Lime Juice

Why lime juice is rated low

Lime juice is rated low, and that rating is estimated from what the juice is made of rather than from a measured and weighed serving, so the ladder here is qualitative and reads "Any typical portion" at low. Juicing normally pushes a fruit upward, because it puts the sugars of several pieces into one glass and leaves the fibre behind, which is exactly why fruit juices so often run higher than the whole fruit. Lime is the unusual case where that does not bite, mostly because nobody drinks a glass of it. It is used as a squeeze, an acid, a seasoning, and at that scale it stays comfortably low. The thing to watch is not the lime but what else is in the bottle, because a great deal of what is sold as lime juice is a sweetened drink wearing a lime label.

What changes your risk

• Squeeze versus glass Juicing concentrates: the sugars of several limes end up in one measure with the fibre left behind. Lime stays easy because it is used as a splash of acid rather than drunk, so treating it like a beverage is the one way to change that picture.
• What the bottle actually contains Plain bottled lime juice is the same food as a fresh squeeze. Lime cordial, sweetened lime drink and cocktail mixers are usually built on high fructose corn syrup or another sweetener, and those are a different product with a different load.
• The drink around it Lime almost never arrives alone. It comes with agave syrup in a margarita, honey in a hot drink, or a fruit juice base in a punch, and those companions are what tip the glass.
• Cooking with it Simmering a lime dressing or reducing a marinade does not break down FODMAPs in anything else in the pan. Heat leaves them intact, so a sauce that started with onion and garlic is no gentler for having been cooked down.
• Stacking across the meal A low rating covers the food, not the sitting. Lime adds very little, but the dish it flavours, the rice or noodles under it and the drinks alongside all add to one running total.

What else works

Lime juice needs no replacement, so the point is what plays the same role and what only looks like it does. Lemon juice does the same job in a dressing, over fish or in a marinade, and plain vinegars bring acid without sweetness. Fresh herbs such as coriander, mint and chives, garlic infused oil, ginger, chilli and black pepper build the rest of the flavour that people usually reach for lime to carry. The lookalikes that do not inherit this rating: lime cordial and lime squash, sweetened margarita and mojito mixers, fruit punches and juice blends where lime is one small part, and anything sweetened with honey, agave syrup or high fructose corn syrup. A lime flavoured drink is not lime juice.

How to keep it low

Buy whole limes and squeeze them, which gives you a single ingredient with nothing to read. Limes that feel heavy for their size and have thin, slightly glossy skin give up the most juice, and rolling one firmly under your palm before cutting helps. If you juice several at once, freeze the juice in an ice cube tray and bag the cubes, so a squeeze is always to hand without buying a sweetened bottle. When you do buy bottled, look for one whose ingredients are lime juice and a preservative and nothing else, and keep it in the fridge once opened. Ordering out, a wedge of lime on the side is a safe request, while a house margarita mix or a cordial based soft drink is worth asking about.

Common questions

is lime juice low fodmap

Yes. Lime juice is rated low, an estimate based on its composition, and the qualitative ladder reads "Any typical portion" at low. That covers the squeeze, the dressing and the marinade.

how much lime juice can i use

No gram or millilitre figure is attached to lime juice here. The serving data is qualitative and "Any typical portion" comes in low, which covers normal seasoning use. It is not framed as a drink, and drinking it by the glass is outside what the data describes.

is bottled lime juice the same as fresh

Plain bottled lime juice with nothing added is the same food as a fresh squeeze. Lime cordial and sweetened lime drinks are not, since they are usually built on high fructose corn syrup or another sweetener, and those change the picture entirely.

can i drink lime in water on the elimination phase

A squeeze of lime in water fits the elimination phase, as does lime in dressings and marinades. Check that a bottled product has no added sweetener, and skip cordials and pre mixed drinks.
