White Castle System Inc. has 241 distinct products indexed in the USDA FoodData Central Branded Foods database, each with a full nutrition label submitted through the USDA's data partnership program. Across the catalog, the average product carries 305 calories per standard serving, a figure that sits inside the broader packaged-food landscape but only gains meaning when you zoom into individual items. Branded food entries are refreshed as manufacturers update formulations and label data, so values here reflect the most recent submission to USDA rather than a frozen-in-time snapshot.

The brand's highest-protein offering is TURKEY & SMOKED CHEDDAR SLIDERS, TURKEY & SMOKED CHEDDAR at 21.9g per 100g, useful if you are scanning for protein-dense picks within this lineup. On the other end, DUSSELDORF MUSTARD is the lowest-calorie product at 100 calories per 100g, a useful anchor for portion-controlled eating. These edge-of-range products matter because averages hide the spread: two products from the same brand can differ by 400+ calories or 30g of sugar depending on variety, flavor, and portion.

Because USDA branded data is self-reported by manufacturers, nutrient values reflect what White Castle System Inc. prints on its packaging, the same numbers a shopper sees on-shelf. This makes side-by-side brand comparisons reliable for calorie, macro, and sodium decisions, and directly transferable to apps like MyFitnessPal or Cronometer that pull from the same FDC source. Use the comparison tool to stack up to three White Castle System Inc. products head-to-head, or filter the grid by our sort options to surface the highest-protein, lowest-sodium, or lowest-sugar choices across all 241 items.
