Within the Bahá’í tradition, fasting occupies a central spiritual place while dietary rules remain comparatively simple. Each year there is a designated nineteen-day period, from March 2 to March 20, during which believers abstain completely from food and drink between sunrise and sunset. This fast culminates in the celebration of Naw-Rúz, the Bahá’í New Year, and is understood not as an act of bodily mortification, but as a means of cultivating detachment from material things, deepening prayer, and strengthening inner discipline. The obligation to fast applies to healthy Bahá’ís from the age of 15 until 70, marking a significant span of adult life as a recurring rhythm of spiritual renewal.

The law of fasting is tempered by a wide range of compassionate exemptions, which reflect the faith’s concern for both physical well-being and practical realities. Those who are ill, elderly and weak, traveling, or engaged in heavy labor are exempt, as are pregnant and nursing women. Women during menstruation are also exempt, and are encouraged instead to turn to specific prayers and remembrance, so that the time remains spiritually oriented even without physical abstention. In this way, the fast becomes less a rigid legal requirement and more a disciplined yet merciful framework for spiritual growth.

Outside of the annual fast, the Bahá’í teachings on diet emphasize moderation and moral responsibility rather than extensive prohibitions. Alcohol is forbidden when used for pleasure, though it may be taken medicinally under the care of a competent physician, and the non-medical use of narcotics or other mind-altering drugs is likewise prohibited. Tobacco and other habits harmful to health are strongly discouraged, and overeating or gluttony is viewed as inconsistent with the spiritual dignity of the human being. Meat is permitted, and while the writings suggest that a predominantly plant-based diet may be more fitting for humanity’s future, no mandatory vegetarianism is imposed.

Within these broad principles, considerable cultural and personal flexibility is preserved. Believers are free to follow the healthy customs and cuisines of their own societies, provided these do not conflict with the core spiritual laws. Care of the body is regarded as part of one’s spiritual responsibility, yet the focus remains on inner transformation rather than on elaborate dietary codes. The result is a pattern of life in which a brief but intense annual fast, combined with ongoing moderation and avoidance of harmful substances, serves as a quiet but steady reminder of the soul’s primacy over the appetites of the body.
