How Many Calories Are in One Slice of Multiseed Bread?

December 3, 2025 •

4 min read

One slice of medium-sized multiseed bread typically contains between 90 and 130 calories, but this can vary significantly depending on the brand, slice thickness, and specific recipe. Its dense nutritional profile of fiber and protein makes it a popular choice for health-conscious consumers, yet understanding the calorie count is key for proper dietary planning.

Quick Summary

The calorie count of a single multiseed bread slice is influenced by its size, weight, ingredients, and seed content. A deeper look at the nutritional breakdown helps contextualize its energy value relative to other breads.

Key Points

Average Calorie Range: A single slice of multiseed bread typically contains 90 to 130 calories, but this can vary widely.
Weight and Thickness are Key: The weight of the slice, not just its size, is the most accurate indicator of its calorie content.
Check the Label: For precise calorie tracking, always refer to the specific nutrition facts on the product packaging.
Multiseed vs. Other Breads: Multiseed bread often has a higher calorie and nutrient density than white bread due to its seed and fiber content.
Don't Forget Toppings: Added toppings like butter or spreads significantly increase the total calorie count of your meal.
Nutritional Value Beyond Calories: Multiseed bread is rich in beneficial fiber, protein, healthy fats, and micronutrients.

Understanding the Calorie Count in Multiseed Bread

Unlike standard white bread, which has a relatively consistent calorie count, the energy value of multiseed bread can fluctuate considerably. A typical medium slice (around 33-50 grams) generally falls in the 90 to 130-calorie range. This variation is largely due to the specific formulation used by different bakeries and manufacturers. The quantity and type of seeds incorporated can add to the fat content and, subsequently, the overall calories. Seeds like flax, sesame, and sunflower are calorie-dense, healthy fats that contribute to the bread's total energy, along with its fiber and protein content.

Factors Influencing Calorie Content

Several factors play a role in determining the final calorie count of a slice of multiseed bread:

Slice Thickness and Weight: A thicker, heavier slice will naturally contain more calories than a thinner one. It is essential to check the label for the serving size in grams, as a 'slice' can be ambiguous across brands.
Flour Type: Whether the bread is made with whole wheat, refined white, or a mix of different flours will alter its nutritional profile. Whole grain flour adds more fiber, which can impact the net carbohydrate calculation, though not the total calories.
Seed Variety and Amount: The specific seeds used, such as flax, chia, pumpkin, and sunflower, all have different fat and protein content, directly affecting the calorie total. Some breads are more generous with their seed content than others.
Additives: Some commercial breads include added sweeteners, oils, or other ingredients that can increase the calorie count. Reading the ingredient list and nutritional information panel is always the best practice.

Comparing Multiseed Bread to Other Bread Types

To put multiseed bread's calories into context, it's helpful to compare it with other popular bread varieties. The nutritional differences highlight why multiseed is often considered a more nutrient-dense option, despite having a similar or slightly higher calorie count per slice compared to some lighter options.


Bread Type	Approx. Calories per Slice	Key Nutritional Benefits	Considerations
Multiseed Bread	90-130	High in fiber, protein, and healthy fats from seeds. Contains vitamins and minerals.	Calorie count varies by brand; can be higher than plain white bread due to seeds.
White Bread	60-80	Low in fiber and protein, quickly digested, provides simple carbohydrates for energy.	Low nutritional value; made from refined flour, lacks whole grain benefits.
Whole Wheat Bread	70-100	Good source of fiber, vitamins, and minerals; made from whole grains.	Generally lower fiber than multiseed, but a solid, healthier alternative to white.
Sourdough Bread	90-110	Easier to digest due to fermentation, lower glycemic index.	Nutrient content can vary; often contains less fiber than multiseed options.

How to Accurately Track Calories for Multiseed Bread

For those who need precise calorie counts for their diet, relying on a generic average is not ideal. Here is a step-by-step process for accurate tracking:

Check the Label: Always examine the nutrition facts on the specific bread loaf you purchase. The manufacturer’s label will provide the most accurate information regarding calories per serving.
Measure Serving Size: Use a kitchen scale to weigh a slice of your bread. This will help you determine its exact weight and calculate the calories based on the "per 100g" or "per serving" information provided on the package.
Log Your Toppings: Don't forget to account for any additions. A pat of butter, a drizzle of oil, or a spread of peanut butter can significantly increase the total calorie intake. One tablespoon of butter, for instance, adds about 100 calories.
Use Nutrition Apps: Calorie-tracking apps can simplify the process, often containing databases with information for specific food brands. However, cross-reference with the product label to ensure accuracy.

The Nutritional Benefits of Multiseed Bread Beyond Calories

While calories are a crucial metric, they don't tell the whole story. Multiseed bread offers several nutritional advantages that make it a valuable addition to a balanced diet. The added seeds provide a boost of fiber, which aids in digestion and promotes a feeling of fullness, potentially supporting weight management. Furthermore, seeds are an excellent source of healthy unsaturated fats, contributing to heart health. The protein content, while not as high as in meat or eggs, is a significant benefit for a plant-based item, helping to build and repair body tissues. Lastly, the diverse seeds in the bread offer a range of micronutrients, including minerals like manganese, magnesium, and iron.

Conclusion: Making Informed Choices

Determining the exact number of calories in a slice of multiseed bread requires careful consideration of the specific product. A general estimate of 90-130 calories per slice serves as a useful starting point, but checking the nutrition label on your chosen brand is essential for accuracy. Beyond the calorie count, multiseed bread is a highly nutritious option, offering valuable fiber, protein, and healthy fats that support overall health and wellness. By understanding these nuances, you can make informed choices that align with your dietary goals while still enjoying a delicious and wholesome food.

Frequently Asked Questions

Not necessarily. While they have similar total calories per 100g, a slice of multiseed bread might have slightly more or fewer calories than whole wheat, largely depending on the slice thickness and overall ingredient mix. Multiseed bread often has more fat from the added seeds, but also more fiber.

Multiseed bread is considered healthier because it's typically made with whole grains and contains added seeds. This significantly boosts its fiber, protein, and healthy fat content compared to nutrient-stripped white bread.

Yes, absolutely. The calorie count can vary significantly between brands. Differences in flour type (e.g., whole wheat vs. refined), slice thickness, and the quantity and type of seeds used all impact the final nutrition. Always check the label of your specific brand.

For a thin-sliced multiseed bread, the calorie count per slice is typically lower, often falling into the 50-90 calorie range. Brands like Dave's Killer Bread offer thin-sliced options with lower calorie counts.

Adding a single tablespoon of butter will add approximately 100 calories to your slice of multiseed bread. This can quickly double or more your total calorie intake for that serving.

Multiseed bread can be beneficial for weight loss. Its high fiber and protein content can increase satiety, helping you feel fuller for longer and reducing overall calorie intake. However, portion control is still important due to the calorie density from the seeds.

The most accurate method is to weigh your slice of bread on a kitchen scale and calculate the calories based on the 'per 100g' value on the nutritional label. You can then add the calories for any spreads or toppings you use.

The seeds, such as flax, chia, and sunflower, are a rich source of healthy unsaturated fats, fiber, protein, and various minerals like manganese, magnesium, and iron.
