Only include the edible portion represented by this record. Bones and other discarded parts should not be included in the weight you enter.

Values are scaled from the USDA figures per 100 g. Calories are rounded to a whole number; gram values to one decimal. A dash means the source does not provide that value. Portions are reference measurements, not serving recommendations.
Weigh the portion that matches the record.
Raw and cooked chicken do not have the same nutrition per gram: cooking changes moisture and weight. Use a weight taken at the preparation stage named below. A raw package weight should not be entered directly against a cooked-chicken record, and a skinless entry does not account for skin.
For a bowl or salad, weighing the chicken separately makes it easier to record the amount served. Add cooking oil, breading, gravy, dressing, or marinade ingredients as separate foods when they are part of the meal. A whole breast is not a standard portion across packages, so grams are useful when the piece you have does not match a listed household measure.
