When sardines come in sauce, are they still good nutritionally?
Certainly. Other than the oil pack, sardines mainly come in tomato or mustard sauce. In these two sauces, the drained fish has about 20 fewer calories of fat and about four more calories of carbohydrate. Both sauces give the sardines slightly more vitamin A, and just a little less riboflavin. There is somewhat less niacin in the mustard pack, and only about half the day’s vitamin D instead of all of it.
