How Many Calories Are in Bloomer Bread? A Comprehensive Nutritional Guide

November 26, 2025 •

3 min read

According to typical nutritional data, a single slice of white bloomer bread can contain anywhere from 100 to over 150 calories, with one popular UK bakery product providing 149 kcal per average 62g slice. This variation highlights that the exact number of calories in bloomer bread depends heavily on its specific recipe and portion size.

Quick Summary

Bloomer bread calories vary by manufacturer and slice thickness, but a single slice of a typical white loaf ranges from 100 to 150 kcal. Nutritional differences are significant between white and wholemeal varieties, with added seeds also impacting the final calorie count.

Key Points

Calorie Variation: The number of calories in bloomer bread varies by brand, recipe, and portion size, so checking the nutritional label is recommended.
White vs. Wholemeal: White bloomer is lower in fibre, whereas wholemeal and seeded versions offer more fibre, nutrients, and can aid with satiety.
Carbohydrate Source: As a white bread, bloomer is primarily a source of carbohydrates for energy, with minimal fat.
Toppings Influence Calories: The total calorie count is significantly affected by the choice of spreads and fillings, such as butter, jam, or cheese.
Homemade vs. Commercial: Homemade bloomer bread offers greater control over ingredients, portion size, and potential calorie content.
Portion Control is Key: Be aware that hand-cut slices can be larger and more calorie-dense than standard pre-sliced versions.
Balanced Approach: Enjoying bloomer bread in moderation and with healthy toppings can be a part of a balanced diet.

Understanding Bloomer Bread Calories

Bloomer bread, a classic British loaf with a distinctive oblong shape and a crisp crust, is a staple in many kitchens. While the basic ingredients of flour, water, yeast, and salt are simple, the final calorie count can vary. The density of the loaf, the thickness of the slice, and the specific flour used are all key factors influencing its nutritional profile. Most commercially available white bloomers have a similar calorie density, though homemade versions can differ based on the baker's technique and ingredients used.

Calorie Breakdown by Manufacturer

For example, referencing nutritional information from UK sources reveals the following typical figures. Warburtons' Bakers Bloomer specifies 149 kcal per 62g slice. Another retailer, Tesco, lists its white bloomer at 103 kcal per slice (based on a 400g loaf). This difference is largely due to the weight and size of the individual slice, proving that 'a slice' is not a standardized measurement across brands. Therefore, it is crucial to check the packaging of your specific bloomer bread for the most accurate calorie information.

The Role of Ingredients in Bloomer Bread Nutrition

The choice of ingredients plays a major role in determining the health benefits and calorie content of bloomer bread. A standard white bloomer is made with refined white flour, while healthier variants incorporate different grains or seeds.

White Bloomer

A traditional white bloomer is primarily a source of carbohydrates, providing quick energy. Its minimal ingredients mean a lower fat and sugar content compared to some enriched or specialty breads. However, as the bran and germ are removed during the refining process, it offers less fibre and fewer micronutrients than wholemeal bread.

Wholemeal and Seeded Bloomers

For those seeking more nutrients, wholemeal or seeded bloomers are excellent alternatives. A wholemeal bloomer uses whole wheat flour, which contains more fibre, B vitamins, and minerals. The addition of seeds like sunflower, pumpkin, and linseed further boosts the nutritional value by adding healthy fats, fibre, and extra protein. Naturally, these additions also increase the overall calorie density.

Bloomer Bread vs. Other Bread Types

To put the calories of a bloomer into perspective, comparing it with other popular breads can be helpful. The following table provides a general comparison based on typical values per 100g.


Bread Type	Typical Energy (kcal) per 100g	Typical Fibre (g) per 100g	Key Characteristics
White Bloomer	230-250	2.0-2.4	Soft crumb, crusty exterior, lower fibre.
Wholemeal Bloomer	240-260	5.0+	Denser, higher fibre, more nutrients.
Baguette	~275	~2.5	Long, thin, crusty, similar to bloomer but often more calories per weight.

Making Healthier Choices with Bloomer Bread

If you are mindful of your calorie intake, there are several ways to enjoy bloomer bread as part of a balanced diet.

Choose the right variety: Opt for a wholemeal or seeded bloomer over a white one to increase your fibre and nutrient intake. The higher fibre content helps you feel fuller for longer, which can aid with weight management.
Control your portions: Be aware of your slice size. Hand-cut slices from a large bloomer can be significantly larger than pre-sliced bread and thus higher in calories. Moderation is key.
Watch your toppings: The condiments and spreads you add can quickly increase the overall calories. Consider healthier options like avocado, lean protein, or a light spread of hummus instead of thick butter or sugary jam.
Bake your own: Making your own bloomer allows for full control over the ingredients and portion sizes. You can experiment with different flours or add-ins to boost nutrition. For inspiration, you can find various recipes, including this classic white bloomer recipe from the Great British Bake Off.
Toast for a change: Toasting does not alter the calorie count but can be a satisfying way to enjoy your bread. It is important to remember that any added toppings will contribute extra calories.

Conclusion

In summary, the number of calories in bloomer bread is not a fixed figure, but a variable depending on the brand, recipe, and portion size. While a single slice of white bloomer typically contains 100-150 calories, switching to a wholemeal or seeded variety can provide significant health benefits through increased fibre and nutrients. By being mindful of your slice size and choosing healthier toppings, bloomer bread can certainly be a delicious and fulfilling part of a healthy diet, rather than a foe to your calorie goals. The key is to make informed choices based on your personal dietary needs and preferences.

Frequently Asked Questions

An average slice of white bloomer bread, such as the 62g serving from a brand like Warburtons, contains approximately 149 calories. Smaller or homemade slices will have fewer calories.

A standard white bloomer is nutritionally comparable to most other white breads. However, its free-form baking and ingredients can lead to a denser loaf. Wholemeal or seeded bloomers are a healthier choice due to higher fibre and nutrient content.

The calorie count per 100g is generally similar between white and wholemeal bloomers. The main nutritional difference is that wholemeal varieties offer more fibre, vitamins, and minerals, which can make them more satiating.

Yes, adding seeds to bloomer bread, as with a seeded bloomer, increases the calorie density. Seeds are packed with healthy fats and protein, which are higher in calories than the base flour.

Yes, bloomer bread can be part of a balanced diet when consumed in moderation. Portion control and healthier toppings are crucial, as is considering the wholemeal or seeded varieties for increased fibre.

To reduce calories, use a single slice or half a sandwich, opt for a wholemeal bloomer, and choose lighter, healthier fillings like lean protein, vegetables, or hummus over high-fat spreads and cheeses.

Yes, homemade bloomer bread can have a different calorie count. The calorie content depends on the specific recipe, the types of flour used, and whether you add fat like butter or oil.

For store-bought bread, always refer to the nutritional information label on the packaging, which provides specific data per 100g and per serving.
