USDA Nutrient Database for Standard Reference
is an impartial database of food counts. Since US labels can declare that that a serving has 0 carbs per serving, even if it has .9, it's always better to believe a source that has no vested interest in selling you a product. I've always used it along with Corinne T. Netzer's Complete Book of Food Counts.

The USDA Database is more useful to use because it lists different measurents for food such as grams, tablespoons and ounces.

This is the USDA listing for 1 oz. of generic cream cheese:

Water g 15.238
Energy kcal 98.941
Energy kj 413.910
Protein g 2.140
Total lipid (fat) g 9.886
Carbohydrate, by difference g 0.754
Fiber, total dietary g 0.000
Ash g 0.332

From Corinne T. Netzer's Complete Book of Food Counts, 1 oz. of Philly cream cheese, regular, not fat free soft or whipped is written as: <1
