Staple Food: The food that is eaten most frequently by a population in a specific region. Example: Rice in West Bengal and South India, Corn (Maize) in Punjab.
Food Habits: People are categorized as Vegetarians (who eat plant products and milk) and Non-vegetarians (who also eat meat, fish, and eggs).
Age-specific Food: Infants usually consume milk ( + nutrients), while elderly people prefer soft, easily digestible food.
