A person's dietary habits are firmly rooted in their cultural, religious, and physiological surroundings. These habits not only have an impact on an individual's health but also on the standards that are prevalent in society as a whole. Jainism is an ancient religion that originated in India. It promotes a way of life that places an emphasis on non-violence (ahimsa) towards all living creatures. This approach extends to dietary choices, which has led to a diet that is mostly vegetarian and places stringent limitations on the intake of some foods, notably those that are thought to contain living forms. In the same way, the circadian rhythm, which is an innate biological clock, is responsible for regulating a variety of physiological processes, including as digestion and metabolism, in accordance with the day-night cycle. In this review study, the confluence between Jain dietary practices and the principles of circadian rhythm is investigated. The purpose of this research is to shed light on how adherence to Jain dietary rules may impact circadian health and vice versa. The purpose of this study is to provide insight on the complex interaction between cultural traditions and biological rhythms in the process of forming dietary habits and their consequences for health outcomes. This is accomplished by evaluating the timing of meals, practices of fasting, and the possible alignment with circadian cycles.
