Histamine reactions can feel random. A meal that sits fine on Monday leaves you flushed and bloated on Friday. A simple daily log is one of the most useful ways to turn that guesswork into a pattern you and your healthcare provider can actually see.
Our free OmneDiem Elimination Diet Tracker is an Excel workbook that walks you through a structured, provider-guided food test: log a normal baseline, remove suspected foods, bring them back one at a time, and let the tracker compare your symptom scores for you.

Talk with your healthcare provider or a registered dietitian before removing foods from your diet. Elimination diets are for suspected food intolerances, not food allergies. If you have ever had hives, swelling, wheezing, throat tightness, or trouble breathing after eating a food, do not test that food on your own; see an allergist. Not sure which you’re dealing with? Read The Difference Between a Food Allergy and Histamine Intolerance.Why Track Your Symptoms?
Think of histamine like water filling a bucket. Food, stress, poor sleep, hormones, and alcohol all pour in, while your DAO enzyme works to drain it. You notice symptoms when the bucket overflows, which is why the same food can seem fine one day and not the next (Histamine Bucket 101).
Memory is a poor witness for that kind of pattern. Writing down what you ate, when, and how you felt, every day, gives you and your provider real data instead of hunches (When Symptoms Feel Like a Random Guessing Game).
What’s Inside the Tracker
| Tab | What you do there |
|---|---|
| Start Here | Instructions, the 0–5 symptom scale, a color legend, and safety notes. |
| Food Plan | List the foods you and your provider suspect, why, and the dates you remove and reintroduce them. Ten common suspects are pre-filled, including aged cheese, alcohol, cured meats, fermented foods, and leftovers held more than a day. |
| Daily Log | Each day, pick a phase, list your meals and snacks, and score seven symptoms: bloating, abdominal discomfort, loose stools, nausea, heartburn, head pressure, fatigue, which add up to a daily total. |
| Reintroduction | Test one food at a time: amount eaten, symptoms noticed, a 0–5 score, and hours after eating. |
| Summary | Calculates automatically. Compares your average symptom scores across baseline, elimination, and reintroduction, overall and by symptom. |
Sand-shaded cells are where you type; white cells calculate on their own. Gray example rows show you how to fill things in and aren’t counted.
How to Use It: Four Phases
- Make your Food Plan. With your provider, list the foods or food groups you suspect and why. For histamine, common candidates include aged cheese, wine and beer, cured meats, fermented foods, and leftovers (Foods High in Histamine).
- Log a baseline. Eat as you normally do for about a week. Choose “Baseline” in the Daily Log and record every meal, snack, and drink, plus your symptom scores.
- Eliminate. Remove the suspected foods for 2 to 4 weeks, or as your provider advises, and keep logging under “Elimination.” Our Low-Histamine Diet guide can help with meal ideas.
- Reintroduce one food at a time. Start with a small amount, record how you feel and how many hours later, and wait until you know how you responded before testing the next food. Stop and contact your provider if a reaction is strong.
- Review the Summary. The Summary tab compares your average daily symptom total by phase. A negative “Change vs Baseline” means lower average scores than your baseline. Bring the results to your provider to decide what to limit, avoid, or keep.
How to Score Your Symptoms
Use the same 0–5 scale every day so your numbers stay comparable from week to week.
| Score | Meaning |
|---|---|
| 0 | None |
| 1 | Barely noticeable |
| 2 | Mild |
| 3 | Moderate |
| 4 | Strong |
| 5 | Severe |
Tips for Spotting Histamine Triggers
- Log freshness, not just foods. Histamine can build as food sits, so note when a meal is leftovers or slow-cooked.
- Watch for stacking. Several moderate-histamine foods in one day can add up to a reaction no single food would cause.
- Note timing. Record roughly how long after eating symptoms started; it helps connect a reaction to the right meal.
- Write down the other faucets. Use the Snacks & Drinks column or a notes line for alcohol, a stressful day, short sleep, or your cycle (How Do You Reduce Histamine in the Body?).
- Remember histamine liberators. Some foods, like citrus and tomatoes, may prompt your body to release its own histamine (What Are Histamine Liberators?).
- Keep supplements consistent. If you take a DAO supplement, keep your routine the same across phases and note it, so you and your provider can read the results clearly.
Opening the Tracker in Excel, Google Sheets, or Numbers
- Microsoft Excel: download the file and open it. Save a copy under your own name before you start.
- Google Sheets: upload the file to Google Drive, open it with Google Sheets, then choose File > Save as Google Sheets for a private, editable version.
- Apple Numbers: open the downloaded file in Numbers; it converts automatically.
Where DAO Fits
Tracking helps you learn what fills your bucket. Diamine oxidase (DAO) is the enzyme that helps drain it by breaking down histamine from food in the digestive tract. Once you and your provider know your patterns, a DAO supplement taken just before a meal may support the breakdown of dietary histamine on days when your plate is harder to control.*

FAQ: Tracking Histamine Symptoms
Is the OmneDiem symptom tracker free?
Yes. The tracker is a free Excel download with no sign-up required. It also opens in Google Sheets and Apple Numbers.
How long should I track my symptoms?
The tracker follows a common structure: about 1 week of baseline, 2 to 4 weeks of elimination, then reintroduction one food at a time. Your provider may suggest a different timeline.
What symptoms does the tracker include?
The Daily Log scores bloating, abdominal discomfort, loose stools, nausea, heartburn, head pressure, and fatigue on a 0 to 5 scale, and adds them into a daily total.
How do I reintroduce foods after an elimination diet?
Bring back one food at a time, starting with a small amount. Record what you ate, any symptoms, a 0 to 5 score, and how many hours after eating they appeared. Wait until you know how you responded before testing the next food.
Can I use the tracker for food allergies?
No. The tracker is for suspected food intolerances. Food allergies can be serious and should be diagnosed and managed by a medical professional. Call 911 if you suspect anaphylaxis.
Should I keep taking DAO while I track?
Talk with your provider. If you take a DAO supplement, keeping your routine consistent across phases, and noting it in your log, makes your results easier to interpret.*
