High-sulfite foods: the complete list
A preservative more than a food chemical - here's where sulfites hide, and why wine and dried fruit rank highest.
Unlike most food compounds, sulfites aren't something a food naturally grows - they're something added. They're preservatives, and that changes where they show up: not in fresh produce, but in processed foods, drinks and anything that needs to be kept from browning or spoiling.
If sulfites are something you react to, here's the complete list - and a plain explanation of what they are.
What sulfites are
Sulfites are a family of preservative additives - sulfur dioxide and various sulfite salts such as sodium and potassium metabisulfite.1
They're used widely in the food industry to stop browning, prevent oxidation and protect against microbial spoilage - which is why they cluster in wine and beer, dried fruit, pickled foods, condiments, and various processed products.1 Reactions to them are mostly non-allergic - more a chemical irritation than a classic immune allergy - and the best-known link is to asthma, where sulfites can provoke the airways in sensitive people.3 Because reactions are recognised, sulfites generally have to be declared on labels above a set threshold.2 (We cover the mechanism in sulfite sensitivity explained.)
The high-sulfite foods
Below is the full list of foods and drinks that carry a meaningful sulfite load - drawn directly from the Triggerbites ingredient database.
The pattern is clear: wine and beer, dried fruit, pickled foods, vinegars and condiments, plus some processed shrimp and meats. Fresh, unprocessed foods barely feature - because there's nothing there for a preservative to do.
It's a load, and it's dose-dependent
Like the other food-chemical sensitivities, sulfite reactions behave as a threshold - the amount matters, the food's acidity matters (more acid releases more sulfur dioxide gas), and how settled your asthma is on the day matters.1
So this isn't a list to fear wholesale - it's a list to be aware of, especially if you have asthma and notice reactions clustering around wine, dried fruit or processed foods.
Finding your pattern
The useful things to track are the high-sulfite foods and drinks you had, how much, the type of symptom (chest tightness and wheeze versus skin or gut), and the timing - sulfite reactions tend to come on fast.
Where Triggerbites fits in
This list comes straight from the food data inside Triggerbites, which tags every ingredient for sulfites alongside 20+ other compounds.
So when you log meals and drinks in plain language, Triggerbites extracts the ingredients, tags the sulfite load, and correlates it with your symptoms across time windows. Instead of vaguely blaming "wine," you get the specific pattern.
Triggerbites Features
- Log like you're texting: plain language, not database searches
- Automatic ingredient breakdown: we parse your entries into the basic components so you don't have to
- Built-in chemical tagging: FODMAP, histamine, salicylates, oxalates ++ more compounds flagged automatically
- Multi-window pattern recognition: correlations across same-day, next-day, and multi-day windows
- Reports you can share: something to take to a doctor or dietitian
It takes seconds a day, and it makes a hidden preservative visible.
For the science, see sulfite sensitivity explained and could it be histamine intolerance?
Live, love, log. 🧡
