Mango

Why mango is rated high

Mango is high FODMAP at 1 cup (150g), and the reason is excess fructose. Mango holds more fructose than glucose, and fructose without enough glucose alongside it is absorbed slowly and incompletely by many people with IBS, which is what pushes a cup of chopped mango into the high range. The published data for mango tests one serving, 1 cup (150g), and that serving is high, so there is no lower rung on the ladder and no smaller tested portion of mango to quote.

What changes your risk

• Excess fructose is the mechanism, not the sugar total What matters here is the balance between fructose and glucose in the fruit, which is why mango behaves differently from fruits that are just as sweet.
• One tested serving, and it is high 1 cup (150g) is the only published serving for mango and it lands high. Nothing smaller has a tested level, so there is no tested amount to work from.
• Drying concentrates it further Dried mango has the water taken out and the sugars left behind, so the chewy strips are a more concentrated version of a fruit that is already high. Drying moves it in the wrong direction, never the right one.
• Smoothies and juice make it worse A mango smoothie or a glass of mango juice puts the sugar of several pieces of fruit into one drink and leaves the fibre behind, so the load arrives faster and larger than it would from eating the fruit.
• Fructose stacking at the same meal Honey, agave syrup, high fructose corn syrup, apple and watermelon all draw on the same subgroup. A mango smoothie sweetened with honey is two fructose sources in one glass.

Swaps

Plenty of tropical sweetness is available without the excess fructose. Pineapple and cantaloupe are the closest in flavour and texture for fruit salads, salsas and smoothie bases, and kiwi, oranges, mandarins, strawberries, grapes or a firm just-yellow banana round out the same role. For a mango salsa over fish or chicken, diced pineapple with bell pepper, cucumber, lime and the green tops of spring onions gives you the sweet and sharp contrast the mango was providing. When a dressing or marinade calls for mango chutney, maple syrup or rice malt syrup with a splash of vinegar does the sweetening. Skip honey and agave syrup here, because they sit in the same subgroup as the mango you are replacing.

How to lower the load

Mango is more common in prepared food than most people expect. Check smoothie blends and juice bars, mango lassi, salsas and chutneys, sticky rice desserts, kombucha and iced tea flavours, fruit yoghurt tubs, fruit cups and dried mango strips. At a smoothie counter it is worth asking what is actually in the house tropical blend, since mango is usually the base rather than a listed extra. If you are cooking for a table, serving the mango on the side rather than mixing it through a shared salad or salsa keeps it out of everything else on the plate.

Common questions

how much mango can i eat on a low fodmap diet

The published data gives one serving for mango, 1 cup (150g), and that serving is high in excess fructose. No smaller portion has a tested level to quote as low.

is mango high in fructose

Yes. Mango carries more fructose than glucose, and that imbalance, called excess fructose, is the subgroup behind its rating.

is dried mango any better than fresh mango

No. Drying removes the water and concentrates the sugars, so dried mango runs in the same direction as fresh mango rather than a gentler one.

what fruit can i use instead of mango in a smoothie

Pineapple and cantaloupe give the closest tropical sweetness, with kiwi, strawberries or a firm just-yellow banana to fill it out. Sweeten with maple syrup rather than honey or agave syrup.
