About Bun
A bun is a type of small, often rounded bread originating from various cuisines worldwide and commonly associated with European bakery traditions. Buns are typically made from flour, water, yeast, and sugar, and can be enriched with eggs, milk, or butter for added flavor and texture. Nutritionally, a standard bun contains about 266 kcal, 8 grams of protein, 51 grams of carbohydrates, 4 grams of fat, 2.7 grams of fiber, and trace amounts of calcium and iron. While buns provide quick energy due to their carbohydrate content, they are typically low in vitamins and minerals unless fortified.

Common Questions About Bun Nutrition
Is a bun high in protein?
A standard bun contains approximately 8 grams of protein per serving (about 100 grams). While it provides a decent protein amount for a bread product, it is not considered a high-protein food compared to sources like meat, legumes, or eggs.
Can I eat a bun on a keto diet?
Buns are typically not keto-friendly as they contain around 50.7 grams of carbohydrates per serving, which makes up the majority of their nutritional value. Keto diets usually restrict daily carb intake to 20–50 grams, so eating a bun would likely exceed these limits.
Are buns healthy?
Buns can be part of a balanced diet, but they are relatively high in carbs (50.7 grams) and calories (266.7 per serving). They are also moderate in sodium (400 mg per serving) and contain 5.3 grams of sugar, which may be a concern for those managing blood sugar or sodium intake. Whole-grain buns with higher fiber content (2.7 grams or more) may offer more health benefits compared to refined white buns.
How many buns should I eat in one serving?
One bun (approximately 100 grams) is generally considered a single serving. Depending on your dietary goals, a half bun may be more appropriate if you are watching your calorie or carb intake. Pairing it with high-protein or fiber-rich toppings can help balance the meal.
How does a bun compare to a whole-grain or low-carb alternative?
A standard bun is higher in carbs and lower in fiber compared to whole-grain or low-carb buns. Whole-grain buns typically offer more fiber (around 4–5 grams) and micronutrients, while low-carb buns may have as few as 2–10 grams of carbs but often include added protein or alternative flours. Both alternatives are better choices for low-carb or nutrient-dense diets.
