Is Premium shells & cheese, original Keto?
If you are strictly following a ketogenic diet, you need to put the box of Premium shells & cheese, original back on the shelf. While it is a comforting and nostalgic meal, the ingredients list contains two major red flags for anyone in ketosis. Here is the detailed breakdown of why this classic pasta dish does not fit the low-carb lifestyle.
The Ingredient Breakdown
As a food scientist, looking at the ingredient label for Premium shells & cheese, original reveals a standard formulation for shelf-stable pasta. However, for the keto diet, standard formulation is a problem. The two primary ingredients that make this product incompatible with ketosis are the pasta itself and a specific additive in the sauce.
First, the pasta is made from Enriched macaroni product. The primary ingredient here is Wheat flour. Wheat flour is almost pure starch, which the body converts into glucose. On a keto diet, you typically limit net carbohydrates to 20-50 grams per day. A single serving of this pasta will likely consume the vast majority of that allowance, leaving no room for the other meals of the day. Even if you only eat half the box, the glycemic load is still too high to maintain a state of ketosis.
The second major offender is Maltodextrin found in the cheddar cheese sauce. Maltodextrin is a highly processed sugar substitute derived from starch (often corn, rice, or potato). While it has a high glycemic index (even higher than table sugar in some cases), food manufacturers use it as a thickener and preservative. For a keto dieter, maltodextrin is a hidden danger because it is often not counted as a sugar on the nutrition label in some regions, yet it impacts blood glucose levels almost instantly, triggering an insulin response that halts fat burning.
Nutritional Value
When analyzing the nutritional profile, the issue isn't necessarily the fat content—cheese sauce usually provides a decent amount of fat, which is good for keto. The issue is the carbohydrate-to-fiber ratio. Because the pasta is made of refined wheat flour, the net carb count is too high. You will likely see a significant amount of sugar listed in the nutrition facts (usually around 2-4 grams per serving) combined with a low fiber count.
For a product to be considered 'Keto-friendly,' it generally needs to have high fat, moderate protein, and very low net carbs (usually under 5-7g net carbs per serving). Premium shells & cheese, original fails this test because the majority of its calories come from carbohydrates derived from the wheat and the maltodextrin. It is a calorie-dense meal that is high in processed carbs, making it a poor choice for weight loss or metabolic health on a keto plan.
