Good to know
Tartar sauce is mayonnaise plus sweet relish — inherits the relish HFCS and onion load.
Where these numbers come from
- Derivation note: Mayonnaise + sweet relish (HFCS, onion) + capers; fructose and fructan loads above cutoffs at standard serves.
- Peer-reviewed paper: Varney J et al. (2017) FODMAPs: food composition, defining cutoff values and international application. J Gastroenterol Hepatol 32(S1):53–61.
Phase derives serving thresholds from published research and food-composition data so every number is auditable.
