Neither the FDA nor the USDA have defined the term Low-Carb or Low-Carbohydrate for use in food labeling. The Alcohol and Tobacco Tax and Trade Bureau (a US Government agency) has issued an interim standard defining Low-Carb as no more than 7 grams per serving for alcoholic beverages. The Center For Science In The Public Interest suggests that a Low-Carb food should have no more than 6 grams per serving.

For our purposes, we will use the 7 gram figure used by the Alcohol and Tobacco Tax and Trade Bureau. This is based on Total Carbohydrates in the soup mix, not as prepared. Any additions to low-carb soup mixes can change the carbohydrate content of the finished soup. The Total Carbohydrates is found in the Nutrition Facts for each product.
