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.

August 16, 2026

Sulfites are added to food. They are preservatives, so they show up in processed foods, drinks and anything that needs to be kept from browning or spoiling, and hardly at all in fresh produce.

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. 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 treat this as a list to know, 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 40+ other trigger criteria.

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. You get the specific pattern, down to which drinks and which days.

It takes seconds a day, and the preservative stops being invisible.

Your food, broken down

Meals become ingredients and sensitivity profiles: histamine, salicylates, FODMAPs, allergens, and even the additives on packaged food.

Everything in the same journal

Symptoms, supplements, sleep, stress, exercise and mood, beside what you ate.
