How do you know?
The manna fed to the Jews in the wilderness from heaven? It was the food of angels.
Evidently... angels have saliva and digestive abilities similar to our own.
Yet he gave a command to the skies above
and opened the doors of the heavens;
he rained down manna for the people to eat,
he gave them the grain of heaven.
Human beings ate the bread of angels;
he sent them all the food they could eat.'
Psalm 78:23-25
Just because angels have the power to make themselves invisible? That does not mean they have no real body.
Genesis 18. Have you studied it? The angels that later went to Sodom to deliver Lot's family, ate human food!
He said, “If I have found favor in your eyes, my lord, do not pass your

to your servant.”
“Very well,” they answered, “do as you say.”
So Abraham hurried into the tent to Sarah. “Quick,” he said, “get three seahs of
the finest flour and knead it and bake some bread.”
Then he ran to the herd and selected a choice, tender calf and gave it to a servant,
who hurried to prepare it. He then brought some curds and milk and the calf that
had been prepared, and set these before them.
While they ate, he stood near them under a tree." Genesis 18:3-8
