Tahini

Tahini is low in histamine. It is simply ground toasted sesame seeds, with no fermenting, curing, or aging involved, so most people with histamine intolerance tolerate it well.

Why tahini is rated low

Tahini is nothing but sesame seeds roasted and milled into a paste. There is no fermentation or aging step where histamine-forming bacteria could get to work, so plain tahini stays low. The things worth watching are quality issues rather than histamine: a jar that has gone rancid or grown mold is a food-quality problem, and a small number of people are simply sensitive to sesame itself.

What changes your risk

• Freshness of the jar: sesame paste is high in oil and can turn rancid over time, which is a taste and quality problem, so buy jars you will actually finish and store them well.
• Mold: if you ever see mold in the jar, throw the whole thing out rather than scooping around it.
• Added ingredients: plain tahini is just sesame, but prepared sesame sauces and sweets can add lemon, garlic, or other things that change the picture, so check the label.
• Storage: keep opened tahini capped, and refrigerating it after opening slows it going off, though it will firm up and need a stir.
• Sesame sensitivity: separate from histamine, some people react to sesame itself, which is worth knowing if tahini doesn't sit right.

What else is safe

If you get on well with tahini, you are likely fine with other seed-based spreads such as fresh sunflower seed butter or pumpkin seed butter, which many people tolerate well. The lookalikes to be careful with are the nut butters that share the shelf: peanut butter is a histamine liberator and sits high, and cashew and walnut butters are ones many people with histamine issues avoid. Sesame sauces mixed with lemon or garlic are also a different story than plain tahini.

How to enjoy it

Buy plain tahini with sesame as the only ingredient, give it a good stir to mix the separated oil back in, and keep it capped in the fridge once opened so it stays fresh. Use it in dressings, drizzled over roasted vegetables, or blended into a dip; if you are making a tahini sauce, thin it with water rather than piling on lemon juice, since citrus is a histamine liberator for a lot of people.

Common questions

Is hummus low histamine too?

The chickpeas and tahini are the milder part, but classic hummus usually has lemon juice and often garlic, which bother a lot of people, so a homemade batch without the lemon tends to be gentler.

Does rancid tahini have histamine?

Rancidity is an oil-quality issue rather than a histamine one, but off tahini tastes bitter and is worth tossing regardless.
