No bread like product will last a month without some pretty serious preservatives that isn't frozen. And it'll probably be taste awful well before them.
I'd be taking a long hard look at whatever this product is, and honestly a lot of the other stuff you may eat.
Mass produced food companies are not your friend. They want cheap stuff ebay keeps people happy. Health and well being wouldn't even make the list.
Freshly baked bread lasts quite a while, certainly longer than a week. White wheat longer than whole grain ones, but even those will last without any additional preservatives.
Of course it doesn't taste as good as freshly baked bread, but if it gets moldy only after a few days, it was already old or you didn't store it well enough.
I don't think anyone excepts the average American diet is anything but trash.
Back in 2013 at least, the effort I had to go to in Houston to find bread without sugar, milk without sugar, and butter that was actually butter was insane. Let alone getting to eating out!
A flour based food, full of preservatives will keep for a week. Bread does not :-)
