Corn Thins
Serving sizes
Corn Thins changes rating with portion size. These are the amounts tested in the literature behind our ratings.
- 2 thins (11.6g)
- 4 thins (23g)
Corn Thins are Low FODMAP at a small serving, staying gentle when you keep to 2 thins (11.6g).
- At 2 thins (11.6g) they carry no elevated FODMAP subgroups, so they sit comfortably in the low range for most people.
- As the stack grows, the overall FODMAP load builds and the level climbs to moderate, so it is the quantity rather than any single subgroup that tips the balance.
Enjoy them as a light, crunchy base for a low-FODMAP topping and keep to the tested serving to stay comfortable.
Why corn thins is rated low
Corn thins are low FODMAP at 2 thins (11.6g), and the tested record shows no raised FODMAP subgroup at that serving, which is why they turn up so often as a cracker replacement. The ladder has two rungs and they are close together: 4 thins (23g) is moderate. So this is a genuine low option with a real cap, not an unlimited one. In practice the topping usually decides how the plate lands, because the thins themselves are doing very little.
What changes your risk
- The height of the stack Two thins is the tested low serving and doubling it to 4 thins (23g) is moderate. That is the whole ladder, so counting them out is the single most effective thing you can do.
- What goes on top The topping is often the bigger load. Honey, hummus made from chickpeas, onion or garlic dip, ordinary yoghurt and cream cheese all push the plate out of range no matter how few thins are underneath.
- The rest of the meal around them A low rating applies to the serving, not the sitting. Corn thins alongside a lunch that is already near its limit contribute to the same total, so they work best as the light part of a plate rather than an extra on top of a full one.
- The flavoured versions are a different food Seasoned corn thins have their own tested ladder and their own ingredient list, which may include onion powder, garlic powder or added fibres. Do not carry the plain serving across to them.
- Keeping them crisp changes nothing about the FODMAP load Toasting them, storing them airtight or eating them stale makes no difference to the carbohydrates. Only the count and the toppings move the number.
What else works
Plain rice cakes, gluten free crackers, polenta chips and oatcakes made without honey all fill the same crunchy base role and are low FODMAP at sensible servings. For toppings that keep the plate honest, peanut butter, hard cheeses such as cheddar, parmesan or swiss, sliced egg, firm tofu, cucumber, bell pepper, baby spinach or strawberries with a drizzle of maple syrup all work. The lookalikes to avoid are wheat crackers, rye crispbread and wholemeal crispbreads with added inulin or chicory root fibre, because they are not equivalent despite sitting on the same supermarket shelf.
How to keep it low
Count the thins onto a plate before you start topping them, because they are light and thin enough that four disappear without feeling like a second helping, and four is already the moderate rung. Buy the plain version rather than the seasoned one when you have the choice, since plain has the simpler ingredient list. They go soft quickly once the pack is open, so an airtight container or a clip on the sleeve keeps them worth eating and stops you working through the packet just to use them up. Building the topping first and the base second also helps, since a generous spread over two thins feels more like a snack than a bare stack of four.

Yes. At 2 thins (11.6g) they are low FODMAP, with no raised subgroup recorded at that serving.

Two. The tested data puts 2 thins (11.6g) in the low range and 4 thins (23g) in the moderate range.
what can i put on corn thins that is low fodmap
Peanut butter, cheddar or another hard cheese, egg, cucumber, bell pepper or firm tofu all work. Honey, hummus and onion or garlic dip do not.
