Pectin

Pectin is notable for FODMAPs and oligosaccharides. Clear on histamine, tyramine, salicylate, sucrose, lactose, sorbitol, fructose, nickel, oxalates and gluten.

Pectin contains only low levels of FODMAPs. Pectin is extracted from citrus peel and apple pomace. It ferments, which is why it is low rather than none - but it is a long-chain polysaccharide used at well under one percent, and the two together keep it here. The gums that sit higher on this axis do so because they are used in larger amounts or ferment faster. The dependence on serving size comes from Gibson and Shepherd, who built this approach: what these carbohydrates do is deliver fermentable substrate and water to the end of the small intestine, so the quantity decides the distension. Their trial also found that restricting them GLOBALLY works where restricting them one at a time does not.

Pectin contains only low levels of oligosaccharides. Pectin is a long chain - a polysaccharide of hundreds of units, not the three to ten of an oligosaccharide - and it is used at well under one percent. It ferments, which is why the level is low rather than none. Amounts vary by brand and recipe, so always check the label of the exact product.
