Answer 1

Answer:

Bread is one of the most popular foods around the world.

Typically made from wheat (or alternative grains), yeast, and other ingredients, bread stays fresh for only a short period before it starts to go bad.

It may even grow mold and become unsafe to eat, so it’s helpful to know how to keep it fresh for as long as possible.

This article explains how long bread typically lasts, how to tell whether it’s safe to eat, and how to increase its shelf life.
