Tomato Salsa

High FODMAP

Serving sizes

Tomato Salsa 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 Moderate
  • Moderate serving High
  • Large serving High

Tomato salsa lands High FODMAP, since it almost always starts with a base of onion and garlic that overshadows the tomatoes themselves.

  • The Fructans from onion and garlic are the drivers here, and they climb fast: even a small serving is moderate, and a moderate to large serving is high.
  • Salsa recipes vary, but onion and garlic are so standard that most versions carry the same load; a chunky salsa without those aromatics is a different story.

For a dip that scratches the same itch, try making your own fresh tomato salsa using garlic-infused oil and just the green tops of spring onions for that savory kick.

Why tomato salsa is rated high

Tomato salsa is rated high, and the tomatoes are not the reason. The rating here is estimated from the recipe rather than from a weighed serving, and almost every salsa worth the name starts with chopped onion and garlic. Those bring Fructans, and fructans are what drive this page from top to bottom. The ladder puts a Small serving at MODERATE, a Moderate serving at HIGH and a Large serving at HIGH, which means the smallest amount tested is already moderate and there is no rung where salsa comes in low. Dipping lightly is not a strategy with this one. Making it yourself, without the bulb, genuinely is.

What changes your risk

  • Serving size The climb starts above the line. A Small serving already reads MODERATE and a Moderate serving is HIGH, so there is no helping on this ladder that lands low.
  • Stacking with other fructan sources Salsa rarely turns up alone. Wheat tortillas or wheat crackers, onion in the filling and garlic in the beans all carry fructans too, and a meal built around a shared bowl of dip adds them all up across one sitting.
  • The onion and garlic are chopped in, not on the side You cannot pick them out and you cannot cook them out. Heat does not break fructans down, so a cooked or jarred salsa carries the same load as a fresh one made the same way.
  • Garlic-infused oil changes the whole recipe Fructans do not dissolve into oil, so infusing oil with garlic and then discarding the solid pieces gives you the flavour without the fructans. This is what makes a homemade salsa possible at all.
  • Green tops instead of bulbs The green tops of spring onions and chopped chives carry the onion note without the bulb that causes the trouble. Leek leaves work the same way when you want something a little sweeter.

Swaps

A homemade fresh salsa is the honest answer here, and it is not a compromise: chopped tomato, diced bell pepper and cucumber for crunch, fresh chilli for heat, lime juice, plenty of coriander, a good pour of garlic-infused oil and the green tops of spring onions for the savoury lift. A pinch of asafoetida stands in for the deeper onion note if you want it. What will not work is swapping to a jarred salsa verde, a pico de gallo from the deli counter or most guacamole from a tub, since all of those usually start with the same chopped onion and garlic. If you want a dip that needs no rebuilding at all, a tomato and cucumber chop dressed with lime and infused oil fills the same spot on the table.

How to lower the load

Reading jars is mostly a losing game here, because onion and garlic sit near the top of almost every ingredient list, and restaurant salsa is made in large batches with both. Making a batch at home takes minutes and keeps in the fridge for a few days, and it tastes better cold than most jarred salsa does. Chop the tomatoes and drain off the watery juice before dressing them so the salsa does not go thin, and add the lime and infused oil just before serving. When you are out, a squeeze of lime and fresh chilli on the plate gets you most of the way to the same flavour without the bowl. If you bring your own to a gathering, bring enough to share so you are not eyeing the communal bowl.

Common questions

is tomato salsa low fodmap

No. It is rated high overall, because the onion and garlic in the usual recipe carry Fructans, and that outweighs the tomatoes.

how much salsa can i eat on a low fodmap diet

No serving on the ladder comes in low. A Small serving is MODERATE and a Moderate serving is HIGH, so scaling down the scoop does not bring it into the clear.

is salsa high in fructans

Yes. Fructans are the only subgroup recorded for it, and they come from the chopped onion and garlic rather than from the tomatoes.

can i make low fodmap salsa at home

You can, and it is the practical fix. Leave out the onion bulb and fresh garlic, and build the flavour from garlic-infused oil, the green tops of spring onions, chilli, lime and coriander instead.
