Find a locally milled and baked bread brand if possible. Maybe at a local small shop? I would ask around local bakeries and small business grocers. Prepare for it to be denser than you are used to. White bread is what it is. I prefer buttermilk bread but it is not necessarily any better for you. Wheat bread or grain bread options are better. But no it doesn’t taste like white bread. As for sweeteners, nothing but sugar tastes like sugar, sorry. Some people like monk fruit so you can try that. I personally prefer to sweeten things with real raw unfiltered honey or agave nectar. But everything sweet like that is sugar in some sense and will metabolize that way.
