Asparagus Nutritional Comparison
Asparagus calories: raw spears, cooking fat, and portions
The cited USDA entry lists raw asparagus at 20 calories per 100 grams. Spear count is not a fixed serving because thin and thick spears weigh differently; trim the woody ends and weigh the edible portion when a closer value matters.
How this food is commonly served in the U.S.
For a U.S. side dish, steamed or microwaved asparagus can use a preparation-specific entry. Roasted or grilled asparagus needs the cooking oil added, while hollandaise, Parmesan, bacon, and butter belong to the finished dish rather than the vegetable.
When to use another entry
Frozen plain asparagus and canned asparagus should be checked against their package labels. Water, brine, salt, sauce, and drained weight can make them different from the raw USDA reference.
