Soda bread
Just as long as you use fresh ingredients, and if the bread is baked fresh too, this bread will be healthy. Organic, non-brominated flour is much more beneficial than stale bleached white flour. If you make this bread, we would encourage you to use freshly milled flour as much as possible.
And even though sugar is added to it, the amount used for this loaf is not too overpowering. Organic raw sugar is always a better option rather than bleached white granulated sugar.
The same goes for the bread, milk, and other ingredients. If you use high-quality and fresh ingredients or buy from someone who has, then yes, this bread has the great potential to be hearty and healthy.
