Rum

Why rum is rated high

Rum is high FODMAP at 1 shot (30mL), and excess fructose is the reason. Even a single measure carries enough of it to land above the line, and there is no smaller low serve to portion down to. That is before the mixer: most rum arrives in a tall glass with cola, fruit juice or a sweet syrup, and those often add more on top. Volume compounds it too, since doubles, cocktails built on two or more shots, and a long evening of rounds all multiply a load that already starts high.

What changes your risk

• Count the shots in the cocktail Plenty of rum drinks are built on more than one measure. A punch bowl or a double-pour tiki glass is several servings, not one, whatever the menu calls it, and each one starts high.
• The syrups add more Cocktail sweeteners are where extra load usually hides. Honey syrup and agave syrup are rich in excess fructose, and a bar's own sweet mix can contain either, stacking on top of the rum.
• Fruit juice mixers Apple, pear and mango juices are high in excess fructose themselves. Any juice concentrates the sugars of several pieces of fruit into one glass with the fibre left behind, so a juice-heavy rum drink stacks one excess fructose source on another.
• Spiced, coconut and cream bottles Spiced rums are flavoured products and cream liqueurs are dairy drinks. They are separate products with their own labels, and none of them get around the rum underneath.
• What the drink sits alongside Excess fructose adds up across an evening. Rum next to fruit-heavy cocktails, honey-glazed bar food or a mango dessert puts several excess fructose sources into the same few hours.

Swaps

If you want a spirit, gin, vodka and whiskey each come in low at a single shot on their own pages, and any of them with soda water, ice, fresh lime and mint gives you the same long, fresh drink a rum highball would. A plain lager or ale is another low option on its own page. For the flavour of a rum drink without the rum, soda water with muddled lime, mint and a little table sugar makes a decent virgin mojito. Skip the drinks that only look similar: rum punch built on apple, pear or mango juice, premixed mojito and daiquiri mixes sweetened with honey or agave, and spiced or coconut rum, which carry the same spirit underneath.

How to lower the load

When the round is rum-based, order a single gin, vodka or whiskey with soda and lime instead, since a named rum cocktail rarely tells you how many measures went in and every measure starts high. At home, keep a different plain spirit as the default bottle and use a jigger so a pour stays a pour. Muddling fresh lime and mint yourself avoids the bottled sweet mixes entirely, whichever spirit goes in the glass. If you do choose rum during reintroduction, treat a single measure with soda water as the whole drink and keep the rest of the evening light on fruit juice and honey.

Common questions

how much rum is low fodmap

There is no amount that comes in low. 1 shot (30mL) is already high, driven by excess fructose, and cocktails often contain more than one measure.

is spiced rum low fodmap

Spiced rum is a flavoured product built on the same spirit, so it does not get around the high rating for rum. Check the ingredients on the bottle for any added honey or fruit as well.

what can i mix with rum on a low fodmap diet

Rum itself is high at 1 shot (30mL), so the mixer cannot bring it down. If you want a mixed drink, gin, vodka or whiskey with soda water, fresh lime and mint is the low FODMAP route, and apple, pear and mango juices are worth avoiding either way.

can i drink rum during the elimination phase

Rum is high at 1 shot (30mL), so it does not fit the elimination phase. Gin, vodka or whiskey are the low options, and reintroducing rum later is something to plan with a dietitian.
