Is Grapes (green / red) Low FODMAP?

Serving thresholds

Thresholds are per sitting. FODMAP load stacks across a meal — two “low” servings of different foods can still add up.

Which FODMAPs are in grapes (green / red)?

During reintroduction, test the group above one at a time — tolerating grapes (green / red) depends on your personal threshold for Fructose, not on the food itself.

Good to know

Grapes are fructose-dominant (≈8.1 g fructose vs ≈7.2 g glucose per 100 g, USDA), giving ≈0.93 g excess fructose per 100 g. The Varney 2017 cutoff of <0.4 g excess fructose per serving sets the low-FODMAP ceiling at roughly a small handful.

Where these numbers come from

• Peer-reviewed paper: Varney J et al. (2017) FODMAPs: food composition, defining cutoff values and international application. J Gastroenterol Hepatol 32(S1):53–61.
• USDA food composition: USDA FoodData Central — composition database (public domain).
• Derivation note: Excess fructose ≈0.93 g / 100 g (USDA fructose 8.13, glucose 7.20). At 40 g serving = 0.37 g excess fructose, below the 0.4 g Varney 2017 fresh-fruit cutoff.
• Derivation note: At 60 g, excess fructose ≈0.56 g per serving — above the low cutoff but below the high-FODMAP threshold.
• Derivation note: At 90 g, excess fructose ≈0.84 g per serving — exceeds the 0.7 g threshold typically used for the high-FODMAP boundary.

Phase derives serving thresholds from published research and food-composition data so every number is auditable.
