Fennel
What it is
This entry covers fennel bulb as a vegetable. USDA's raw-bulb record is the nutrition reference. Fennel seed, oil, tea, and extracts are different forms and are not assigned the bulb's values.
What it does
The bulb reference supplies 3.1 g of fiber, 414 mg of potassium, and 12 mg of vitamin C per 100 g. It also contains 7.3 g of carbohydrate. These amounts describe a weighed food portion rather than a supplement dose.
Research context and ingredient forms
A study of fennel seed or an extract would not by itself establish the same effect for eating the bulb. This food entry makes no digestive-treatment claim from another preparation.
Using this information
Match the plant part when looking up nutrition. Use the edible bulb weight for this table and account for other recipe ingredients separately. A teaspoon of seeds should not be calculated from a bulb profile.
