A food pyramid is a visual representation of a balanced diet, categorizing foods according to their nutritional value and serving recommendations. It typically emphasizes the importance of consuming a variety of food groups, such as grains, fruits, vegetables, proteins, and dairy, while highlighting the need to limit fats, sugars, and processed foods. By following the pyramid's guidelines, individuals can make healthier dietary choices, ensuring they receive essential nutrients to support their overall well-being and promote health.
