White bread typically refers to breads made from wheat flour from which the bran.
Also the germ layers have been removed (and set aside) from the whole wheatberry as part of the flour grinding or milling process.
This produces a light-colored flour.
This milling process can give white flour a longer shelf life by removing the natural oils from the whole grain.
Removing the oil allows products made with the flour, like white bread, to be stored for longer periods of time avoiding potential rancidity.
So can hamsters eat white bread?
Yes they can nibble at it.
However, it is not the best food for hamsters to eat as it has no nutritional value for them.
So don’t give them too much and make sure there isn’t anything else like butter on it.
