This literature review evaluates the authenticity and local authenticity of the Indian daily diet as it assesses the nature of Indian cuisine based on regional variations, culture, and cooking techniques. Defined as one of the most extensive and diverse cuisines in the world, India's food culture has been connected to geography, politics, history, religion, and socioeconomic conditions. This literature review brings together recent research on regional cuisine changes across India, comparisons and distinctions to cuisine around the world, and traditional cuisine retention to a conclusion that India's food culture is a reflection of life within the nation of India, where unity exists in diversity, but local variations reign true since people can embrace their regional identities while simultaneously sheltered under the Indian identity. Recent studies conclude that Indian food is more than food to eat since it serves a purpose for sociocultural identity, community integration, and traditional storage of information passed down from generation to generation.
