Starfruit
What it is
Starfruit, also called carambola, is a fruit with a ridged shape. This profile describes the raw edible fruit.
What it does
For the named reference food, USDA lists 31 kcal, 6.73 g carbohydrate and 2.8 g fiber per 100 g edible portion. The table gives additional nutrients for that same food form. These figures describe composition, not an effect on a disease or a recommended serving.
Research context and ingredient forms
Reference food: Carambola, (starfruit), raw. These are historical SR Legacy data from the April 2018 release, published in FoodData Central in 2019. A different variety, preparation, water content, or commercial recipe can change the result. For a matching food, a portion estimate scales each value by edible portion grams divided by 100.
Using this information
Use the table as a composition reference, not as a reason to overlook the kidney-disease precaution. Juices and concentrated preparations are not assessed by this table.
Considerations
People with kidney disease should avoid starfruit. The National Kidney Foundation warns that substances in starfruit can affect the nervous system when the kidneys cannot clear them adequately.
