Prune juice
Prune juice may be moderately problematic — dried fruits concentrate natural compounds, and some people with histamine intolerance report difficulty with them.
Prune juice is made from dried plums, and the drying process can concentrate compounds that some people find reactive.
-
Drying and concentration — when fruit is dried, its natural compounds (including any histamine-adjacent substances) become more concentrated than in fresh fruit, which may explain why dried fruits are more commonly reported as problematic
-
Not well-studied — prune juice doesn't have a strong established mechanism in histamine intolerance literature, but reports of sensitivity to dried fruits are common enough to warrant moderate caution
Fresh plum juice, if available, would likely be a gentler alternative than prune juice.
