Nourish Forward: The Free Symptom Tracker That Tells You If Nickel Is Your Problem
Here's a question I hear almost every week: "How do I know if nickel is actually causing my symptoms?"
The honest answer is that the gold standard diagnostic test — the double-blind, placebo-controlled oral provocation test — exists almost nowhere in the world. The standard skin patch test misses about 62% of people with systemic nickel allergy. Blood tests measure sensitization, not clinical disease. And hair mineral analysis, IgG panels, and bioresonance testing have no scientific validity for nickel allergy at all.
But there IS something you can do right now, for free, that uses the exact same benchmark the researchers use to confirm Systemic Nickel Allergy Syndrome: track your symptoms on a structured low-nickel elimination diet and measure your improvement over 30 days.
That's why I built Nourish Forward.
Why Tracking Matters: The 70% Benchmark
The BraMa-Ni protocol — the only published, validated low-nickel diet protocol — targets approximately 50 mcg of nickel per day and uses a specific improvement threshold to confirm SNAS: 70% reduction in symptom severity over 30 days.
In a study of 145 patients, this protocol achieved 94.4% sensitivity and 93.3% specificity for identifying systemic nickel allergy. That's better than many of the lab tests people spend hundreds or thousands of dollars on.
But here's the catch: you can only hit that benchmark if you're actually measuring your symptoms — consistently, week by week, with a baseline to compare against. "I think I feel a little better" isn't the same as "my overall symptom burden dropped 72% from Week 1." One is a feeling. The other is evidence you can bring to your doctor.
That's what Nourish Forward gives you.
What Nourish Forward Does
Nourish Forward is a free, browser-based symptom tracker designed specifically for people trying the low-nickel diet. It works on your phone or computer — no app store download required. You can even save it to your home screen so it works like a regular app.
Here's how it works:
Choose your symptoms. During setup, you pick up to 12 symptoms from preset categories — skin, gut, systemic, and ENT. Eczema, bloating, brain fog, headaches, joint pain, diarrhea, fatigue — they're all there. You can also create custom symptoms with your own name and emoji if you're tracking something specific.
Weekly check-ins. Once a week, open the tracker and rate each symptom on a scale of 1 (minimal) to 10 (severe) based on how it felt on average that week. Each symptom has a notes field where you can jot down what might have triggered it or how it felt. The whole check-in takes a few minutes.
Watch your progress unfold. After two or more check-ins, your Progress Dashboard shows your overall improvement percentage, how many weeks you've logged, your average symptom score, and your best week. You'll see charts showing your overall symptom burden trending over time, plus a symptom-by-symptom breakdown so you can spot which areas are improving fastest.
Share your data with your doctor or nutritionist. This is one of the most important features. You can download your progress graphic — a clean, shareable image showing your improvement — and bring it to your next appointment. You can also download individual symptom charts. Structured evidence helps your healthcare provider help you. Instead of saying "I think the diet is working," you can show them exactly how much each symptom has changed, week by week.
Set reminders so you never miss a week. After your first check-in, the tracker prompts you to set up push notifications or download a recurring calendar event. Consistency is everything — missing a week creates gaps in your data that make the 30-day assessment less reliable.
Your Data Is Completely Private
I want to be very clear about this: your data stays on your device. All your symptom scores, notes, and settings are stored locally in your own browser — on your phone or your computer. Nothing is sent to any server. No one else can see your data, including me.
If you choose to add a backup email address, the tracker sends a backup file directly to YOU after each check-in. That email is used only to send that file — it's not stored anywhere, not added to any mailing list, and not visible to anyone. It's a convenience feature so you have a copy of your own data, nothing more.
The only way anyone else sees your data is if YOU choose to share it — by downloading your progress graphic and sending it to your doctor, posting it in the community, or exporting a backup file.
How the 30-Day Protocol Works
The structured elimination diet that Nourish Forward is built to track follows the same approach validated in the research:
Target ~50 mcg of nickel per day for the first 30 days. This is the starting point used in the BraMa-Ni protocol. At this level, your plate naturally shifts toward animal proteins — the lowest-nickel whole food sources and the richest sources of L-glutamine and collagen peptides. These amino acids directly fuel the small intestinal cells that are most under attack from nickel, helping repair gut barrier integrity while you simultaneously reduce the nickel load.
My approach is focused on gut health — not just avoiding nickel, but actively supporting gut repair and reducing the permeability that lets nickel into systemic circulation in the first place. Less nickel in, better barrier repair, less nickel getting through, reduced immune activation, more healing.
After 30 days, check your Nourish Forward dashboard:
70% or better improvement — strong evidence that dietary nickel is a significant factor for you. This is the same benchmark used in oral provocation research to confirm SNAS.
Some improvement but less than 70% — nickel is likely part of the picture, but there may be other triggers alongside it.
No improvement — dietary nickel probably isn't your primary issue, and it's worth exploring other possibilities with your healthcare provider.

Don't Want to Calculate Nickel on Your Own?
I know what you're thinking — how am I supposed to know how many mcg of nickel are in my meals?
That's exactly why I wrote The Low Nickel Diet Cookbook. Every recipe includes the estimated mcg of nickel per serving, so you don't have to guess, look up values, or do any math. The recipes are built around my gut-health-first approach — focused on reducing gut damage and permeability while keeping you well-nourished and under your daily nickel target. It takes the guesswork out of the diet completely.

If you're wondering whether nickel is making you sick, you don't need a $2,000 blood test or a specialist who doesn't exist in your city. You need 30 days, a structured protocol, and a way to measure what changes. Nourish Forward gives you that measurement — for free, with complete privacy, using the same benchmark the research uses.
