Pope Shenouda III
Daniel and his companions also ate vegetables.
They ate vegetables (Dan 1:12) and were determined in their hearts not to defile themselves with the King's meat and wine. (Dan 1:8).
We see the Prophet Daniel say while fasting: “I ate no pleasant food, no meat or wine came into my mouth, nor did I anoint myself at all, till three whole weeks were fulfilled.” (Dan 10:3).
