Bread connoisseur and founder of Modernist Cuisine Nathan Myhrvold shares that supermarket bread is a better choice than its artisan counterpart if you won't be using it quickly.

This is thanks to the added preservatives and ingredients designed to extend its lifespan, which homemade and artisanal bakery bread doesn't have.

If you use proper storage tactics, like keeping your loaves out of the fridge, a supermarket loaf can potentially last a week or more, thanks to its preservatives.
