Leek
What it is
Leeks are vegetables eaten for their edible bulb and leaf portions. The selected USDA profile specifies the raw bulb and lower leaf portion.
What it does
The raw reference provides 1.8 g of fiber, 64 micrograms of folate and 180 mg of potassium per 100 g. Folate supports normal DNA production.
Research context and ingredient forms
Trimming determines which plant portions remain in the food. A whole purchased leek weight, including discarded parts, should not be substituted for the edible portion described here.
Using this information
Weigh the prepared edible portion when using this table. A leek soup requires its own recipe calculation including stock, milk or cream, potato and any added fat.
