Are pears high FODMAP?

The fruit that trips two wires at once

Pear is one of the foods that carries two FODMAPs in the same bite. It holds more fructose than glucose, what Monash calls excess fructose, and it is also rich in sorbitol, a sugar alcohol in the polyol group. Some pears add a little fructan on top. Most trigger fruits lean on a single FODMAP. Pear leans on two, sometimes three, which is why its low-FODMAP serving is so small: around 5g, a teaspoon, for a nashi pear in the Monash app.

Both main molecules move the same way through you. Your small intestine absorbs fructose best when matching glucose comes along to escort it across the wall, and in a pear the fructose outruns the glucose, so the leftover is poorly absorbed. Sorbitol is barely absorbed at all, and it competes with fructose for the same crossing. Picture a turnstile that only lets sugar through in pairs. The unpaired fructose and the sorbitol back up behind it, pull water in beside them, then pass to the colon where gut bacteria ferment them into gas. Water plus gas stretches the bowel wall, and a sensitive gut reads that stretch as bloating or cramping.

This is why pear often runs harder than apple, even though the two look like the same problem. Both carry excess fructose and sorbitol, but pear's sorbitol load is high enough that Monash never found a green serving for the whole fruit. The answer is a portion, not a yes or no. A teaspoon or two of pear stays under most people's line, while a whole one is high in both fructose and sorbitol.

Your pear line isn't on the chart

That 5g cutoff is a population average, the portion that sits under most people's threshold, not yours. Your real line is set by your own gut sensitivity, how fast food moves through you, and whether anything else fermentable arrived in the same window. It drifts with stress, sleep, and your cycle. Pear also rarely flares you alone. Its sorbitol stacks with the sorbitol in stone fruit, mushrooms, and avocado, and its excess fructose stacks with apple, mango, and honey, all drawing on the same budget. Some people handle a few slices on a salad. Others react to a quarter. The chart can't tell them apart.

The only way to find your number is to watch this specific food against how you actually feel a few hours later: same portion, noted, more than once. A correlation between pear and a rough afternoon is a lead worth testing, not a verdict. Logging pear against your symptoms, the way Bellyweather is built to do from a photo, tallies its fructose and sorbitol against everything else you ate, so a load you can't hold in your head becomes a number you can point at.

• Start with a small serve, a teaspoon or two of pear or a few thin peeled slices, and check how a few hours later feels before scaling up.
• Reach for a low-FODMAP swap when you want a whole piece of fruit. Kiwi, mandarin, or a firm unripe banana each carry far less of pear's two FODMAPs.
• Treat pear juice as a concentrated dose, not a gentle one. The fructose and sorbitol come without the fibre, so a small glass hits harder than a slice of fruit.
• Don't stack pear with other sorbitol or excess-fructose foods in one meal (apple, mango, stone fruit, mushrooms, or honey), since their loads add together.
