Is Christ’s body subject to processes of digestion?

The Catholic Answers

The substance of Christ’s body is not subject to processes of digestion or to any chemical reactions. The qualities of bread of course behave in their normal way, undergoing a change as they are affected by digestion. Our Lord’s substantial presence ceases as these qualities cease to retain those characteristics proper to bread.
