What changes the calories
- Brands vary in how much sugar they add, so sweeter fish sauces can have slightly more calories than the figures shown.
- Fish sauce is usually mixed into dipping sauces and dressings with sugar, lime juice or oil, and those added ingredients often contribute far more calories than the fish sauce itself.
- Because it is so strongly flavored, typical portions are small, so the amount you actually pour matters more than the per-100 g figure.
- Cooking does not add calories to fish sauce, but any oil used in the same stir-fry or marinade does.
Tips for logging it accurately
- Measure fish sauce with a tablespoon or teaspoon rather than pouring straight from the bottle, since splashes are easy to underestimate.
- If you make a dipping sauce like nuoc cham, log the sugar, oil and other ingredients separately, or save the whole recipe in BerryFit and log your portion.
- Check your bottle's label for added sugar, and adjust your entry if your brand differs noticeably from a standard ready-to-serve fish sauce.
