How can the blessing that descends upon the middle of the food be reconciled with the prohibition against eating from its middle and the command to eat from its sides?

The Prophetic traditions clarify that blessings in food descend from its top and middle. The Prophet, peace and blessings be upon him, guided to eat from the sides of the dish and to preserve the top and middle of the food. He forbade eating from its top and middle because it removes blessings from the food, and also because it is considered bad manners and gluttony.
