Soda bread calories come to 223 for one 74 g slice, or 301 per 100 g of baked Irish soda bread. Look at the sugar line first. A slice carries 16.2 g of sugars, which is a lot for a bread. Slice thickness also moves the total quickly, because soda bread is usually cut in thick wedges.

A thick slice is a 223-calorie decision
The USDA slice weighs 74 g and lands at 223 calories. That is heavier than many sandwich-bread slices, and soda bread is rarely cut thin. A round loaf gets broken into chunky wedges, so a single piece can easily match or pass that weight.
A smaller 2 oz portion (57 g) comes to 172 calories, which suits a side for soup. Two slices reach 445 calories and 148 g of bread. Three slices hit 668 calories, which is a full meal's worth of energy before butter or jam goes on top.
The whole 537 g loaf holds 1,616 calories, about 81% of a 2,000-calorie daily value. Five slices from it already add up to 1,114 calories. If you bake at home, cutting the loaf into even pieces is the simplest way to know what you are eating.
Two thirds of the energy is carbohydrate
Carbs supply 66% of the calories in soda bread, fat brings 26%, and protein only 8%. Per 100 g that is 51.1 g of carbs, 9 g of fat and 6.5 g of protein. This is a starch-and-butter loaf, not a protein food.
Protein per slice is 4.8 g, about 10% of the daily value. Even two slices give just 9.6 g. If you want a breakfast that keeps you full, the protein has to come from what you put next to the bread.
Fat is higher than in a plain lean loaf. Of the 9 g per 100 g, 4.5 g is saturated, against a daily value of 20 g. Cholesterol is 54 mg per 100 g, which points to butter, eggs or buttermilk in the dough. A slice carries 6.6 g of fat before any spread.
Sugar and sodium both run high for a bread
The USDA entry lists 21.9 g of sugars per 100 g, so a 74 g slice holds 16.2 g. That is closer to a sweet quick bread than to a savory loaf. The recipe behind this row likely includes sugar and often raisins, and the brands on the page include versions with raisins and caraway seeds.
Sodium is the other row to watch. Baking soda and salt push it to 445 mg per 100 g, and one slice has 329 mg, or 14% of the daily value. Three slices bring 988 mg. The whole loaf has 2,390 mg, which is 104% of the daily value on its own.
Fiber does little to balance this. A slice gives 1.7 g, and 100 g gives 2.3 g against a 28 g daily value. If you watch sugar or sodium, treat soda bread as an occasional treat rather than your daily toast.
Pair one slice with protein, not a second slice
One slice fits easily into most days at 11% of a 2,000-calorie daily value. The trouble starts with toppings and refills. Butter and jam stack fat and sugar on a bread that already has plenty of both.
Soda bread works best as the side, not the meal. Serve a single slice with eggs, smoked fish, a bean stew or a bowl of vegetable soup, and let those foods carry the protein and fiber. That gives you the taste without the 445 calories of a second slice.
Store-bought loaves vary in size and recipe, so check the label on brands like Whole Foods Market or Walmart. For a homemade wedge, BodyPal can log the slice from a photo so the portion is counted at its real size.
How does soda bread compare?
Here is how soda bread stacks up against Hawaiian bread, Syrian bread and zucchini bread, per 100 g and per usual serving.
Verdict: For the fewest calories pick Syrian bread at 275 per 100 g with only 1.2 g of fat, or a 115-calorie slice of Hawaiian bread if you want something sweet. Soda bread at 301 per 100 g sits close to zucchini bread at 306, so treat it as a quick bread, not an everyday loaf.
