A sub bun is a long, cylindrical bread roll typically used to make submarines or hoagies, popular in American and Italian-inspired cuisines. It is made primarily from wheat flour, water, yeast, salt, and sometimes sugar or oil for added texture and flavor. Sub buns can be enriched with nutrients such as folic acid, iron, and B vitamins, especially when made from enriched wheat flour. The nutritional profile of a standard white sub bun is approximately 200-250 calories per bun, with around 40-50 grams of carbohydrates, 1-2 grams of fat, and small amounts of protein. Whole-grain varieties offer additional fiber and micronutrients such as magnesium and selenium compared to refined versions.
Store sub buns in a cool, dry place or freeze for extended freshness. Always seal in an airtight bag to prevent drying out.
A typical sub bun contains around 6-8 grams of protein, depending on the size and recipe. Made primarily from white or whole wheat flour, its protein content comes from the grains used, but it is not considered a high-protein food.
Sub buns are generally not suitable for a keto diet as they are high in carbohydrates. A regular sub bun contains roughly 40-50 grams of carbs, which would quickly exceed the daily limit of most keto plans focused on keeping carbs below 20-50 grams per day.
Sub buns may pose concerns for those watching their carb or calorie intake; a single bun typically contains 200-300 calories and can be high in refined carbohydrates. White sub buns may also lack fiber and micronutrients compared to whole-grain varieties, and individuals with gluten sensitivity should avoid them unless made with gluten-free flour.
For a balanced meal, one sub bun is recommended as a serving when paired with nutrient-rich fillings like lean protein, vegetables, and healthy fats. Portion control is key, especially for calorie-conscious or low-carb diets.
Sub buns are larger and more calorie-dense than slices of sandwich bread, typically containing 200-300 calories compared to around 70-80 calories per slice of white or whole wheat bread. Sub buns also tend to be softer and chewier, making them ideal for sandwiches with substantial fillings, while other bread types may differ in flavor or texture based on ingredients.
