Is Old Fashioned Blue Cream Soda Keto?

The Ingredient Breakdown

As a food scientist, looking at the label of Old Fashioned Blue Cream Soda reveals a classic soda formulation that is entirely incompatible with low-carb living. The primary issue lies in the sweetener used.

The second ingredient listed is cane sugar. This is a high-glycemic carbohydrate that causes a rapid spike in blood sugar and insulin levels. On a keto diet, the goal is to keep insulin low to maintain fat burning (ketosis). Consuming a drink sweetened with cane sugar will immediately halt ketosis. Even a small serving size likely exceeds the daily carb limit of a standard keto diet (which is often 20-50g of net carbs per day).

Additionally, the product contains FD&C Blue #1, a synthetic colorant. While not a carbohydrate, many health-conscious consumers on keto prefer to avoid artificial dyes due to potential inflammatory responses or sensitivities. The presence of sodium benzoate (a preservative) and citric acid are standard for shelf stability and flavor balance, but they do not offset the metabolic impact of the sugar.

Nutritional Value

While specific nutritional panels can vary slightly by bottler, a standard 12-ounce serving of a full-sugar cream soda typically contains between 150 to 160 calories, all of which come from carbohydrates. You can expect roughly 39 to 42 grams of total carbohydrates per serving.

Because the soda contains zero fat and negligible protein, the macronutrient ratio is 100% carbs. On the keto diet, fat is the primary fuel source. This soda provides zero nutritional value in terms of healthy fats or electrolytes. It is essentially 'empty calories' in liquid form. Drinking this would take up your entire daily carb allowance without providing satiety or essential nutrients.
