Sweeteners — FODMAP Guide
Sugars, syrups, and sweeteners rated for FODMAP safety
Low FODMAP (Safe)
No. Erythritol is the exception among sugar alcohols — Monash rates it as low-FODMAP at standard servings. About 90% is absorbed in the small intestine (versus ~50% for xylitol and sorbitol), so very little reaches the colon to ferment. Very large doses can still cause loose stools.
No. Pure maple syrup is considered low-FODMAP and is a safe sweetener for people with IBS when used in moderate amounts (up to about 2 tablespoons). It is one of the best-tolerated natural sweeteners on a low-FODMAP diet and is widely recommended as a replacement for honey.
No. Pure monk fruit extract is low-FODMAP at any typical sweetening amount and generally well-tolerated by people with IBS. The catch: many "monk fruit sweeteners" on shelves are blends — check the label for inulin or erythritol-xylitol mixes.
No. Stevia is low-FODMAP and safe for IBS because it contains no fermentable carbohydrates, sugars, or sugar alcohols. It is one of the best sweetener choices on the low-FODMAP diet. Check labels on stevia blends — some contain erythritol, inulin, or other additives that may affect digestion.
No. Regular white sugar (sucrose) is considered low-FODMAP and does not trigger IBS symptoms at normal serving sizes. Unlike honey or agave, sucrose contains balanced glucose and fructose, which aids absorption. Most people with IBS tolerate it well, though excessive sugar intake is not advisable for overall health.
High FODMAP (Avoid or Limit)
Yes. Agave syrup is very high in fructose — it contains up to 90% fructose, making it one of the highest-FODMAP sweeteners available. Even small amounts can trigger significant bloating, gas, and diarrhea in people with IBS. It should be completely avoided on a low-FODMAP diet. Use maple syrup or stevia instead.
Yes. High-fructose corn syrup (HFCS) is a major IBS trigger because it contains excess fructose that overwhelms the body's absorption capacity. It is found in thousands of processed foods including sodas, condiments, breads, and snacks. Reading labels to identify and avoid HFCS is one of the most impactful steps for managing IBS.
Yes. Honey is very high in excess fructose and is one of the strongest sweetener-based IBS triggers. Even a single teaspoon can cause bloating, gas, and abdominal discomfort in fructose-sensitive individuals. Maple syrup or white sugar are much safer sweetener alternatives on a low-FODMAP diet.
Yes. Sorbitol is a sugar alcohol and one of the primary FODMAPs that triggers IBS symptoms. It is poorly absorbed by everyone, but people with IBS are especially sensitive. Sorbitol is found in sugar-free gum, mints, diet foods, and naturally in stone fruits like apples, pears, and cherries. Avoid sugar-free products.
Yes. Xylitol is a polyol (sugar alcohol) and one of the highest-FODMAP sweeteners. Even small amounts — as little as 1g — can trigger bloating, urgent diarrhea, and cramping in people with IBS. It is hidden in sugar-free gum, mints, candy, and many "keto" or "low-sugar" products.
