Indian cuisine is characterized by a wide variety of regional styles and sophisticated use of herbs and spices. The staple foods in the region are rice (especially in the south and the east) and wheat (predominantly in the north). Spices originally native to the Indian subcontinent that are now consumed world wide include black pepper; in contrast, hot chili peppers, popular across India, were introduced by the Portuguese.

India's culture is marked by a high degree of syncretism and cultural pluralism. It has managed to preserve established traditions while absorbing new customs, traditions, and ideas from invaders and immigrants and spreading its cultural influence to other parts of Asia. Traditional Indian society is defined by relatively strict social hierarchy. The Indian caste system describes the social stratification and social restrictions in the Indian subcontinent, in which social classes are defined by thousands of endogamous hereditary groups, often termed as jātis or castes.
Traditional Indian family values are highly respected, and multi-generational patriarchal joint families have been the norm, although nuclear family are becoming common in urban areas. An overwhelming majority of Indians have their marriages arranged by their parents and other respected family members, with the consent of the bride and groom. Marriage is thought to be for life, and the divorce rate is extremely low. Child marriage is still a common practice, with half of women in India marrying before the legal age of 18.
