What changes the calories
- Sautéing or stir-frying green onions adds the calories of any oil or butter used, which can easily outweigh the onion itself.
- Using only the green tops or only the white bulb changes things slightly, since the figures here are for the whole onion, tops and bulb together.
- Portion habits matter more than the onion: a garnish of a tablespoon or two is very different from a cup used in a salad or pancake.
- Green onions in dips, sauces or dressings usually come with calorie-dense bases like sour cream, mayonnaise or oil.
Tips for logging it accurately
- For a garnish, log it by the tablespoon (1 tbsp chopped is about 2 calories); for larger amounts, weigh it in grams.
- Log any cooking oil, butter or sauce separately so the green onion entry stays accurate.
- In BerryFit, snap a photo of your meal and then check that the garnish and any oil are included before saving.
