As Islam guides towards good in both physical and spiritual life, balanced and healthy nutrition has been taken very well in the Qur’ān and the Sunnah. Food not only affects the human body; it has a significant impact on man’s spiritual life as well. The recommendation for healthy nutrition in Islam can be viewed from the perspective of Maqāsid al-Sharī’ah, which constitute the prime objectives of the Islamic Sharī’ah aimed to preserve one’s Dīn, life, progeny, property, honour, and intellect. Hence Islamic injunctions regarding food, its nature, and ways and means of its consumption assume primary importance for physical health and religious and spiritual well-being. In Islam, the aim of eating is the obedience of Allāh. This study aims to assess analytically the nature and importance of healthy food and nutrition in Islam. it is an approach for understanding diet and nutrition in Islam and its effects on promoting health within society. based mainly on the primary sources of the Qur'an, Ḥadīth, and other Islamic literature, the significance of the use of a diet compatible with the nature of the human body, manners of fostering hygienic principles, and ways and means of improving nutrition in the society are discussed.
