Tamarind

Low FODMAP

Serving sizes

Tamarind changes rating with portion size. Its rating is estimated from what it is made of, so the servings are described rather than weighed.

Small serving Low
Large serving Moderate

Tamarind is Low FODMAP in the small culinary amounts you use as a tangy fruit paste, since a little goes a long way for that sour-sweet flavor.

As an acidic fruit paste, tamarind stays comfortable at a small serving, but the overall FODMAP load builds up at a large serving, nudging it to moderate when used in concentrated amounts.
It shows up as pulp, paste, and concentrate, and a spoonful stirred into curries, chutneys, or dressings is exactly the kind of seasoning-sized use that keeps it gentle.

Use tamarind the way it shines, as a bright accent rather than a bulk ingredient, and you get all the flavor without the load.

Why tamarind is rated low

Tamarind is LOW on a low FODMAP diet at the seasoning sized amounts it is normally used in. No FODMAP subgroup is recorded against it, so there is no single carbohydrate driving the rating, and the rating itself is estimated from what tamarind is made of rather than from a measured serving. A "Small serving", the spoonful of pulp or paste stirred through a curry, a chutney or a dressing, reads LOW. A "Large serving", tamarind used as a bulk ingredient rather than an accent, climbs to MODERATE on overall load. Tamarind is a sour fruit paste, and the sourness is exactly why most recipes only ever ask for a little of it.

What changes your risk

Accent versus base A "Small serving" is LOW and a "Large serving" is MODERATE. Tamarind behaves as a flavouring, and the rating holds as long as it stays one. A dish where tamarind is the main body of the sauce is a different amount entirely.
Pulp, paste and concentrate are not the same spoonful Concentrate is reduced, so a spoon of it stands in for a much larger amount of pulp. Match the spoon to what the jar actually is rather than to what the recipe assumed.
What the sauce is built on The real risk with tamarind is rarely the tamarind. Ready made tamarind sauces, pad thai sauces, sambar and rasam mixes and bottled chutneys are usually built on onion and garlic, and those fructans have nothing to do with the fruit. Build the base with garlic infused oil, chives and the green tops of spring onions instead.
Sweetened tamarind products Tamarind candies, syrups and bottled drinks are carried by added sweeteners rather than by the fruit. Anything sweetened with honey, agave, high fructose corn syrup, or with sorbitol, mannitol, xylitol or maltitol is a separate question from the paste itself.
Stacking across the meal With no subgroup recorded for tamarind, what matters is the total FODMAP load of the whole plate. A low tamarind dressing on a salad that already carries onion, wheat or legumes is the combination to look at, not the tamarind.

What else works

Tamarind is already low as a seasoning, so the honest answer is that the paste itself rarely needs replacing. The swap that matters is the jar it comes in: a plain tamarind pulp or paste stirred into your own dish rather than a ready mixed sauce whose first ingredients are onion and garlic. When a bottled blend is out, garlic infused oil carries the savoury depth without the fructans, and chives, leek leaves or the green tops of spring onions rebuild the aromatics. The lookalikes that are not low are the convenience versions: bottled tamarind chutney, pad thai and sambar pastes, and sweetened tamarind drinks and sweets.

How to keep it low

Buy tamarind as a block of pulp or a plain paste and read the ingredients, because the short list is the whole point. Soak a piece of the block in hot water, press it through a sieve and freeze the strained pulp in an ice cube tray so one cube is one dish and the portion is decided before you cook. Add tamarind at the end and taste as you go, since the sourness builds and you will use less than the recipe suggests. In restaurants, tamarind on the menu usually signals a sauce, so ask about onion and garlic in it rather than about the tamarind.

Common questions

is tamarind low fodmap

Yes, tamarind is rated LOW overall at seasoning sized amounts. The rating is estimated from what tamarind is made of rather than from a measured serving.

how much tamarind can i use

A "Small serving" is LOW, which covers a spoonful stirred through a dish. A "Large serving" climbs to MODERATE, so tamarind works as an accent rather than a bulk ingredient.

is tamarind paste ok on the elimination phase

Plain tamarind pulp or paste at a "Small serving" is LOW, so it fits. Check the label first, because many tamarind sauces and chutneys carry onion and garlic.

what about tamarind chutney or tamarind candy

Those are different products. Bottled chutneys and sauces are usually built on onion and garlic, and tamarind sweets and drinks are carried by added sweeteners rather than by the fruit.

Tamarind is an estimated rating: it is inferred from the food's ingredients and composition and cross-checked, not measured directly in the papers below. The low, moderate and high cutoffs are still those of Varney et al. (2017).
