What it does
For the named reference food, USDA lists 102 kcal, 11.4 g protein and 3.42 g total fat 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: Mollusks, oyster, eastern, wild, cooked, moist heat. 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
The cooked oyster record is distinct from raw oysters and other species. Shell weight is not part of the edible portion used in the nutrient table.
