A bagel is a factory-made, yeast-leavened disk of refined flour, water, and a cocktail of additives. You're not getting a real food, just a processed product designed to be addictive and easy to consume. What's left of the wheat has been stripped of its nutrients and replaced with preservatives and artificial flavor enhancers.
Why trash
Dense refined wheat — one bagel has the same carbs as 4 slices of bread. And that's before the cream cheese.
Try instead
Almond flour flatbread or sourdough bread
