Low sugar, high fibre, striking to look at — and mild enough to disappoint people.
Dragon fruit, or pitaya, is the fruit of a climbing cactus. It is notably low in sugar for
a tropical fruit and reasonably high in fibre, much of which comes from the small black
seeds.
The flavour is genuinely mild — closer to a subtle melon than anything
dramatic. People expecting the taste to match the appearance are usually
underwhelmed.
Red-fleshed varieties contain betacyanins, the same pigment family found
in beetroot. This can turn urine and stool pink, which is harmless and startles people
who do not expect it.

Ripe fruit gives slightly and the leafy scales start to dry at the tips.
Rock-hard fruit is underripe.
Chill it. Dragon fruit is considerably
better cold — the mild flavour needs the crispness.
Scoop it out with a
spoon, or cut in quarters and peel the skin back.
Red flesh will
colour your urine. This is betacyanin, it is harmless, and it passes within a
day.
The low sugar content relative to other tropical fruits is the main practical point —
around 8g per 100g against a mango's 14g. Combined with 3g of fibre, that gives it one of the
better sugar-to-fibre ratios of any tropical fruit.
The seeds are the fibre. They are
too small to notice and pass through intact, contributing insoluble fibre in the same way
kiwi seeds do.
Diabetes: whole fruit over juice, portion aware, and better eaten
with protein or fat than alone.
IBS: several fruits are high-FODMAP
and commonly trigger symptoms — tolerance is personal.
Kidney
disease: potassium may need limiting. Ask your doctor for your numbers.
