On Good Friday, it is traditional and required for Catholics age 14 and older to abstain from eating meat (flesh meat including beef, pork, chicken, and turkey) as a form of penance to honor the sacrifice of Jesus Christ. Good Friday is specifically one of the obligatory days of fasting and abstinence in the Catholic Church. Many Catholics choose to eat fish instead on this day. This practice is meant to commemorate Jesus' sacrifice, as he gave up his flesh on Good Friday. Abstaining from meat is considered an act of reverence and penance.
Therefore, eating meat on Good Friday would not align with traditional Catholic observance, which calls for abstinence from meat on this holy day.
In summary, Catholics generally do not eat meat on Good Friday and instead eat fish or other non-meat foods in recognition of the solemnity of the day.
