White sugar
White sugar is plain refined sugar — no histamine content and no known effect on histamine release or breakdown.
White sugar is one of the most refined pantry staples, stripped down to pure sucrose with nothing else going on.
-
No histamine involvement — it doesn't contain histamine, doesn't prompt the body to release stored histamine, and doesn't interfere with the enzymes that break histamine down
-
Same picture as other plain sugars — white, raw, cane, beet — the histamine profile is essentially the same across plain, unfermented sugars
White sugar is a non-issue from a histamine perspective.
