Frequently asked questions

How much fiber is in iceberg lettuce?
2 cups shredded of iceberg lettuce, about 110 grams, contains 1.3 grams of dietary fiber. That is 1.2 grams of fiber per 100 grams and 5% of the 28 gram daily value.
Is iceberg lettuce high in fiber?
Not especially. Iceberg Lettuce has 1.3 g per serving, which ranks 46 of 60 vegetables in the FiberUp database. It still counts toward plant diversity, but the fiber in a meal will come from elsewhere.
Is the fiber in iceberg lettuce soluble or insoluble?
About 23% of the fiber in iceberg lettuce is soluble (0.3 g) and 77% is insoluble (1 g). Soluble fiber forms a gel that slows digestion and feeds gut bacteria; insoluble fiber adds bulk and speeds transit.
How many servings of iceberg lettuce would reach a daily fiber goal?
It would take about 20 servings to reach 25 g (the adequate intake for adult women) and 30 servings to reach 38 g (adult men). Spreading fiber across several foods is easier and better for gut bacteria diversity.

Values are per typical serving from USDA FoodData Central and standard references, rounded to one decimal. Actual fiber varies with variety, ripeness, and preparation. This is general nutrition information, not medical advice.
