Serving size, prep, and portion notes for dragonfruit
Dragonfruit is the fruit of a climbing cactus rather than a tropical tree, and it grades like one of the quieter fruits: A for histamine, histamine liberation, tyramine, nickel, sulfites, glutamates, lactose and gluten, with FODMAPs the only borderline mark (B, and no individual FODMAP subgroup flagged). The thing most people actually arrive here searching for is not a trigger at all: red-fleshed varieties carry betacyanin pigments that pass through largely unchanged, so urine and stool can come out pink or red for a day. It is the pitaya equivalent of beeturia, it is harmless, and it is regularly mistaken for blood in urine or a gastrointestinal bleed. White-fleshed dragonfruit does not do it. The tiny black seeds are edible and are meant to be eaten with the flesh, the way a kiwi is.
Watch for
Red-fleshed dragonfruit can tint urine and stool pink or red for a day or two. This is pigment, not blood, and it clears once you stop eating it. Colour that persists several days after the last serving is a question for a doctor, not a diary entry / Graded B on total FODMAPs with no single subgroup flagged, so an ordinary serving suits most sensitive guts and a whole large fruit in one sitting is where the complaints start / High in fibre and packed with seeds, which can loosen stools on volume alone. That effect gets logged as a food reaction more often than it deserves / Salicylate and oxalate content are both unrated here. If you are tracking either one, treat dragonfruit as an open question and test it deliberately rather than filing it as clear
