The smell is strong enough that hotels and trains ban it.
Much richer and fattier than other fruits.
The spikes are sharp — this one really does need care.
Heavy, spiked, and famous for its smell. Inside is soft yellow flesh with the texture of custard.
Known to botanists as Durio zibethinus.
Durian is the one fruit that's genuinely calorie-dense. A single serving can carry as much energy as a meal, which is worth knowing before a second helping.
Genuinely nourishing for someone who is underweight or losing appetite — a rare fruit with fat, fibre and real calories. For everyone else, the portion is the whole story.
It was used: rich in potassium, which matters for blood pressure. Provides B vitamins, including thiamin and folate.
The tree is a tall rainforest species that can reach forty metres, related to okra and cotton rather than to any orchard fruit. Its pale flowers open at night and are pollinated by bats. Each fruit hangs directly from a thick branch and can weigh three kilograms, so a whole one is never picked by hand from above — it's caught, netted, or gathered after it drops. The husk is divided into five chambers, and the sharp pyramid-shaped spines are what the Malay word duri, meaning thorn, refers to.
Family: Malvaceae (mallow family).
Persian temperament: Hot & Moist (3rd degree). Southeast Asian practice calls durian strongly heating and pairs it with mangosteen or salted water to settle the body afterwards.
Durian isn't part of classical Persian medicine. South-East Asian tradition reads it as strongly heating, and pairs it with cooling mangosteen or with salted water drunk from the empty shell. That pairing is custom.
Eaten with mangosteen, or followed by salted water, to offset its supposed heating effect.
Called the king of fruits across Malaysia, Indonesia and Thailand, where the season is a public event and prized varieties sell for extraordinary prices. The ban on carrying it in hotels, taxis and metro carriages is real and widely posted.

What studies in people show
Durian extract inhibits aldehyde dehydrogenase activity, the biochemical basis of the alcohol reaction.Moderate evidence
Durian is exceptionally high in sugar, potassium and calories compared with other fresh fruit.Strong evidence
Wear gloves or use a folded cloth; the spikes puncture skin easily.
Cut along the natural seams at the base and prise the segments apart.
Freeze leftovers in a sealed box — it will scent an entire fridge otherwise.
Fresh, chilled, eaten by hand from the chamber.
Frozen is the texture becomes like ice cream and is genuinely good.
In the kitchen: cooked into South-East Asian sweets and sticky-rice dishes. Buy it already opened and packed if you're trying it for the first time.
Serve cold; chilling softens the smell considerably.
Treat one or two pieces as a dessert.
Mangosteen
The traditional counterweight. Locals eat one after the other, cooling fruit after heating fruit.
Sticky rice
Durian with sticky rice and coconut milk is a set dish across Thailand, and the rice tempers the richness.
Coconut
Coconut milk carries the flavour and softens it. Which helps if you're new to the fruit.
Salt
A pinch of salt on the flesh cuts the sweetness. It is a common trick and it works.
The seeds are toxic raw. They are eaten in some regions only after thorough cooking.
It is high in potassium. People with kidney disease who are told to limit potassium should avoid it.
The spikes are sharp enough to injure. Whole fruit is normally handled with gloves.
It is high in calories and sugar. People managing diabetes or weight should treat a serving as dessert, not fruit.
Alcohol — Durian compounds inhibit the enzyme that clears acetaldehyde, and the combination is widely reported to cause flushing, nausea and racing heartbeat. This is the one interaction to take seriously. (high concern)
Diabetes medicine — Durian is one of the highest-sugar fruits eaten. A single large segment can be the sugar of a full meal. (moderate concern)
Blood pressure medicine — The fruit is high in potassium, which matters if you have kidney disease or take a potassium-sparing diuretic (makes you pass more urine). (moderate concern)
Pregnancy and breastfeeding
Small amounts are fine. Durian is very high in sugar and calories, so it counts against a gestational diabetes plan more than most fruit does.
Children
Rich and sweet, and most children either love it or refuse it outright. Give a small piece, and not late in the evening.
Older adults
Soft and needs no chewing, but heavy in sugar and potassium. If you have kidney disease or diabetes, treat it as an occasional pleasure rather than a fruit bowl staple.
Spring
Little good fruit. Frozen whole durian keeps its texture better than chilled fruit flown in green.
Summer
The Thai and Malaysian season. This is when to eat it, and when the price falls.
Autumn
A shorter second season in parts of the region. Fruit is often smaller and more intensely flavoured.
Winter
Out of season everywhere. Frozen paste is the honest choice.
Does it really smell that bad?
It is very strong: onion, gas and sweet custard at once. Many people who dislike the smell still like the taste.
How much is a serving?
Two or three segments, roughly 100 grams. That is already around 150 calories.
Why is it banned in hotels and trains?
The smell clings to fabric and air conditioning for days. The bans are about the smell.
