Spelt Bread (100%)

Low FODMAP

Serving sizes

Spelt Bread (100%) changes rating with portion size. These are the amounts tested in the literature behind our ratings.

  • 2 slices (52g) Low
  • 5¾ slices (150g) Moderate

100% Spelt Bread stays Low FODMAP at a sensible serving, making it a lovely everyday bread choice.

  • At 2 slices (52g) the overall FODMAP load sits comfortably in the low range, so it tends to be well tolerated for most people following the low-FODMAP approach.
  • As you work up to larger servings the overall FODMAP level rises into the moderate range, since the total load simply adds up the more you eat in one sitting.

Keeping to around 2 slices at a time is an easy way to enjoy spelt bread with your favorite toppings.

Why spelt bread (100%) is rated low

Bread made entirely from spelt flour tests low at 2 slices (52g), with no raised FODMAP subgroup recorded, and it climbs to moderate at 5¾ slices (150g). Two slices is the everyday sandwich or toast serving, which is what makes this loaf so useful: the tested amount matches the way people actually eat bread. The ladder also shows that there is real room between low and moderate, so a normal lunch is comfortable while a day built around bread at every meal is a different matter. How the loaf was made matters as much as the flour on the label, because a long, traditional fermentation and a fast factory rise leave very different loaves behind.

What changes your risk

  • Slices, not loaves 2 slices (52g) is low and 5¾ slices (150g) is moderate. A sandwich sits comfortably in the low range, while toast at breakfast plus a sandwich plus bread with dinner is a different total altogether.
  • Traditional sourdough versus a fast yeasted loaf a long, traditional sourdough fermentation gives the starter hours to break down much of what a quick rise leaves intact, which is why traditional sourdough spelt is treated differently from ordinary yeasted bread. A supermarket loaf sold as "sourdough flavoured" and proved in a couple of hours is not the same thing.
  • How thick the slice is cut the tested serving carries a weight as well as a slice count. A thick bakery cut weighs considerably more than a standard sandwich slice, so two slices off one loaf are not the same as two off another.
  • What goes on top the bread is often the innocent part of the meal. Honey, onion-based chutneys and relishes, hummus and garlic spreads bring their own load. Peanut butter, hard cheese such as cheddar, eggs and plain meats do not.
  • Added fibre in the loaf bakery and supermarket loaves sometimes have inulin or chicory root fibre added for texture or fibre claims, which is not part of what was tested here. The ingredient list will say.

What else works

If you want to rotate breads, gluten free bread and traditional sourdough wheat bread both fill the sandwich role at their own tested servings, and oats, rice, polenta, quinoa and buckwheat cover the wider starchy base at breakfast and dinner. Ordinary yeasted wheat bread, rye bread, wheat rolls, naan and pita are not stand-ins for this loaf, and neither is a multigrain loaf whose ingredient list leads with wheat flour. A loaf where spelt is only part of the flour blend is a separate entry with its own tested servings, so do not read this rating onto it.

How to keep it low

Ask the bakery how long the dough is fermented, since a genuine long fermentation is something bakers are usually pleased to talk about, and a loaf that goes from mix to oven in a couple of hours is a different product regardless of what the label says. Check the ingredient list for added inulin or chicory root fibre. Weigh a couple of slices off your usual loaf once, so you know how your bakery's cut sits against 2 slices (52g), and then you can go by eye afterwards. Freezing the loaf sliced makes portioning easier, though freezing does not change the FODMAP content, it only stops the loaf going stale before you get through it.

Common questions

is 100% spelt bread low fodmap

Yes, at 2 slices (52g), which is a normal sandwich serving. It moves to moderate at 5¾ slices (150g).

how many slices of spelt bread can i eat

2 slices (52g) tests low. By 5¾ slices (150g) it is moderate, so a sandwich is comfortable while bread at every meal of the day is worth spreading out.

is sourdough spelt bread different from ordinary spelt bread

Yes. A long, traditional sourdough fermentation gives the starter time to break down much of what a fast yeasted rise leaves behind. A loaf labelled sourdough but proved quickly does not get the same benefit.

can i eat spelt bread during the elimination phase

100% spelt bread at 2 slices (52g) is suitable during the elimination phase. Watch the toppings, since honey, onion relishes and garlic spreads bring their own load. Tolerance varies, and reintroduction is best worked through with a dietitian.
