Rum

Why rum is rated low

Rum tests low at 1 shot (30mL), and no FODMAP subgroup is recorded as raised for it at that serving. That reading describes the spirit on its own, which is rarely how rum is drunk. Most rum arrives in a tall glass with cola, fruit juice or a sweet syrup, and those decide the FODMAP load far more than the spirit does. The other way past the serving is volume: doubles, cocktails built on two or more shots, and a long evening of rounds all leave 1 shot (30mL) behind, and no larger amount has been tested here.

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.
• The syrups do the damage Cocktail sweeteners are where the trouble usually hides. Honey syrup and agave syrup are not low FODMAP, and a bar's own sweet mix can contain either.
• Fruit juice mixers Pineapple, orange and lime are workable, while apple, pear and mango juices are not. Any juice concentrates the sugars of several pieces of fruit into one glass with the fibre left behind, so a juice-heavy glass is a bigger load than the fruit sounds.
• Spiced, coconut and cream bottles Spiced rums are flavoured products and cream liqueurs are dairy drinks. Neither is the plain spirit the data tests, so read what is in the bottle.
• What the drink sits alongside Rum carries no raised subgroup of its own, so stacking here is the whole evening's total rather than one carbohydrate compounding. Bar snacks seasoned with onion and garlic powder are the usual unlisted contributor.

What else works

A single 1 shot (30mL) of rum over ice with soda water, fresh lime and mint leaves is about as close to the tested serving as a mixed drink gets, and pineapple or orange juice in a modest amount is a reasonable fruit note. Gin and vodka are also low at 1 shot (30mL) on their own records, and beer is low at 1 can (375mL). Skip the drinks that only look similar: rum punch built on apple, pear or mango juice, coconut cream and cream liqueur bottles, premixed mojito and daiquiri mixes sweetened with honey or agave, and sugar-free mixers listing sorbitol, mannitol, xylitol, maltitol or isomalt.

How to keep it low

Order rum as a single with soda and lime rather than off the cocktail list, since a named cocktail rarely tells you how many measures went in. At home, use a jigger and build the drink tall with soda water and ice so it lasts, which keeps the spirit at 1 shot (30mL) while the glass still feels like a drink. Muddling fresh lime and mint yourself avoids the bottled sweet mixes entirely. Keep plain white or dark rum as your default bottle and treat spiced, coconut and cream versions as separate purchases with their own labels to read.

Common questions

how much rum is low fodmap

1 shot (30mL) is the tested serving and it reads low. Cocktails often contain more than one measure, and larger amounts have not been tested here.

is spiced rum low fodmap

Spiced rum is a flavoured product rather than the plain spirit the data covers, so the 1 shot (30mL) reading does not describe it. Check the ingredients on the bottle.

what can i mix with rum on a low fodmap diet

Soda water with fresh lime and mint is the simplest choice, and pineapple or orange juice works in a modest pour. Leave out apple, pear and mango juices and syrups sweetened with honey or agave.

can i drink rum during the elimination phase

Yes, at 1 shot (30mL) of the plain spirit. Tolerance is individual, and alcohol itself can be uncomfortable for some people regardless of FODMAPs.
