Is lettuce (butter/boston) low FODMAP?

This serving ladder belongs to butter lettuce rather than every salad leaf. Cos or romaine lettuce has different larger-portion references, so a generic lettuce answer can hide useful differences. The weights concern the raw leaves before dressing and other salad ingredients are added.

Lettuce (Butter/Boston) and IBS: what to know

If using an IBS food diary, identify the lettuce variety when possible and note the amount in your portion. A mixed bag or restaurant salad may not tell you how much butter lettuce is present. Keeping dressing and toppings in the record helps separate the leaf portion from the whole dish. Supporting background: Monash: Low FODMAP shopping list. General shopping context; not evidence for this exact variety or its full portion table.

Gut-friendly ways to eat lettuce (butter/boston)

Wash the leaves and drain off surface water before weighing what you plan to eat. Use them in a salad or as a soft wrap around a separately checked filling. Weigh whole and torn leaves the same way rather than relying on how tightly they fill a cup. For another leaf option, compare iceberg lettuce using its own guide.
