Food is any substance consumed to provide nourishment, energy, and sustenance to living organisms, primarily humans and animals. It can be derived from plants, animals, fungi, or other sources and is typically rich in essential nutrients like carbohydrates, proteins, fats, vitamins, and minerals.

Food serves not only as a basic necessity for survival but also as a cultural and social cornerstone, with its preparation, consumption, and symbolism varying across different communities and traditions. It can be enjoyed in countless forms, from raw and minimally processed to highly complex dishes, and it is often associated with flavors, textures, and aromas that stimulate the senses.

Examples include fresh fruits and vegetables, grains, dairy products, meats, seafood, spices, and sweets, each contributing to a diverse range of culinary experiences. Food is also celebrated in festivals, rituals, and daily life, symbolizing unity, identity, and creativity.
