Is Der Markenzwieback 3x12 Keto?

The Ingredient Breakdown

When analyzing a product for the ketogenic diet, we look for hidden sugars and high-carb fillers. Der Markenzwieback 3x12 relies on a traditional recipe, but the portion size is the key factor here. Let's look at the specific ingredients flagged in the analysis.

The primary ingredient is _Weizenmehl_ (wheat flour). Strictly speaking, wheat is a grain and is high in carbohydrates. However, in the context of a single Zwieback rusk, the amount of flour used is minimal enough to fit within a 20-50g daily carb limit. The product also contains various sugars: Zucker (sugar), Glukosesirup (glucose syrup), Traubenzucker (grape sugar), and Invertzucker (invert sugar). While these are 'non-keto' ingredients, the total weight of the slice is small, resulting in a carb count of less than 0.5g per piece.

We also see dairy derivatives like _Süßmolkenpulver_ (sweet whey powder) and _Kondensmagermilch_ (condensed skim milk). These add trace amounts of lactose (milk sugar), but again, the quantity is insignificant per serving. The presence of _Gerstenmalzextrakt_ (barley malt extract) usually signals higher carbs, but it is used here primarily for flavor and browning.

Nutritional Value

From a nutritional standpoint, Der Markenzwieback 3x12 is high in calories relative to its size, but very low in carbohydrates. A single rusk weighs only 5 grams. The carbohydrate content is approximately 2.6g per 100g, or roughly 0.13g per slice. However, most labels round this to 0.4g of carbs per slice.

Because the fat content is low (around 3.5% from sunflower oil) and the protein is moderate, this is not a 'high-fat' keto food. It fits the diet purely because it is low-carb. It fits well within the limits of a strict keto diet, where every gram of carbohydrate counts. It provides a crunchy, bread-like texture without the carb load of a slice of modern bread.
