Luncheon meats
Pre-sliced and packaged processed meats are a consistent high-histamine category — curing and storage are the main drivers.
Luncheon meats are a broad category, but most share the same characteristics: cured, sliced, and stored — all of which raise histamine.
-
Curing is the foundation — nearly all luncheon meats are preserved through curing, which allows bacteria to produce histamine as part of the preservation process
-
Pre-sliced packaging keeps it climbing — once sliced and sealed, histamine continues to accumulate in the package, meaning older or near-expiry products typically carry more than fresh-sliced
Buying from a deli and consuming within a day or two tends to be better than pre-packaged sliced varieties.
