Fasting and Nutritional Health: The Impact of Religious Rituals on Nutrient Intake

Abstract

Religious fasting, an integral part of many spiritual traditions, significantly influences dietary patterns and nutritional health. This study investigates the impact of religious fasting rituals— such as those in Islam (Ramadan), Christianity (Lent), and traditional African spiritual practices—on nutrient intake, biochemical health markers, and long-term health outcomes. Using a mixed-methods approach combining dietary assessments, focus group interviews, and biochemical tests across religious groups in Abia State, Nigeria, this study reveals that while fasting may promote short-term detoxification and discipline, it can also lead to deficiencies in micronutrients such as iron, calcium, and vitamin B12 if not properly managed. Recommendations are provided for culturally sensitive nutrition education to help individuals maintain spiritual devotion without compromising health.
