Cheese

Cheese as a whole sits in the moderate range, but the type is everything: fresh cheeses like fresh mozzarella and fresh goat cheese run low, cultured fresh cheeses like cream cheese and cottage cheese sit at moderate, while aged and blue cheeses are among the highest-histamine foods there are. The single thing that decides it is how long the cheese was aged.

Why cheese is rated moderate

Histamine in cheese comes from aging. Cheese is protein-rich, and during weeks or months of ripening the bacteria and cultures in it break that protein down and produce histamine along the way. A fresh cheese is made and eaten within days, so it has had almost no time to build any. The more a cheese is aged, cultured or ripened, the more histamine tends to accumulate, which is why a young cottage cheese and an aged cheddar sit at opposite ends despite both being 'cheese'.

What changes your risk

• How long it aged — this is the main lever. Fresh, unaged cheeses (fresh mozzarella, paneer, fresh goat cheese) have had no ripening time and stay low, and cultured fresh cheeses (cottage, cream cheese) sit at moderate, while cheddar, parmesan, gouda, gruyere and anything hard or long-ripened climb steeply.
• Blue and mold-ripened types — blue cheese, brie, camembert and similar rely on heavy mold and bacterial activity to develop, which pushes them to the very top of the histamine list. These are best avoided rather than moderated.
• Freshness and storage of fresh cheese — because fresh cheese is a protein food, keep it cold, sealed, and eat it within a few days of opening. Left warm or long past its date, even a fresh cheese can climb.
• Portion — a small amount of a genuinely fresh cheese is very different from a plate of aged, so the type plus the amount together shape how a serving lands.
• Processed and 'melting' cheeses — many processed cheese products are built on aged cheese, so they carry that aging with them even when they taste mild.

Lower-histamine alternatives

If you want a cheese-like option that stays low, reach for the fresh end: fresh mozzarella, ricotta, paneer and fresh goat cheese are the reliable choices, and cultured fresh cheeses like cottage cheese and cream cheese sit a step up at moderate. Steer clear of the aged and mold-ripened crowd (cheddar, parmesan, gouda, gruyere, blue, brie, camembert, feta), which are high rather than moderate. For a savory topping without cheese at all, a little olive oil with fresh herbs works well.

How to lower the risk

When buying, read for 'fresh' or 'unripened' and check that it is sold cold and used quickly, not aged. At home, keep fresh cheese tightly wrapped and refrigerated, and finish an opened tub within a few days rather than letting it linger. If you see mold on a soft or fresh cheese, throw the whole thing out rather than cutting around it; only naturally hard cheeses can have a mold spot trimmed generously, and hard cheeses are the aged ones you are likely avoiding anyway.

Common questions

Is mozzarella high in histamine?

Fresh mozzarella is one of the lower-histamine cheeses because it is made and eaten young with no aging. Aged or smoked block mozzarella is a different story and runs higher.

Why is aged cheddar so much worse than cottage cheese?

Cheddar is ripened for months, and during that time the cultures break down its protein and build histamine. Cottage cheese is fresh and only briefly cultured, so it stays at moderate.

Is cream cheese OK for histamine intolerance?

Cream cheese is a cultured fresh cheese and sits at moderate: it has none of the months of ripening that make cheddar high, but it is not as plain as fresh mozzarella. Keep it cold, use it within a few days of opening, and watch out for blends with aged cheese or other flavorings mixed in.

Does melting or cooking cheese lower its histamine?

No. Heat does not remove histamine that has already formed during aging, so a melted aged cheese carries the same histamine as the unmelted one.
