Which of the following best defines a balanced diet?

A balanced diet is characterized by its inclusion of all food groups in appropriate proportions, ensuring that the body receives the necessary nutrients it needs to function optimally. This definition embraces a variety of food sources, including fruits, vegetables, grains, proteins, and dairy, allowing for a diverse intake of vitamins, minerals, and macronutrients. Each food group contributes unique nutrients essential for maintaining health, supporting bodily functions, and preventing nutritional deficiencies. This holistic approach contrasts with other definitions that limit certain food types or focus solely on specific nutrients, which can lead to imbalances and potential health risks. By prioritizing diversity and proportion in food choices, a balanced diet promotes overall well-being and helps in maintaining a healthy weight, energy levels, and bodily functions.
