Breakfast is the first meal of a day, most often eaten in the early morning before undertaking the day's work. Among English speakers, "breakfast" can be used to refer to this meal or to refer to a meal composed of traditional breakfast foods (such as eggs, porridge and sausage) served at any time of day. The word literally refers to breaking the fasting period of the prior night. It has its origin in the Christian custom of fasting from food between the supper meal of one day and receiving Holy Communion the following morning (such a Eucharistic fast is still observed by Orthodox Christians, but is shortened to one hour before Mass for Roman Catholics). Foregoing the natural craving to eat was seen as an act of self-denial that honors God, while strengthening the religious resolve and faith of the believer.
