The Messenger of Allah (ﷺ), used to say after taking food or drink:

اَلْحَمْدُ لِلَّهِ الَّذِي أَطْعَمَ وَسَقَى وَسَوَّغَهُ وَجَعَلَ لَهُ مَخْرَجًا

Alhamdu lillahilladhi at'ama wasaqa wasawwagahu waza'ala lahu makhrazaa

Praise be to Allah Who has given food and drink and made it easy to swallow, and provided an exit for it.
