlic powder may contain anti-caking agents.
• Turmeric (if Green) — Fresh root or plain ground turmeric.
• Ginger (if Green) — Fresh root. Avoid powdered ginger that lists “silicon dioxide” (anti-caking agent).

What to avoid: All seasoning blends (“taco seasoning,” “lemon pepper,” “steak rub”), soy sauce, Worcestershire sauce, hot sauce, ketchup, mustard, and any condiment with an ingredient list longer than one item.

Beverages

Hydration is essential during Phase 1. Your body is processing inflammatory changes, and adequate water supports the detox process:

• Water — Always safe. Aim for half your body weight in ounces daily. Filtered or spring water is fine.
• Herbal tea — Only if the specific herb is on your Green list. Buy single-ingredient teas (pure chamomile, pure peppermint). Avoid tea blends and anything listing “natural flavors.”
• Coffee — Only if coffee is on your Green list. Black only — no creamer, no sugar, no flavored coffee beans.

What to avoid during Phase 1: All alcohol, soda, sports drinks, electrolyte packets (contain citric acid, “natural flavors,” sucralose), flavored water, juice, smoothie mixes, and protein shakes.

Phase 1 Shopping Strategy

Follow this approach to make your Phase 1 grocery runs efficient and complete:

Navigating Packaged Foods During Phase 1

The general rule is simple: avoid packaged foods during Phase 1. But when you must buy something with a label, here’s how to evaluate it:

1. Count the ingredients. If there’s more than one, proceed with caution.
2. Check every ingredient against your Green list. If any ingredient is not on your approved list, put it back.
3. Watch for hidden MRT chemicals: “natural flavors,” “spices,” “citric acid,” “soy lecithin,” “caramel color,” “modified food starch.” These are all tested on the MRT 176 panel.
4. Search the product on Wellbloom’s Food Checker to see exactly how many MRT triggers it contains.
5. When in doubt, skip it. You can always add it later in Phase 2 after confirming with your CLT.

Batch Cooking: Your Phase 1 Survival Tool

The single best thing you can do on Day 1 is batch cook. Spend 2-3 hours preparing food for the entire week. Here’s a template:

With batch cooking done on Day 1, weekday meals take 5 minutes: reheat protein + starch + vegetable, add salt and approved seasoning, eat. No decisions, no label reading, no temptation.
