What does this say about FODMAPs?
This USDA record does not establish a FODMAP rating or a tested serving limit for potatoes. Use this page to understand the preparation and nutrition, and discuss food-specific guidance with your dietitian.
The nutrition calculator uses grams for raw potato, flesh and skin. It does not measure FODMAP content, determine a personal tolerance, or account for other ingredients.
Use the matching preparation
The values include both flesh and skin. Weigh the raw potato: a cooked potato loses or absorbs water, and chips include added fat.
