Which of the following is a characteristic of a balanced diet?

A balanced diet is characterized by a variety of foods from all food groups, which ensures that the body receives a wide range of nutrients necessary for optimal health. This includes a combination of carbohydrates, proteins, fats, vitamins, and minerals. By incorporating various food groups, individuals can meet their nutritional needs more effectively and support overall well-being.

The other options do not reflect the principles of a balanced diet. A high intake of carbohydrates only lacks the necessary diversity of nutrients found in other food groups and can lead to nutritional imbalances. Exclusively vegetarian options may not provide all essential nutrients unless carefully planned, and minimal protein consumption can hinder muscle maintenance and immune function. Thus, the essence of a balanced diet lies in its variety, promoting a holistic approach to nutrition.
