What does this say about FODMAPs?
This USDA record does not establish a FODMAP rating or a tested serving limit for lettuce. Use this page to understand the preparation and nutrition, and discuss food-specific guidance with your dietitian.
The nutrition calculator uses grams for raw green leaf lettuce. It does not measure FODMAP content, determine a personal tolerance, or account for other ingredients.
Use the matching preparation
The nutrition record is green leaf lettuce. A salad may also contain croutons, onion and dressing; the leaf values cannot describe the whole bowl.
