Grade B — Moderate FODMAP Sorbitol

Do Peaches Trigger IBS?

It Depends

It depends on the portion. A small amount of peach (about half a medium peach or 75g) is low FODMAP, but a full peach contains enough sorbitol to trigger symptoms. Canned peaches in syrup are worse due to added sugars. Stick to small fresh portions for the safest option.

What Makes Peach Problematic for IBS

Peaches contain sorbitol, a sugar alcohol that is dose-dependent. Small portions are well tolerated, but the sorbitol accumulates quickly with larger servings.

How it works

Sorbitol in peaches is slowly absorbed and draws water into the intestine via osmosis. In larger amounts, unabsorbed sorbitol reaches the colon where bacteria ferment it, producing gas and bloating.

Common Symptoms

Symptoms from peaches are typically dose-dependent. A small portion may cause no issues, while a full peach can trigger bloating, gas, and loose stools within a few hours.

Portion Thresholds

⚖️

Safe Portion

Half a medium peach (75g)

Research Reference

Monash University: Half a peach (~75g) is low FODMAP. A whole peach is moderate to high FODMAP.

💡

Practical Tip

Dried peaches and peach nectar are high FODMAP due to concentration. Canned peaches in heavy syrup add extra fructose — choose fresh when possible.

Frequently Asked Questions

Are peaches low FODMAP?

In small portions, yes. Half a peach (75g) is low FODMAP, but a whole peach moves into moderate territory due to sorbitol content.

Are canned peaches safe for IBS?

Canned peaches in natural juice may be okay in small amounts, but those in heavy syrup add extra sugars that increase the FODMAP load. Fresh is best.

Can I eat nectarines instead?

Nectarines have a similar FODMAP profile to peaches. Small portions may be tolerated, but larger amounts contain significant sorbitol.
